How to Choose Your e-Bike Battery

Posted on May 29, 2019

Wondering how to choose the right e-bike battery that best serves your purpose?

Electric bike batteries are an essential component and make a huge difference to the performance of your e-bike. However, with the ever-evolving battery technology, you may find it difficult to choose the right one. There are a lot of factors to consider to get a battery that offers reliability and longevity. We wish to simplify it for you and this guide offers a thorough explanation of the variables that you need to reflect on when buying a battery.

Types of Batteries

To begin with, let us explore the different types of batteries available.

Sealed Lead-acid

These are the cheapest batteries available and have been in existence for over 100 years. The batteries can be recycled easily and this makes them the ideal option when you have a limited budget and are building your own bike.

However, there are limitations associated with these batteries. Not only are they very heavy, but they also do not last long. Moreover, they are highly susceptible to weather changes as compared to the other batteries available in the market.

Nickel Batteries

With new and better-performing batteries available, nickel batteries do not enjoy the same level of popularity as they earlier did. The fact that they are poor in terms of recyclability and are a dangerous pollutant makes them less favoured.

Lithium-ion Batteries

A game changer in the e-bike industry, lithium-ion batteries are known for their impressive ability to generate power. These batteries have the capacity to withstand high and low temperature easily. There are different variations of lithium batteries available like Lithium Cobalt, Lithium Phosphate, Lithium Manganese. A downside associated with these batteries is that they are not completely stable and much more expensive than the other batteries.

Technical Considerations:

When choosing a battery, it is also important to know the kind of motor you have and the power required along with an assessment of the following factors:

  • The voltage that you will find listed for a battery implies the amount that runs out of the battery. There is fluctuation in this for bursts of speed.

  • Amp hours refers to the duration for which the battery can supply a consistent flow of current. The higher the amp hours a battery has, the better.

  • A battery with a good power density offers a good power-to-weight ratio. A battery that has a good energy density ensures that you get great power for the little weight.

  • Replacing a battery is expensive, so it is best to go for a stable battery that allows you to save in the long run. In terms of reliability and stability, SLA batteries are a better option.

Maximising Range:

The most vital outcome that you want from a battery is a good range. This refers to the distance that can be travelled on a single charge and is affected by a number of factors. The higher the battery capacity, the more you can expect to go on a single charge.

  • To ensure that your battery is not drained, the tyres need to be pumped up well for maximum battery efficiency.

  • To get the best speed to range possible, it is essential to maintain the right speed. Travelling around 15 miles per hour is perfect.

  • Acceleration also has an impact on the performance of your battery. It strains the battery resulting in the battery depleting faster.

By having an understanding of the above variables, you can pick a battery that offers optimum performance and best suits your needs.
