Ebike batteries are crucial to the functionality of your bike. It determines how long the bike will work, its speed, and the weight of the ebike. The more powerful the ebike battery, the more efficient the electric bike is.
Various batteries are compatible with different electric bikes. However, most manufacturers prefer lithium ion batteries for ebike. Lithium batteries are renowned for their high energy density and long lifespan. This guarantees a more extended ride period for bikes powered by lithium batteries. Additionally, riders are assured that they can recharge their batteries more times than regular batteries without the need to get new ones.
There are different variations of Lithium battery for ebikes. Of the different types, five are more popular. These 5 include Lithium Ion Battery, Lithium Manganese, Lithium Cobalt, Lithium Ion Phosphate, and Lithium Ion Phosphate. The different variations of Lithium ion batteries have their respective strengths.
In the ebike world, the Lithium ion battery is usually preferred because of its high capacity. However, it is more temperature sensitive than its counterparts. In terms of temperature durability, Lithium Iron Phosphate is quite impressive. It has frost resistance, enabling it to go through different temperatures without losing charge.
If you need your battery to be safe from overcharging, the Lithium Ion Polymer is your best fit. It doesn’t have liquid in it. Hence, making it a safe option. Currently, Lithium Cobalt has the highest density among the variants of Lithium batteries. Additionally, it has high durability, ensuring that the battery lasts long before the next recharge.
The benefits of using a lithium battery for ebikes
There are many advantages of using a Lithium ion battery for ebike. They are cost effective and more durable than their alkaline counterparts. Additionally, Lithium batteries improve your user experience by supplying adequate power to run your electric motor efficiently. Without taking much time, let's run through three crucial benefits of using a Lithium battery for ebike.
1. Lightweight And Compact
One significant advantage of using a Lithium ion battery for ebike is its size. Lithium batteries have a small size and can easily fit different types of battery frames. The simplicity in size is not limited to lower battery capacities. The large and mid-level lithium batteries are sizeable as well. This effect on your bike is that you enjoy a higher range and travel farther without fearing your bike stopping midway.
2. Long Lifespan And High Energy Density
Lithium batteries have a wider range than other battery types. On average, you can recharge most Lithium batteries as much as 500 times. Coupled with this, they have very high densities. The implication of this is that they store charges for an extended period of time. This impacts how far and how fast your ebike can travel.
3. Low Self-Discharge Rate And Wide Temperature Range
Most batteries do not perform well in extreme conditions. For example, alkaline batteries drain faster whenever the temperature is low. This is because alkaline batteries make use of water-based electrolytes. When the weather temperature is low, it slows down the ion mobility of the electrolytes in these batteries. Consequently, the performance of the alkaline batteries gets slowed down.
On the other hand, Lithium batteries perform excellently well in this regard. They function maximally in both high and low temperatures. Hence, giving you the confidence to ride outdoors during the snow and harsh weather conditions.
It is common for ebike batteries to discharge when not in use. For some battery brands, the discharge rate is as high as 50% per month. However, Lithium batteries have a reasonable discharge rate of about 5% per month. Due to the discharge rate of ebike batteries, you should charge the battery before storing away the ebike for a long time.
How Lithium Batteries Can Improve The Ebike Experience
1. Increased Range And Performance
It would not be wrong to tag the battery of an ebike as the heartbeat of your ebike. Batteries power the electric motor, which is the most vital part of the ebike. Lithium batteries have a wide range enabling you to charge them as much as 500 times. Their range is coupled with superb battery density, ensuring the battery retains charges for a long time.
The range of Lithium batteries enables you to cover longer distances without fearing your battery running down. Lithium batteries give you a smooth ride under challenging terrains. This is because they can supply the high power demand to the ebike motors in such landscapes.
Lithium batteries do not have memory retention, so you are guaranteed long term usage if your battery is managed correctly.
2. Improved Portability And Convenience
One factor many people look out for in ebikes is speed. However, several factors play a significant role in the speed of an ebike. One such factor is the weight of the ebike. The weight of the ebike is usually influenced by factors like the electric motor, bike frame, and the ebike battery.
Most Lithium ion batteries for ebike are lightweight and compact. Hence reducing the amount of weight on the ebike. This reduction in weight aids maneuverability and speed. Additionally, the compact nature of lithium batteries enables you to place them anywhere on your bike without them protruding or affecting anything.
3. Enhanced Sustainability And Environmental Impact
Using a Lithium ion battery for ebike would considerably reduce your carbon footprint and benefit the environment. Simply put, your carbon footprint is the cumulative amount of carbon you emit into the atmosphere due to your lifestyle and practices.
Lithium batteries are reusable. As such, they would be up and running once you charge them. Additionally, they are efficient and durable. Lithium batteries have a longer lifespan than most ebike batteries. While they may be a bit more expensive to purchase, they save you more cost in the long run. This is because you would not need to replace a lithium battery as frequently as other ebike batteries.
Furthermore, Lithium batteries do not contain harmful chemicals like Lead and Cadmium. Due to this, they would not be a threat to the environment when you eventually need to dispose of them.
Considerations When Choosing A Lithium Ion Battery For Your Ebike
When getting a lithium ion battery for ebike, it is essential to consider the following factors:
1. Compatibility With Your Ebike
You need to pay attention to how compatible the lithium battery is with your ebike. One compatibility test you should consider is the weight of the battery. Different batteries have different weights. If you are not a fan of heavy gadgets, you should choose lightweight ebike batteries. This will save you the stress of a purchase you would keep grumbling about.
It is also essential to consider the battery weight because of your ebike frame. Ebike frames have varying strengths. Using a heavy battery for a lightweight ebike frame could be an easy route to destroying the ebike.
2. Capacity And Voltage
The battery capacity of an ebike is an indicator of the energy rating of the battery. A higher capacity means more range. A battery's range is the total distance it can travel with one full charge. By implication, a higher range means the battery can travel farther with one charge. For most batteries, the entire battery range cannot be used by the ebike. Hence, it is essential to take note of the depth of discharge the battery has. For example, a 100 ampere-hour Li-ion battery having a DoD of 0.78 means only a 78 ampere-hour charge of the battery can be used.
You should also look out for the Lithium battery's Voltage for Ebike. Every ebike comes with its distinct input volt range. Using a battery voltage that is higher or lower will harm the bike. A voltage higher than the recommended Voltage would damage the electrical components of the motor. On the other hand, using a lower voltage than that specified would not be sufficient to power the ebike motor.
3. Brand And Warranty
Lithium batteries have a good reputation. However, how well different batteries perform could be affected by the manufacturer of such batteries. Due to this, it is best to buy a Lithium battery from a reputable battery manufacturer. While making your purchase, watch out for the warranty as well. Warranties say a lot about the kind of confidence manufacturers have in their products. Most especially if you will be buying from a not so famous brand. Ensure you pay attention to the attached terms and conditions to make the most of the warranty.
