In the second half of 2022, we organized a picnic in Impression of the Mountain Fruit Park, it was time for all the staff to show their cooking skills. We divided the labor and cooperated, boys and girls played hands together, talked and laughed, cooked happily, we experienced the beauty in the mountain together.
When we arrived, we found the area was a very beautiful place. There are many trees, flowers and clear streams. We decided to set up our camp near the stream and started preparing food in the morning. Our colleagues are very involved and they bring all kinds of ingredients and tools, including chicken, potatoes, Onions, green peppers, flour, oil and spices.
We were divided into several groups. Each group was responsible for different tasks, such as chopping vegetables, cooking, frying eggs or baking fish. During the cooking process, we constantly communicate and interact, sharing our experiences and ideas. We feel very excited and energetic because we are working hard for ourselves and our dinner. When our food is ready, we begin to enjoy our own masterpiece, because the food is made by our own hands in nature. In the afternoon we started our outdoor games. We played Live Action cs, which is a fun outdoor activity that combines military simulation and shooting games for people to have fun and relax in the outdoors.
I had the honor to participate in a real person CS activity with my colleagues. The experience made me deeply feel the importance of teamwork and tacit cooperation, and also made me experience the stimulation and pleasure of shooting games. In the real people CS activity, we were divided into two groups, one is the red team, the other is the blue team.
Each of us was dressed in camouflage and armed with a dummy gun. After that, we began to fight. At the beginning, we didn't know how to cooperate, how to plan tactically, so our red team was always at a disadvantage. However, under the guidance of the coach, we gradually realized the importance of teamwork, we began to cooperate with each other, support each other and fight for the team. Some of us covered our teammates, others attacked the enemy, and by working together effectively, we gradually won. After half a day, harvest is full.
The world of electric bicycles is rapidly gaining momentum, captivating cycling enthusiasts worldwide. These innovative vehicles offer a plethora of advantages over conventional pedal bikes, revolutionizing the way we ride. However, amidst this growing trend, many riders find themselves grappling with questions about their e-bike's battery and its optimal charging routine.
One recurring query revolves around the frequency of charging an e-bike battery. Is it best to wait until the battery is completely drained or should you avoid it altogether? The answer lies in the electric bike's built-in battery indicator, which simplifies the charging process for riders. By heeding the indicator's suggestion, you can ensure optimal battery performance and longevity.
An e-bike battery is typically discharged when it reaches its maximum range, indicating the farthest distance it can cover on a single charge. This range varies depending on the e-bike model, with some offering only pedal-assist mode while others boast a throttle mode for effortless propulsion. Additionally, the level of assistance provided by the motor significantly affects the achievable range, even without utilizing the throttle mode.
Most electric bicycles offer a range of 22 to 50 miles, though certain models can surpass these limits. These estimates are based on relaxed pedaling. However, with consistent pedaling and a high-quality e-bike, you can extend the range to approximately 80 miles, unlocking a world of possibilities.
While the battery's capacity plays a crucial role in charging frequency, other factors also impact the range:
Battery Capacity: The battery's capacity determines the frequency of charging, with higher capacity batteries requiring less frequent charges.
Terrain Type: Uphill journeys necessitate increased motor assistance, drawing more current from the battery and reducing the range. Similarly, riding against strong headwinds mimics uphill terrains, albeit on a smaller scale.
Rider's Weight: Heavier riders demand more power from the motor, resulting in increased electric current consumption from the battery.
On the other hand, descending hills or utilizing minimal assistance on flat terrain can conserve battery power. But should you deplete the battery entirely during every ride?
To maximize battery life, it is advisable to avoid frequent full discharges. Instead, aim to charge the battery when it reaches around 30% capacity and alternate between charging at 30% and 60% remaining capacity. This alternating charging pattern helps preserve the longevity of lithium-ion batteries commonly found in e-bikes. However, a complete discharge once every 30 or 40 charges can be beneficial but is not necessary. Embracing the 30%-60% rule ensures regular charging, thereby extending the battery's lifespan and your riding pleasure.
When initially charging a new e-bike battery, a 12-hour charge is recommended to ensure all cells receive an ample supply of electric current. Subsequently, avoid fully charging the battery to prevent accelerated degradation. Instead, maintain a charge level between 40% and 70% for extended storage periods. Additionally, when charging, disconnect the charger once the battery reaches 90%-95% capacity to prevent overcharging.
To further enhance battery longevity, consider the following vital charging tips:
Storage Conditions: Avoid storing the battery in excessively hot or cold environments. Optimal storage temperatures range from 59 °F (15 °C) to 77 °F (25 °C) in a dry location.
Temperature Considerations: Refrain from charging the battery in temperatures below 32 °F (0 °C). Before charging during winter, ensure the battery reaches room temperature.
Safety Precautions: Place the battery and charger on a dry surface, away from flammable materials, humidity, and heat sources. Avoid covering the battery or charger during the charging process.
Manufacturer's Charger: Always utilize the charger provided by the manufacturer to prevent potential damage to the battery.
Monthly Charges: Even during extended periods of non-use, charge the battery at least once a month to maintain its health and performance.
In summary, a simple rule of thumb is to charge your battery after each ride, adhering to the 30%-60% alternating pattern. This ensures your e-bike is always ready to hit the road whenever you desire.
However, with high-capacity batteries like the Delfast 3.0, boasting an impressive range of 200 miles (321 km), less frequent charging may be necessary for short commutes or leisurely rides. The Delfast 3.0's control display provides accurate battery charge information, making it effortless to follow the 30%-60% rule and optimize your battery usage.
Embrace these charging tips and unlock the full potential of your e-bike battery. Ride with confidence, knowing you have extended the lifespan of your battery and embarked on countless electrifying adventure
When it comes to our passion for electric bicycles, we strive to maximize the benefits and enhance performance. Therefore, a common question arises: Can we add a larger battery to our e-bike to increase range and speed?
Yes, you can install a larger battery on your electric bicycle to achieve greater range and, in some cases, improve speed. However, this is not a DIY project. If you desire this feature, you may need to purchase a bike with expandable battery storage.
Read on to learn more about how battery life affects performance, the impact of removing the battery from the frame, and tips for improving e-bike range!
How does battery life impact e-bike performance?
Removing the electric bike battery from the frame.
Battery life refers to the total number of charge cycles (from 0 to 100%) a battery can endure before it stops working. Your battery's lifecycle will affect overall performance. Batteries nearing the end of their lifecycle will not last as long or hold charge effectively.
The expected lifespan of an e-bike battery depends on the battery type. The most common battery types include:
Lithium batteries, the most prevalent type, can typically handle around 1,000 charge cycles.
Nickel batteries have an estimated lifespan of around 500 charge cycles.
Lead batteries have a lifespan of approximately 300 charge cycles.
While battery lifespan is important and impacts performance, battery capacity and range are crucial factors in choosing a battery. Range refers to how far you can travel on a single charge, while capacity refers to the duration of the ride.
Not all brands and manufacturers accurately describe their model ranges, but as a general rule of thumb, here are some figures:
250-500Wh: Within this range, your bike will be very basic and standard, with an estimated range of 25 miles per charge.
500-800Wh: This range indicates entry into the high-end segment, typically providing a range of over 30 miles per charge.
800+Wh: These are premium and luxury battery series. With this type of battery, you can expect a range of over 40 miles per charge.
Think of capacity like a fuel tank on a car; the more it can hold, the longer you can travel. Battery capacity operates similarly; the larger the capacity, the greater the distance it can cover.
If you are considering upgrading to a larger battery for your current e-bike, be sure to check the capacity and range.
Can you retrofit an electric bicycle with a larger battery?
Not all electric bicycle batteries are interchangeable.
Electric bicycles come in various designs and configurations. If you have the knowledge and skills, you may be able to equip your bike with a different battery. However, for most people and many models of bicycles, the battery is integrated into the bike itself.
Let's take the example of the ChamRider Integrated Battery SSE-125 SEA LION II model. It comes with a removable integrated battery, and you can upgrade that battery, but you can only use parts provided by the manufacturer.To enhance the battery capacity and fully leverage the bike's performance, you would need to spend around $500, which is nearly half the price of the bike itself.
Can batteries with different voltages (36v, 48v, 52v, etc.) be interchangeable?
The answer to this question is somewhat complex as it largely depends on your specific model and manufacturer. Depending on the type of controller you have, it may be possible to accept a range of voltages such as 24v-36v or 36v-48v. You would need to look up the specific details of your model to determine this.
The concern here is that a higher voltage battery could potentially fry the motor and electronic components. Running a higher voltage battery on a model that doesn't support it can result in the motor being permanently damaged.
That being said, many manufacturers build in a significant safety margin to account for these types of situations. Nonetheless, it's important to check with your model and manufacturer to avoid damaging your electric bicycle.
Adding additional batteries (expanding) to an existing battery
Adding more batteries to an existing battery is not a straightforward task and is not suitable for beginners. If you're looking for an upgrade, it's generally better to choose a higher-end model in the long run.
When adding more batteries to an existing setup, you need to know what you're doing. Lithium-ion batteries, in particular, can be dangerous and may cause minor explosions. Assuming you don't encounter an explosion, adding additional batteries can lead to issues of imbalance, premature battery death, and potential battery failures.
Most importantly, if you don't know what you're doing, do not attempt this operation. Adding more batteries can damage the batteries and potentially be life-threatening.
Will adding a larger battery increase speed and range?
When it comes to increasing speed and range, adding a larger battery is not a simple task and is much more complicated than it may seem.
In short, adding a larger battery can be dangerous, damage your bike, or be a very complex issue that isn't worth the trouble. To increase the speed of your bike, you would need to somehow increase the battery capacity.
Capacity doesn't necessarily mean faster speed, but it can represent a larger range. Watt-hours (Wh) are the measurement unit used to determine the battery pack's capacity, which allows you to measure the range. To calculate it, multiply the voltage by the amp-hour rating of the battery pack. For example, a 36V 10Ah battery pack has a capacity of 360 watt-hours (36 x 10 = 360). Assuming you use about 20 watt-hours per mile, then you can travel 18 miles.
In theory, having a larger capacity battery would allow you to ride for a longer duration. However, this is not a simple task and should be left to professionals. But what is the best way to increase the range of an electric bike without adding a larger battery?
What is the best way to increase the range of an electric bike?
For an electric bike, how you use the bike is just as crucial to the battery and motor as the bike itself. The terrain you ride on, how you handle the bike, and even the wind can affect the bike's range.
How much does it cost to replace an electric bike battery?
The cost of an electric bike battery can vary widely, but typically ranges from $200 to over $900. The range depends on factors such as the brand, capacity, and quality of the battery.
Let's take the example of a battery like the ChamRider 36V 48V Electric Bike Battery . This battery has a voltage of 48V and a capacity of 10Ah, and it is priced quite reasonably. You won't get the support of a high-end brand, but this battery can provide a range of 20-30 miles on a single charge.
With options closer to or above $800, you'll be spending more on the brand and quality. Mid-range prices of $400-$600 should be sufficient to get the job done quite well.
Another factor that can affect the price of a battery is whether it is an external battery or an integrated battery. For integrated in-frame batteries, you may need to pay more compared to external options.
Please keep in mind that while the upfront cost may be high, purchasing a replacement battery is a worthwhile investment. Buying a replacement battery can effectively double your range and provide peace of mind in case of emergencies. The decision depends on you and your budget, but we highly recommend having a spare battery!

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 components as it transforms an ordinary bicycle into an electric one. On the other hand, it is also considered one of the most expensive parts of an electric bike, with prices ranging from $500 to $1000 for certain models.
Now, the question arises: Can electric bike batteries be repaired? Considering the cost of the battery and its significance to electric bike riders, it is a logical question to ask.
Can electric bike batteries be repaired?
Generally speaking, electric bike batteries can be repaired since their main components, such as the battery cells, BMS board, and wiring, can be easily replaced. Based on this, the battery can be repaired by changing these components.
Now let's discuss the most significant issues that can occur with electric bike batteries, their symptoms, and the possible solutions.
1.BMS Board Issues
The Battery Management System (BMS) is responsible for protecting the battery by regulating the flow of current into and out of the battery.
To understand how it works in practice, the BMS board is connected to all the cells in the battery and measures their individual capacities. When one cell discharges, the BMS completely shuts down the battery to prevent any potential damage.
From the functioning of the BMS, it becomes evident that charging or discharging is controlled by the BMS.
Therefore, if you find that the battery has some remaining charge but is unable to charge or discharge, it indicates a problem with the BMS.
How to solve the BMS Problems
To resolve BMS issues, there are generally two methods: resetting and replacing (I personally prefer replacement since BMS prices are not expensive either).
To reset the BMS, you can follow these steps:
1. Remove the outer cover of the battery.
2. Disconnect the cables connected to the BMS of the battery.
3. Connect the battery to the charger and start charging.
4. During charging, reconnect the BMS cables.
By performing the above steps, the BMS will be reset to its default settings.
Replacing the BMS Board.
BMS Main Cables
There are three main cables connected to the BMS:
(P-) cable is responsible for negative discharge to the connector.
(C-) cable is responsible for negative charging to the connector.
(B-) cable is responsible for the battery's negative terminal connection.
Tools Required:
Screwdriver
Soldering iron
Steps for replacing the BMS board:
1. Remove the outer cover of the battery.
2. Desolder the three main cables of the BMS.
3. Disconnect the connector connected to the battery.
4. Install the new BMS in the same position.
5. Resolder the main cables.
6. Connect the connector back to the battery.
7. Test the battery's charging.
If everything goes smoothly, reassemble the battery cover.
Important Note: In most cases, BMS damage is caused by faulty battery cells inside the battery. Therefore, it is advisable to measure the voltage of all the cells before reassembling the battery cover to ensure that all the cells are functioning properly.
2. Damage to One or More Cells
The second most common cause of electric bike battery failure is damage to one or more cells inside the battery.
In this case, you will be unable to operate the battery at all.
You can identify the damaged cells by individually measuring the voltage of each cell. You will find that most cells have a consistent reading (e.g., 4.1 or 3.8 volts). When you notice a significantly lower reading in a particular cell, that cell is the problem.
There can also be visible signs of battery damage that you can observe with the naked eye, such as the presence of black substances or cuts on the battery casing.
Note: Replacing battery cells requires specialized equipment to ensure the proper functioning of the battery, so it is best to have it done by a professional.
Don't worry, the cost will be minimal since you have already done all the work and identified the defect. All you need is to connect a new battery cell. You won't have to spend too much!
3. Wire Disconnection
The final major cause of battery failure is the presence of cut or disconnected wires inside the battery, whether it's in the main wiring of the battery or in the wires connected to the battery. This will result in the battery ceasing to function.
Usually, this issue occurs due to the battery being dropped or impacted on the ground. If you take good care of your electric bike's battery, you'll be safe from this.
To address this problem, simply remove the outer cover of the battery, locate the cut wires, and reconnect them.
Then, using a voltmeter, measure the voltage of the battery. If you find that the voltage reading is equal to the capacity of the same number of cells, you can determine the battery capacity using this formula (number of cells * 4.2 volts).
Connect the battery to a power source to ensure proper charging, and then close the battery cover.
4. Loose Battery Connection
When the battery is connected to the electric bike, it can cause damage or breakage to the battery pins, resulting in the battery ceasing to function.
You can visually inspect the pins to determine if the issue lies there, and in most cases, the battery will not be properly installed on the bike.
To address this issue, you can try modifying the pins using a screwdriver, but make sure to turn off the battery first.
Alternatively, you can replace the damaged parts within the battery entirely.
5. Charger Malfunction
The reason you are unable to use the battery may be due to a faulty charger rather than a problem with the battery itself. To determine if the issue is with the battery, try charging it with another charger or test the charger itself.
You can refer to this article, which provides detailed explanations on how to test an electric bike battery charger.
Conclusion
In general, electric bike batteries can be repaired by replacing internal cells, the BMS board, or fixing internal wiring.
One of the most significant issues that can occur with electric bike batteries is BMS damage, internal cell damage, or internal wire disconnection. Lastly, the battery pins may be damaged due to improper removal of the battery.
