Chamrider Battery is an ebike battery manufacturer and electric bicycle battery factory with 12 years of experience. 

Electric bicycles are fantastic, but they are also an investment, and a crucial component of that investment is the battery. Unfortunately, just like your old phone now needing to be charged every five minutes, electric bicycle batteries inevitably degrade over time and lose some of their capacity. If you want to learn how to keep your electric bicycle battery healthier for longer, check out our expert tips and advice.

1. Pedal effectively and use gears

The fewer times you charge and discharge the battery, the longer its lifespan. It makes sense to try to find a balance of power during each ride, meaning pedal wisely.

Electric bicycle motors are designed to work with a normal to high pedaling cadence; they're most efficient and consume the least amount of energy. Bosch recommends keeping your cadence above 50, avoiding slow grinding, and making full use of the lovely gear distribution that comes with your bicycle.

Similarly, make full use of the modes provided with your electric bicycle—ideally, you want to use the lowest power setting you can handle to seek greater range, but not if it slows down your cadence to a crawl.

2. Avoid full charging and discharging of the battery

Batteries themselves have built-in computer chips to regulate their output and charging. This means they will never completely deplete and ruin themselves in the process.

However, performing full charges and discharges on the battery every time you go out does impose a higher load on the battery. So, if you consistently go out with a fully charged battery and then bring it back inside, you'll need to rinse and repeat. Instead, try to stop riding before the battery is completely drained on each ride... easier said than done.

3.Charge the electric bicycle battery at room temperature

Now, this is a big one. Charging the battery at room temperature is crucial, with the ideal temperature being between 10-20°C (50-68°F), definitely not below freezing. ChamRider advises charging the battery indoors, in a dry place with a smoke detector (lithium-ion batteries have proven to be very safe, but in extremely rare cases, they can catch fire if short-circuited). Charging outside of this temperature window will result in reduced range and shorter battery lifespan, as colder objects have increased resistance, causing a decrease in electrical capacity.

Riding for a few hours in cold weather is not bad for your battery since it will reach a certain temperature regardless of the environmental conditions. However, starting from warm is important. This means that if you're driving a van, place it in front of you and the heater, and put it on the bike immediately before riding. Also, avoid taking it directly from a cold shed; warm it up inside beforehand.

During the summer, don't leave it in direct sunlight either, just like your phone, as high temperatures increase the load on the battery. In theory, if the battery overheats, the motor will automatically shut off, just like on a laptop, but we haven't experienced such a situation.

Avoid fully depleting or fully charging the battery

If you haven't ridden your electric bicycle for a few days, weeks, or months, it's important not to leave it fully charged or completely drained. Bosch recommends keeping it at around 30-60% capacity, while Shimano suggests keeping it at 70%. Recharge the battery every 6 months, and of course, fully charge it before riding again.

Avoid excessive water usage around the motor and battery area

Clean carefully, avoid high-pressure cleaning

Bosch suggests removing the battery before cleaning the bike, while Shimano recommends keeping it in place to protect the terminals. Shimano's advice may be more practical in real-world application as there can be a significant exposure of wires splashed with mud and water if the battery is not installed.

We believe the best approach is to gently clean it vertically with a hose and sponge, then let it dry completely before opening it up.

Tips and Tricks

ChamRider suggests that if there is dirt or grime on the battery terminals (not the battery itself), you can clean them with a soft, dry brush or cotton swab.

Finally, reach out to the dealer who specializes in your motor and check the status of your battery. They will be able to inform you about the battery's condition and whether you're in a long-term storage situation or if there is any equipment damage.

Four

Electric bicycle questions you're afraid to ask:

1. Why does the charger get hot?

Converting the UK's 240V voltage to 36V for ChamRider results in some energy loss in the form of heat, typically around 10%, according to ChamRider. Charging automatically shuts off when the capacity is reached, so there is no overcharging or increased load.

2. Can battery manufacturers open the casing and replace a faulty battery like Tesla does?

No, it is not possible because the batteries need to be perfectly matched to avoid overcharging or over-discharging. It is technically feasible but a complex process, which would cost more money – acceptable for a £100,000 car but not for a £5,000 electric bicycle. As a point of interest, the Bosch PowerTube 625Wh battery has 50 individual cells inside.

3. How many cycles can the battery endure?

It depends on how you treat it. ChamRider states it can be charged up to 1,000 times, equivalent to normal usage for 7-10 years before the battery capacity starts to decline. Obviously, you would replace the bike before that, so theoretically, it can extend the lifespan of the bike. ChamRider guarantees that after 1,000 charging cycles, the battery will retain at least 60% of its original capacity.

ChanRider's warranty guarantees that within the warranty period (24 months after purchase, or 36 months from the date of battery purchase), the 400Wh, 500Wh, and 625Wh batteries will have at least 60% of their original energy capacity, and the 300Wh battery will have at least 70% of its original energy capacity. This is based on proper maintenance or 500 full charging cycles, whichever comes first. The brand states that with proper care, the lifespan can be much longer, as supported by lab tests and customer feedback.

4. Where do the batteries go when they are depleted?

Battery dealers, whether for bicycle batteries, phone batteries, or car batteries, have a responsibility to recycle the batteries. Different battery recycling programs exist throughout Europe, and in the UK, Valpak operates the largest compliance scheme. Interestingly, the UK tends to export its battery waste rather than recycling it domestically, primarily to France, Germany, and Poland.

Do you want to enjoy the fun of riding an electric bicycle? You can leisurely ride around your neighborhood or take on challenging bike paths during your daily commute. To achieve this goal, your e-bike components must be in perfect working condition. To enjoy the full experience of your electric bicycle, proper maintenance of a key component, the e-bike battery, is crucial.

As an e-bike owner, charging the battery is one of your primary tasks. This is because the battery determines the enjoyment of your riding experience and the range you can travel on a single charge. If you want to keep your e-bike battery in good condition, continue reading this article.

So, how do you charge an electric bike? To charge an e-bike battery, detach the battery pack from the e-bike and ensure it is turned off. Then, connect the original charger of your electric bike to a power outlet. Plug the charger into the battery, and finally, switch it on.

While it may seem simple, charging an e-bike battery correctly requires considering a few factors. Additionally, there are methods to enhance the battery's lifespan and efficiency with just a little sustained effort.

Charging an E-Bike Battery

The charging process for most e-bike batteries can vary based on the battery itself and the manufacturer. Nevertheless, you can still follow some general guidelines that will help you make the most of your battery.

Every e-bike comes with a battery pack, which can be likened to a battery chamber. Additionally, your e-bike is equipped with a port where you can insert the charger, allowing for easy connection to the battery. The port attachment may vary depending on the manufacturer's choice. However, these ports are typically located at the back of the e-bike seat or in the middle of the e-bike.

Typically, e-bikes are supplied with chargers that have two cable-powered ports. One end connects to the cable that connects to the power source, while the other end connects to the battery. If you're a gamer, it might remind you of your Xbox One power port.

Furthermore, each e-bike charger comes with indicator lights - usually a red LED when charging and a green LED when charging is complete. So, once your e-bike battery is low, remove the battery and turn off the switch. Then, insert the battery cable, connect it to the power source, and finally, switch on the power outlet.

Considerations When Charging an E-Bike

There are few factors that can affect battery performance and e-bike range. Riding mode, terrain, tire pressure, temperature, and user weight are important factors that influence the performance of the bike. Additionally, time is also a factor to consider when discussing battery health. Over time, all batteries degrade, regardless of usage.

The question remains, how can you extend the battery's lifespan? This can be achieved by charging the e-bike battery in the correct manner and following recommended charging practices. Here are some important tips to show you how to charge an e-bike battery:

Charge New Battery Pack for 12 Hours

After purchasing a new battery pack for your e-bike, it is essential to charge it for a minimum of 12 hours. The initial long charge helps the battery establish a good state after being taken out of the packaging. Additionally, it provides sufficient current for all batteries.

It is essential to regularly charge your battery.

Most e-bikes use lithium-ion batteries. Regular use and charging can prolong the lifespan of lithium-ion batteries. In general, it is not advisable to let your device fully deplete before charging. This rule applies to e-bikes as well. In most cases, it is best not to let the e-bike battery fully drain before the next charge.

Instead, it is recommended to try and charge the battery when it is at around 30% to 60% remaining capacity. Some battery experts suggest occasionally allowing a full discharge, approximately every 25 to 35 charges. Otherwise, always follow the 30% to 60% rule. Additionally, you should ride the bike regularly. This is because most batteries require regular use. Besides the obvious physical benefits, regular bike usage also ensures that you are regularly charging the e-bike battery.

Avoid Extreme Temperatures

Always avoid extreme temperatures. We cannot stress this enough. Cool or moderate temperatures are most suitable for your e-bike battery. The feeling of each e-bike battery is the same as your feeling in high temperatures.

Therefore, to prolong the lifespan of your e-bike battery, avoid riding in hot sunlight, especially during charging. During each charge, the battery should be placed in an environment that is not too cold or too hot. It is best to maintain a temperature of around 60°F to 70°F during charging.

Pay Attention During Charging

When charging the e-bike battery, avoid being far away from the charging point. Do not leave the e-bike battery connected to the charger for an extended period—consider 13 hours or more. Always avoid overcharging the battery. Overcharging the battery will decrease its efficiency faster.

Overcharging the bike battery can cause the battery to self-discharge to around 95% of its capacity. Then, the charger will attempt to charge it to 100% and continue charging. The slight discharge and continuous charging during this period can weaken the charging cycle and lead to battery aging. You can use reminders or timers on your mobile device to remind you to unplug the battery from the power outlet.
             

Do Not Store the Battery Empty

Sometimes, you may need to store an e-bike battery when going on a long trip. Perhaps your destination is farther than the range of your e-bike, or maybe you don't want to ride the bike for such a long distance. There's nothing wrong with that. However, avoid storing the battery at 0% state. Always try to store the battery at around 40% to 60% of its total capacity.

Note the Time Required to Reach Full Charge

The charging duration for each e-bike battery depends solely on the battery size or capacity. However, most e-bike batteries take approximately two (2) to six (6) hours to reach a full charge. Additionally, always keep in mind the charging rate of the e-bike battery.

For a charging speed of 15 miles per hour and a range of 30 miles, a battery will take up to 2 hours to charge fully. However, a battery with a range of 100 miles will require 4 hours to charge fully at a charging speed of 25 miles per hour.

Where to Charge the Battery

Since most e-bikes can be charged through a power outlet, you can charge the battery anywhere with an available power outlet. As long as there is enough space to accommodate the bike during charging, you're good to go. Additionally, ensure that your charging area is free from water and fire hazards.

Safety is Important!

Charging While Pedaling

Some e-bikes have a feature that allows you to charge the battery while riding. This is done when you apply the brakes, and it can extend the battery life by about 10%. However, this may make your e-bike more challenging to ride and also increase the cost of the e-bike.

If you're unsure about the duration your e-bike will last during a long trip, consider purchasing an additional battery for a better experience. This will help alleviate concerns about running out of battery power while riding.

Finally, before charging your e-bike battery, there are some additional measures you should always follow. Firstly, you should always avoid charging leaking or damaged batteries. Additionally, make sure to use the charger specified for the battery. Most batteries have a built-in management system that prevents overcharging, overvoltage, and overcurrent. This system works perfectly only when you use the designated charger to charge the e-bike battery.

Can I charge the battery to 100%?

For most e-bikes, lithium-ion batteries are the standard configuration. Lithium-ion batteries are good, and there's no harm in unplugging the battery early. Charging the bike battery to 100% also doesn't cause any harm. Let's quickly understand how e-bike charging works. When your e-bike battery is charging, it goes through two (2) cycles of charging. The first cycle is a rapid charge that replenishes about 90% of the charge capacity. So, unplugging the battery at this point means you've given the battery the best part of a "charge."

However, not all e-bikes have built-in indicators. On one hand, newer e-bikes use display screen systems to indicate battery level. On the other hand, older e-bikes may not have battery level indicators. If you're using an older model, there's no harm in charging the bike battery to 100%. Just be sure not to overcharge!

Can e-bike batteries be replaced?

E-bike batteries can be replaced at any time. The structure of e-bikes allows you to remove the battery for charging convenience. It's also an ideal choice for e-bike owners to have a spare battery for long trips. Additionally, if the battery becomes damaged or loses efficiency, you can replace the e-bike battery. Check out our article on choosing the best battery for your e-bike.

How to increase battery range for longer rides?

In general, there are several ways to increase the battery range of an e-bike for longer rides. The best method is to use a lower assist mode. If you pedal at a higher frequency than the battery's operating frequency, it will last longer.

Another option is to use the right gear at the right time. Higher gears make it easier for the e-bike to travel at higher speeds, while lower gears make it easier for slower speeds. So, you should try to change gears to adapt to your current road conditions. Additionally, shifting gears earlier rather than later can improve your riding experience with less power consumption.

For example, imagine approaching a stop sign and refusing to shift gears until you reach it. Accelerating back up to top speed can quickly drain your battery and may be challenging.

Furthermore, always pay attention to the power requirements of the e-bike. As speed increases, the power demand also increases significantly. This means that your battery will deplete faster when riding at high speeds. On the other hand, riding at lower speeds will help extend the battery range of your e-bike. Choosing lower gears and lower assist modes is a good way to prevent draining the battery quickly during high-speed rides.

What is the lifespan of an e-bike battery?

In general, most e-bike batteries can sustain up to 500 full charge cycles before they start to lose their effectiveness. This number is not a strict limit. Some batteries can last up to 1,200 full charge cycles. However, for pedal-assist e-bikes, depending on your riding style and battery capacity, you can expect to ride approximately 30,000 miles before the battery starts to deplete.

Additionally, most e-bike manufacturers offer a 2-year warranty for each user. The cost of replacing an e-bike battery can range from $500 to $800, depending on the shape and capacity of the battery pack.

What is the cost of charging an e-bike battery?

The cost of charging an e-bike battery depends on the electricity rate in your area and the battery capacity. Assuming you are in an area with an electricity rate of $0.12 per kilowatt-hour and you have a 10 amp-hour battery for your e-bike, the cost of charging the battery would be approximately $0.002 per mile, which is very inexpensive.

How to maintain an e-bike battery?

To maintain and keep the battery in good condition, it is best to store it in a cool place. A temperature range of approximately 32-104°F (0-40°C) is ideal for proper storage. Most e-bike owners prefer to store the battery in a garage as it can get too hot there. Instead, it is better to store it in a cool place with average temperature.

Additionally, it's important to handle the battery with care and avoid it coming into contact with water or other liquids. While e-bikes are waterproof, it's still important to take precautions before riding in the rain. Equally important is always using the charger provided by the manufacturer and not any other charger. Using chargers other than those specifically designed for the battery can potentially damage the battery or shorten its lifespan.

Charging the e-bike battery is the only way to use it, so make sure to instill safety and recommended practices into your charging habits. This is the only way to ensure the durability of your e-bike battery. Stay safe!

The electric bike battery is one of the most important parts of an electric bike and without it the electric bike will turn into a regular bike.With this importance, everyone is trying to get the best performance from the battery in order to increase his enjoyment of the electric bike.

One of the most frequently asked questions: Why is my ebike battery draining so fast? In fact, this question is an important but somewhat confusing question.The reason for this is that the word FAST cannot be measured, meaning the battery drained fast, i.e. some 15 minutes of riding your ebike.

Or drained fast, meaning if you used to  use  the ebike for 20 miles per one charge, and now you go 15 miles per one charge? That is why in this post we will answer the question Why is my ebike battery draining so fast?  from both sides.We will explain the reasons that lead to abnormal battery consumption and also the reasons that reduce the range of a single charge.

So that you have all the information you need to determine the causes of the battery problem and how to repair it.

Why is my ebike battery draining so fast? (the extreme condition reasons)

As a general rule, the battery drains fast as a result of damage to the internal cells of the battery or a problem with the BMS.

1-Damage Cell or Group of Cells.

The first and main reason why the electric bike battery drains fast is that there is damage to a cell or group of cells inside the battery, and the reason for this is that when there is a damaged battery cell the voltage becomes lower than normal, so the BMS “battery management system” completely shuts down the battery to save the internal cells of the battery.

To understand this point better, let’s take a quick look at how the BMS works.

How the BMS works:

Inside the battery of your electric bike are cells grouped together and each group is connected in series and connected to the BMS.

Through this connection, the BMS measures the voltage coming out of each group.

BMS is programmed to a minimum voltage & when the battery cells reach it, the BMS turns off the full battery completely.

Based on this, if you have only one cell or a group of cells damaged, you will find that the battery drains very fast.

In order to solve this problem, the damaged cell must be identified by measuring the voltage for each group of cells using a voltmeter

2-BMS Problem.

The second reason that may lead to the battery draining quickly is that there is a problem with the BMS unit itself.

The reason for this is that the BMS, as we mentioned, is the controller of the battery, so if there is a problem with the BMS and it is unable to read the battery cell voltage correctly, It will cause the battery to shut down quickly and you will notice that the battery is drained abnormally.

To solve this problem, you can reset the BMS or replace the BMS. You can see this post to learn the correct ways to do REST for BMS

Why is my ebike battery draining so fast? (The reasons for the low mileage)

In this part of the post, we will explain the most important reasons that reduce the miles you travel with your electric bike on a single charge.

1-Using Super Fast Charger.

One of the reasons that reduce the performance of the battery in general and reduce the long term is the use of a very fast charger because this will strain the battery cells and reduce their lifespan.

Based on my personal experience, I have noticed that the number of miles I travel when charging my bike battery with the original charger is more than the miles I travel when I use the fast charger.

Of course, you will need to use a fast charger in some situations, such as you need to charge on the go in case you are away from home,but do not make the fast charger your first option.

You can check out this post to learn how to choose a fast charger that is suitable for your bike battery.

2-Wrong storage habit.

When storing your electric bike battery, you should follow the rules that help maintain the life span of the internal cells and or these rules are to keep the charge rate around 75%.

We wrote this post that explains the best steps that you can take to maintain your bike battery during storage.

3-Using throttle only.

When you rely only on the throttle while riding your ebike, this will lead to the battery draining fast because you are making the bike do all the work.

This will lead to the fact that the motor will need to consume a lot of watts, which will reduce the range of a single charge.

4-Going uphills too much

When you use an electric bike up a steep hill, it takes a lot of the bike motor to give you the right torque to go up the hill.

This will also increase the battery drain and reduce the range of a single charge.

5- Riding in hot weather.

When you ride your electric bike in very hot weather, this will affect the movement of ions inside cells, which makes the chemical processes that occur inside the cell difficult.

This will greatly reduce the duration of a single charge and generally, most high-quality BMS will shut down the battery if the internal temperature of the battery reaches a certain degree.

6-Loading a Lot of staff.

Another reason for the battery depleting quickly is loading many things on the bike or towing a trailer.

This will lead to an increase in pressure on the motor to produce the highest torque, which will increase the battery consumption and thus reduce the battery range.

Conclusion

The reason for fast battery draining  (30 minutes or less) are often due to damage to some battery cells or a malfunction in the battery management system BMS 

On the other hand, there are several reasons that lead to the battery draining faster than normal, including the frequent use of a fast charger that is not commensurate with the capacity of the battery, improper storage of the battery, loading heavy things on the bike, and riding the bike in very hot weather.

Also, the continuous use of throttle only while riding and riding uphills a lot.

Battery Management System (BMS) is a technology specifically designed to monitor battery packs, which are organized electrically in an x-by-y matrix configuration to achieve desired voltage and current ranges for expected load scenarios.

The supervision provided by BMS typically includes:

1. Monitoring the batteries

2. Providing battery protection

3. Estimating the operational state of the batteries

4. Continuously optimizing battery performance

5. Reporting operational status to external devices

The overall goal of BMS is to optimize battery performance through intelligent management and protection, thereby extending battery life.

Types of Battery Management Systems

There are different types of battery management systems, each with its unique features and applications.

Some common types of battery management systems include:

1. Centralized BMS Architecture

2. Modular BMS Topology

3. Master/Slave BMS

4. Distributed BMS Architecture

Centralized BMS Architecture

A centralized BMS is a system where all battery management functions are handled by a single computer. Such systems are typically used in large-scale commercial applications where reliability and accuracy are primary considerations.

Modular BMS Topology

Modular BMS topology is a BMS that utilizes modules connected to the batteries. These modules can be placed at any location on the battery pack, allowing for easy addition or removal of functionalities as needed. Modular design also facilitates easy upgrades or replacement of components without impacting the overall operation of the system.

This topology is particularly suitable for applications that require a high level of flexibility and scalability.

Primary/Subordinate BMS

Primary/Subordinate BMS is a configuration where one master unit controls and communicates with multiple slave units. The master unit coordinates the overall operation of the system, while the slave units handle specific tasks or monitor individual battery modules. This configuration allows for distributed control and monitoring while maintaining centralized coordination.

Distributed BMS Architecture

Distributed BMS architecture is a system where each battery module has its own local BMS, and these local BMS units communicate with each other to collectively manage the battery pack. This architecture allows for a decentralized approach to battery management, providing redundancy and fault tolerance.

This topology is particularly well-suited for applications that require high levels of flexibility and scalability.


                       

The importance of Battery Management Systems

One of the most critical features of any electronic device is its battery. Without a reliable and robust battery, your device is essentially of little value—it might not even turn on!

While electronic devices continue to become more powerful and efficient, batteries have not necessarily become smaller or stronger. In fact, a study found that smartphone batteries have actually been getting larger in recent years!

Hence, the popularity of Battery Management Systems (BMS) among electronic manufacturers should come as no surprise. BMS plays a crucial role in ensuring that the batteries in electronic devices have the longest possible lifespan and reliable performance.

This is because it can help to reduce the number of battery packs that need to be manufactured (and/or purchased), as well as the associated expense. Additionally, a BMS can also provide additional warranty protection for devices.

The Battery Management System (BMS) serves several different functions. The Electrical Protection Management of the BMS helps protect the battery pack from overcharging, incorrect charging, and over-discharging. Capacity management assists in optimizing the battery pack's discharge voltage and capacity by monitoring charging/discharging cycles and adjusting battery parameters accordingly. The Thermal Management System (TMS) prevents thermal runaway of the battery by monitoring battery voltage, current, temperature, and fan speed.

Electrical Protection Management - Current:

BMS helps protect the battery pack from overcharging, incorrect charging, and over-discharging. Essentially, these management system functionalities help optimize battery performance by monitoring charging/discharging cycles.

Electrical Protection Management - Voltage:

One of the key functions of the BMS is voltage management. By monitoring the battery pack voltage levels and adjusting battery parameters (e.g., battery voltage) accordingly, the BMS helps prevent over-discharging or undercharging of the battery. This helps maintain optimal pack health and performance.

Thermal Management:

Thermal management is another important function of the BMS. By monitoring battery voltage, current, temperature, and fan speed, the BMS helps prevent thermal runaway of the battery. The thermal management system functionality also helps optimize battery pack performance by ensuring that the battery stays within safe operating limits.

Capacity Management:

BMS also assists in managing the capacity of the battery pack by monitoring charging/discharging cycles and adjusting battery parameters accordingly. This helps optimize battery performance while keeping the battery pack within a safe operating range.

Components of Battery Management System:

The Battery Management System (BMS) is a specialized hardware and/or software device that helps optimize the performance and lifespan of battery packs in electronic devices.

A typical BMS monitors the health (and condition) of individual batteries as well as the entire battery pack. It also provides accurate information on State of Charge (SOC), state of health, energy usage, and temperature of the battery. This makes it an essential tool for device manufacturers who want to ensure that their devices operate reliably even under harsh conditions.

In addition to improving device operation, the BMS also simplifies maintenance procedures. This is because it helps identify and diagnose issues early, minimizing the time and effort required to rectify problems.

               

Battery Management System (BMS) Operations and Maintenance

The Battery Management System (BMS) is a computer system that monitors, manages, and maintains battery charging, discharging, and status. The BMS can also predict when a battery may need replacement or repair.

BMS should be installed in any facility that uses or stores batteries, such as factories, power plants, hospitals, and schools. Having a BMS is crucial because batteries are critical components of many devices, from electric vehicles to mobile phones, and improper management can pose safety risks. 

The primary goal of the BMS is to maintain battery health and safety by monitoring the battery's charge level, temperature, and other performance indicators. It also provides warnings to users when the battery starts to lose capacity or approaches its maximum limits. Additionally, if the battery requires maintenance or replacement, it can initiate preventive maintenance procedures. 

Overall, a good battery management system helps ensure the safe and efficient use of batteries now and in the future.

Conclusion

As you can see, there are many benefits to using a Battery Management System in battery packs. The technology ensures not only fast charging and safe driving but also ensures that the battery is always fully charged.

Tips for removing an electric bicycle battery:

While removing the battery from an electric bicycle may seem straightforward and not overly complicated, there are some recommended practices to keep in mind.

When and why should you remove the battery from an electric bicycle?

For safety reasons and to maintain the health of the battery, it is recommended to remove the battery from the electric bicycle.

Additionally, when the external temperature exceeds 20 degrees Celsius or falls below 0 degrees Celsius, it is advised to take out the battery and store it in a dry, room-temperature environment to minimize stress on the battery.

Furthermore, by taking out the battery and keeping it indoors at home or in your workplace, it reduces the risk of theft.

Does using an electric bicycle without a battery affect its functionality?

Whether by choice or due to a depleted battery, an electric bicycle functions the same as a regular bicycle when the motor is not in use.

Regardless of the reason for riding without a battery, you can rest assured that it will not damage the motor or the bicycle. The only difference is that your muscles will bear the sole burden of propulsion.

The weight of an electric bicycle depends on the pedal-assist components and the inherent resistance of all the power system components. These factors will affect your riding experience without the battery.

Why are Rad Power Bike batteries challenging to remove?

Rad Power Bike batteries are difficult to remove because the battery terminals take up some space at the bottom, making it challenging to slide or pull the battery out by the terminals.

Therefore, you have to be careful to only push or pull the battery itself, not the terminals. Otherwise, your efforts will be in vain. Due to the battery and terminals being made of the same material and almost seamless, it's easy to forget this distinction.

Instead, look for any fractures. You must regularly lubricate the battery attachments to prevent them from becoming nearly hard to remove. You should lubricate the bike’s battery as well as the area where it attaches to the bike

Should I keep the battery on or off when it's on the bike?

When not using the bike, it is always advisable to remove the battery from the electric bicycle. There are a couple of reasons for this. Firstly, it is for safety considerations.

The cost of the battery is approximately one-third of the bike's cost, and electric bikes are more likely to be targeted by thieves. If an expensive bike is stolen, separating the expensive battery can mitigate the loss.

Is removing the battery enough for theft prevention?

It is not foolproof since people can still ride the bike without the battery, so it doesn't completely deter theft. Most bike thefts are crimes of opportunity. If someone with questionable morals sees an unlocked bike while out and about, they might think it's easier to ride away with it. So they hop on the bike, ride to their destination, and ultimately, it disappears.

Why is my e-bike battery not working as it used to?

For instance, your e-bike now only charges up to 48V when it used to reach 54V. Additionally, it has become weak and sluggish, with a sharp drop in battery level when accelerating.

1. End of battery life:

Your battery may have reached the end of its life. However, it could also have internal damage due to various factors such as age, number of charge/discharge cycles, and more.

2. Improper battery handling:

Mishandling the battery, such as using an incorrect charger type or voltage, causing short circuits on the terminals, can also result in similar damage within a relatively short period.

3. Possibly defective battery:

If you notice the battery quickly draining even when not in use, it may indicate a defect in the battery you have. Remove the battery pack from the e-bike and charge it on a bench for testing.

After charging, without disturbing the bike, check the battery. If your lithium-ion battery cannot hold a charge, it indicates a failure.

Conclusion

Knowing how to remove the e-bike battery can assist you in various ways. I believe it is essential to consider both the aesthetics of the bike with the battery neatly tucked away and its practicality, as well as the importance of simply removing the battery and taking it with you to a secure location.
