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!
Electric bicycles can vary significantly in terms of battery life and charging time. In fact, this is one of the first things you need to know after purchasing an electric bike: how long does it take to charge?
What to consider when charging an electric bike for the first time?
The charging time for an electric bike battery depends on its capacity, which you can find in the manual. Please note that the initial charging time for a new electric bike will be longer than usual. It is also important to only use the certified charger that comes with the electric bike and avoid using non-original chargers. Purchase chargers from the same manufacturer and do not attempt to use a lead charger to charge a lithium battery; they work on different algorithms.
How long does it take to charge an electric bike?
Typically, it takes 3-8 hours.
Ideally, you would charge the battery directly from a power source. Of course, you can charge the battery without removing it from the bike, but this can only be done when the motor is turned off.
Do not exceed the specified charging time mentioned in the user manual. Before storing the battery for an extended period, it must be charged to 100% and then charged at least every 2-3 months.
In essence, the charging time for an electric bike depends on various factors, with a minimum time of three hours. Charging an electric bike battery to full capacity takes longer.
Let's dive deeper into it.
How far can an electric bike go on a single charge?
As mentioned, the answer to this question largely depends on the type of battery, your riding style, and the level of electric assistance. So, the range on a single charge is a broad question. Most electric bikes have a range of 22 to 50 miles, and in some cases, the range may be even longer. These values can be achieved by simply pedaling the bike, as the more physical effort you put in, the more range you'll get. With a good electric bike and consistent pedaling, you can travel approximately 80 miles. But guess what? With an extra battery, you can go even longer.
Tips for extending battery life
The key to ensuring a longer lifespan for your electric bike lies in economically utilizing its power resources. Here are some tips that can help prolong the battery's usage:
Accelerate smoothly and avoid "flooring" the throttle from a standstill. Assist the electric bike's acceleration by pedaling. Even a few rotations of the pedals can lighten the load on the motor wheel. Additionally, pedaling during acceleration can save battery and increase the duration of the autonomous drive.
Pedal during uphill climbs.
Avoid excessive reliance on the motor's power.
Do not connect third-party devices such as phones or tablets to the battery. Only charge accessories that are specifically designed for the electric bike.
Opt for a gentle riding style, avoiding sudden movements and abrupt braking. Low speeds require less power, while acceleration increases the mechanical work required by the motor. This increases the battery's current consumption. Measured movements enhance both the range of the electric bike and user safety.
Monitor the battery's charge level and the functioning of electrical components.
Pay attention to the condition of the tires and inflate them to the recommended pressure. Deflated tires significantly reduce the range on a single charge, so regular checks of tire wear are necessary. Poor tire condition makes riding more difficult.
Minimize the load on the wheels. The weight of transported items should not exceed the electric bike's carrying capacity.
Adopt a low, aerodynamically efficient riding position used by sports cyclists when in motion. This reduces air resistance and promotes speed. This means less stress on the battery.
Basically, properly maintaining an electric bike will significantly extend the battery's lifespan and increase the number of charging cycles.
Conclusion
The actual range of an electric bike depends on several parameters: the user's weight, speed of movement, pedaling, frequency of acceleration and deceleration, characteristics of the road surface, and the quality of the electric bike itself.
We hope this article clearly explains how long it takes to charge an electric bike battery. If the charging and storage guidelines are followed, the range on a single charge of an electric bike will only slightly decrease over the years, meaning you won't need to purchase a new battery for a long time.
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.
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.
