With climate change getting worse, electric bikes offer an eco-friendly, economically viable mode of transportation. The transportation phenomenon has changed significantly since e-bikes were introduced. These bikes are more convenient, safe, and viable than any traditional means of transportation.

Although they are getting attention from almost all sectors, some people still ask why electric bikes instead of traditional ones. Since they feature a battery-powered motor, electric bikes provide pedal assistance, which makes them easier for anyone to ride and makes traveling more convenient.

To generate power for this assistance, electric bikes use renewable rechargeable batteries instead of burning fossil fuels. Therefore, the batteries used in electric bikes are of vital importance and need more consideration.

In this blog, we'll talk about one of the most in-demand types of batteries for electric bikes and why you should use them instead of normal batteries. Let's get started.

What is 18650 battery?

Let's start at the bottom. To understand these batteries better, let's first understand their basics. The 18650 battery is a common type of lithium-ion battery that is used in a wide range of high-drain devices, such as electric vehicles. The name is derived from their physical dimensions, which are 18mm in diameter and 65mm in height. Batteries have cylindrical shapes, so the zero at the end of the name represents that.

Thanks to their reliable attributes, 18650 batteries can be used in a variety of devices, including laptops, power banks, flashlights, and light electric vehicles. The batteries have a high energy density, a long run time, a low self-discharge rate, and a long lifespan, which makes them ideal for electric tricycles and bicycles.
In recent years, these electric batteries have become more and more popular and they are available in many variants. The fundamental difference between these variants is the capacity and discharge rate of the battery.

Batteries are measured by their milliampere-hour capacity (mAh). mAh ratings indicate how much energy can be stored in a battery. Batteries with a higher mAh capacity can store more energy. More energy means more runtime for your device. Likewise, a higher-capacity battery will take longer to charge as well. Currently, 18650 batteries have different capacities including 2600mAh, 2900mAh, 3200mAh, and 3500mAh.

Which 18650 battery variant provides the best performance?

In the midst of so many options, you may be wondering which will work best for you. Well, don't worry, we are here to provide you with enough information to make the right choice and never delay your rides.

Since different variants offer different capacities, you'll want to choose the most powerful capacity of a 18650 battery for your device so that it can last longer. However, there's another factor to consider as well while choosing among these variants and that is the continuous discharge rate. In general, higher-capacity batteries have lower discharge currents than lower-capacity batteries.

If your device, such as an electric tricycle, requires heavy current input, you'll have no choice but to select one with a higher discharge rate. It is expected that a battery with a high discharge rate will have better temperature stability and tolerance than one with a lower discharge rate. Also, a lower mAh battery can handle a higher input current draw than a higher mAh one.

So, with a lower mAh, your e tricycle might not last as long as you want it but it will be able to deliver enough current. With higher mAh, there are also chances of voltage drops and overheating.

After considering these two factors, the 2900mAh battery among the discussed variants is the most balanced one and will provide the most efficient performance. It offers enough capacity and has a stable discharge rate, which is ideal for an electric bike.

One more thing that you should take into consideration is the brand you are sticking with. Your battery manufacturing company matters, because a battery with less capacity might not be rated for much current, and on the other hand a high-capacity battery can deliver significant current. In the next section, we will compare some of the top battery manufacturing brands for you.
