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

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.

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!

Your electric bicycle battery is quite expensive. Understanding how to charge and maintain it correctly can extend its lifespan by 2 to 3 times. There are also some things to avoid that can significantly shorten the battery's lifespan. This article will tell you:



What to do when your battery is new

Basic electric bicycle battery charging guide

How to store it when you're not riding for a while

Lithium-ion batteries and safety

How to prolong battery lifespan

Charging with a "smart charger"



These guidelines and instructions assume that you purchased the battery together with the motor or electric bicycle, and their power and charging capacities are matched accordingly.




If you purchased them separately, you will need to learn more information to ensure you have the correct battery and there are no potentially dangerous combinations. Ideally, the battery should provide more capacity than the motor requires, and the charging speed should be faster than the charger's charging speed. Both have room to spare, so your battery won't be stressed, making it safer and prolonging its lifespan.



Lithium-ion batteries require minimal maintenance. The battery's longest range is achieved when it is charged between 30% and 80% capacity. Unlike other chemistries, lithium-ion batteries do not have a memory effect and can be topped up as needed.



When your battery is new:


Before use, it is recommended to fully charge the battery. For the initial charge, you should charge the battery to 100%. If time permits, leave it on the charger for about 12 hours to ensure an even distribution of battery charge. Afterward, if you have a smart charger, you can charge it to 80% or 90% to extend battery lifespan. Then, every few months or so, perform a full 12-hour charge after a deep discharge to recalibrate the battery.



Basic electric bicycle battery charging guide:


The battery can be charged on or off the bicycle.

First, plug the charger into an AC power outlet. If there is a switch, turn it on and then off. This charges the internal capacitors of the charger and prevents a surge current to the battery.

Next, plug the charger into the charging port of the battery, and if there is a switch, turn it on. Most chargers have a set of LED lights. One of them will be red during charging and turn green when the battery is fully charged. When the indicator light turns green, the charger is not charging the battery and should be disconnected.



Ensure that the battery is not near flammable materials during charging.

For Electrify Bike Co batteries with switches, turn them on before charging.

Disconnect the charger when the green light is illuminated.

Charge the battery when the remaining capacity is between 30% and 60%.

Partial charging extends battery lifespan more than full charging.

Do not charge below freezing or above 50°C (120°F).

Perform a 100% charge every 1-3 months.



Storing Your Lithium-Ion Electric Bicycle Battery


When you are not riding your electric bicycle temporarily, there are two crucial things to consider when storing the battery: the charge percentage and the temperature. If you plan to store the battery for more than a few weeks, you should set its charge level between 40% and 70%. Do not store the battery at 100% charge as it will shorten its overall lifespan. Additionally, avoid storing the battery with a charge level below 40% as the capacity may degrade over time. If it falls below its low-voltage limit (around 2.6-2.8 volts per cell), it may become permanently damaged and might not be rechargeable thereafter.



During long-term storage, it is advisable to periodically check the voltage and recharge it to above 50% as needed. This frequency can range from every 3 to 6 months.



Keep the battery at a moderate temperature. Lithium-ion batteries that are partially charged tend to have a longer lifespan when stored in a cool place. The worst combination is high voltage (100%) and high temperature. For long-term storage (several months or longer), store the lithium-ion battery at approximately 50% charge. Ensure that you do not leave the battery in a place where the temperature may rise above 120 degrees Fahrenheit for an extended period, such as a closed vehicle or a building without climate control.



If the temperature drops below 32 degrees Fahrenheit (0°C), do not charge the battery, as it may be damaged. Place the battery indoors and allow it to warm up before charging. Discharging the battery (riding the bicycle) is possible in cold weather, but it will reduce your range. However, it will not harm your battery or shorten its lifespan. Conversely, if the temperature exceeds 120 degrees Fahrenheit, do not charge the battery, as it may also be damaged.



Lithium-Ion Batteries and Safety


Lithium-ion batteries can pose a fire hazard. This risk is significantly reduced if you purchase high-quality batteries from reputable sources that use branded cells. However, the risk increases if any cells within the battery are damaged due to drops or exceeding charging/discharging limits. Do not leave charging batteries unattended, and avoid charging them near flammable materials. If the battery is visibly damaged due to drops or water exposure, it should be recycled and replaced.



Failure to charge lithium-ion batteries in accordance with the following guidelines can shorten their lifespan and pose significant safety hazards.



Lithium-ion Battery Charging Temperature:

0°C to 45°C (32°F to 113°F)



Lithium-ion Battery Discharging Temperature:

–20°C to 60°C (–4°F to 140°F)



Extreme Temperature Guidelines:

Charge at reduced current below 41°F.

Charging below freezing is not permitted.

Good charging and discharging performance at higher temperatures but with a shorter lifespan.



Extending Battery Lifespan


Lithium-ion batteries, unlike some other technologies, do not have a memory effect, so you can charge them at any time without fully discharging them. When charged to 100%, it is expected to go through about 300-400 full charge cycles before the battery capacity drops to 80% of its original capacity. In terms of range, this means that if your new battery can travel 20 miles at 80% capacity, it will only travel 16 miles after 300-400 full charge cycles.



The simplest way to extend battery lifespan is to only charge it to 80% or 90% when you won't be riding for a few days. Most recreational rides don't require a full charge anyway. Doing so can extend the battery's lifespan by 2 to 4 times. Charging to 90% will give you around 1000 charge cycles, while charging to 80% will give you around 1600 charge cycles. This is similar to how you treat your smartphone. After charging it every day for a year, you'll notice that its talk or screen time is only 80% of what it used to be.



If you know you're going on a long ride and want to ensure the battery has enough charge, feel free to charge it to 100%. Doing so before a ride won't shorten the battery's lifespan. To control charging at 80% or 90%, you would need an "advanced" or "smart" charger that has this feature. Most chargers that come with electric bicycles do not have this capability.



If you use a smart charger to extend battery lifespan by charging to 80% or 90%, you should occasionally (every 2-4 months) balance the battery. To do this, you'll need to perform a deep discharge (below 30%) and then charge the battery to 100% to give the battery management system (BMS) a chance to rebalance the battery for maximum capacity.



Subjecting the battery to high drains will shorten its lifespan. If your battery is rated for a continuous power of 40 amps, it doesn't necessarily mean you should run it at that power for extended periods. If your battery feels hot to the touch during use, it may indicate that you're drawing too much current for too long. The BMS of the battery may allow you to draw more current when needed, but you should be aware that it should not be abused.



Avoid charging the battery too quickly or too frequently. Just like electric cars with fast-charging stations, you can also fast-charge electric bicycles. Electric car manufacturers warn against relying solely on fast-charging stations as it can shorten the lifespan of the car battery. Unlike fast chargers for cars, most electric bicycle fast chargers operate within the safe charging limits of the battery and do not shorten its lifespan, unless you have found and purchased an ultra-fast charger.



For example, all the batteries used by Electrify Bike Co. can be charged at 1.5 amps without decreasing the battery lifespan. Our popular battery, the Super Shark, consists of 14 series cells and 4 parallel cells. Four times 1.5 amps equals 6 amps, so the charger can charge at a current of 6 amps without reducing the battery lifespan. Our fastest chargers are only four and five amps, which is two-thirds of the safe charging level. Each battery also has a safe fast-charging rating, but frequent use may decrease the battery lifespan. This rating is approximately 2.5 amps per cell, so a 4P battery has a rated current of 10 amps. Even the Electrify Bike 2P Mini-Max battery can handle a 5-amp charge without reducing the battery lifespan. This is one of the many advantages of using high-quality batteries in battery manufacturing.






Using "smart chargers" for charging


Smart chargers can automatically stop charging when the battery reaches 80%, 90%, or 100% capacity. This can be selected using a rotary switch at the end of the charger. Electrify Bike Company offers smart chargers in 2-amp and 4-amp sizes, suitable for 36V, 48V, 52V, and 72V batteries. We also provide advanced smart chargers with the same voltages and an additional rotary switch to select 1 to 5 amps. The advanced smart chargers also feature a display screen with switches to show voltage and current.



The recommended way to use a smart charger is to charge to 90% after each ride, so your bike is always ready to go. Then, if you're planning an extended ride and want to ensure maximum battery range, you can charge it to 100%. Charging the battery to 100% before a ride will not have a negative impact on battery lifespan.
