Our Ebike Kit Batteries Explained

electric bike battery for ebike conversion systems

Ebike batteries are one of the core components of an electric bike. Without a good battery, you’re not going to enjoy the e-biking experience. E-bike battery technology has been evolving rapidly over the last few years, so knowing what type of battery is best in terms of battery life and performance can be quite challenging. With different types of e-bike kits and battery packs in the market, it’s not always easy to make the right purchase.

As the number of ebikes has increased and the industry has matured, the development of ebike batteries has also increased. To understand how electric bike batteries work, we’re going to look at how they work, their capacity, how far they can go on a full charge, choosing the right type, how they are placed on an e-bike and how to get the most out of your electric bike battery.

What are E-bike Batteries Made of?

Electric bike batteries come in the form of packs. A park is basically made of a number of smaller battery cells that are usually stacked up in a specific way so as to deliver the required power that your ebike system needs to function as expected. It’s important to pick the right battery park for your application. There are different types of ebike batteries available to choose from.

Battery Capacity

Electric bike capacity is usually measured in Amp hours (Ah) or Watt-hours(Wh). While both are basically measuring the same thing, Watt-hours is considered as the standard because it’s a bit more consumer-friendly. Electric bike batteries come with a range of capacities. Considering that the battery is usually the most expensive part of an e-bike to produce, the cheapest bikes in the market tend to come with smaller batteries.

Ebike battery capacities can range from 150 to 200 Watt-hours in the smaller range to 300 to 500 Watt-hours in the standard range, and up to 900 Watt-hours in the higher range. As more progressive innovations are being made to increase battery capacity, we’re seeing more companies coming up with bigger ebike batteries or even announcing dual-battery systems offering up to 1000 Watt-hours(2×500 Wh batteries).

Choosing the Right Type of E-bike Battery

Types of ebike batteries

In the world of e-bike kit batteries, there are different options to choose from. These include:

  • Lead-acid e-bike batteries – Mostly found on cheap electric bikes
  • Nickel-cadmium e-bike batteries – Expensive, hard to recycle and last longer
  • Nickel-metal e-bike hydride batteries
  • Lithium-ion e-bike batteries – Most widely used batteries in the ebike market
  • Lithium-ion polymer e-bike batteries – Promise to be better than lithium-ion batteries in terms of range, price and weight
  • Lithium cobalt e-bike batteries – Relatively new in the market with claims of higher energy density than other Lithium batteries
  • Lithium manganese e-bike batteries – Claimed to be the best of all in the coming future

In short, the right choice is some kind of Lithium-ion battery, although there is still debate on which one is the best in this category. If the electric bike you’re buying comes with a Lithium-ion battery, you’re off on the right track. Beyond that, it’s important to weigh your options when it comes to ebike battery range, safety, high energy density, shape and performance.

How Far Can an E-Bike Battery Go on Full Charge?

Range estimates can be a bit confusing, especially when you visit different electric bike companies and ebike review sites. The truth is, range depends on the power of your electric bike battery, the bike’s battery management system, the power of the bike and the way you ride. Of course, some electric bikes allow you to choose from different types and levels of pedal assist so as to prioritize speed or battery life, potentially extending battery range.

You can expect anywhere between 25 and 70 miles of riding on a single charge. If you are managing your battery life well, you could easily get more range, but if you are riding hard on full power, you should expect less. It’s important to understand how your electric bike works so that you can have a pretty good idea of how to use ebike batteries for extended use.

Where are E-Bike Batteries Placed?

Ebike battery placement

Electric bike battery placement depends on different factors, especially the shape of your bike’s frame. The majority of urban or electric city bikes will have their battery mounted on the rear carrier rack, while most mountain bikes usually have their batteries placed on the downtube. Depending on your riding style and bike choice, battery placement inside the frame and between the wheels is the most ideal for the best possible ride comfort and weight contribution.

Saddlebag or rear rack battery placement is a good option if you’re looking for an easy and convenient placement method. Ebike batteries can come with mounting brackets that make mounting on the bike easy and with protective cases that protect the battery from any impacts.

How to Get the Most Out of Your E-Bike Battery

No matter the type of electric bike battery you have, there’s one golden rule to keep in mind if you want to get the most out of your battery: Keep it topped up. This is true with Lithium-ion batteries. The best way to prolong the life of your electric bike battery is to charge it as often as you can. It’s good to have a spare charger at your workplace if you can.

Experts agree that the best way to improve the lifetime and performance of an ebike Lithium battery is actually to reduce the number of deep discharge cycles as much as you can. Another tip to keep in mind is to ensure that your battery is regularly exercised during the winter or any other time that you’re not using your ebike. Charging your e-bike kit battery at least for 30 minutes a week will save your battery from damage.

Buying the Right Ebike Batteries

When it comes to buying electric bike batteries, you need to determine your needs. If you’ll be going for multiple rides a day, like running some small errands, you may need a small battery pack that costs less, is lighter and far more enjoyable to ride, and can easily be charged quickly while providing the range that you need on a single charge.

However, if your needs are more complicated than that, such as hauling some groceries or a backpack for a weekend hiking or mountaineering trip, you’ll obviously need a bigger battery, a bigger motor and a stronger bike. Larger battery capacities are available and will help you get the job done. In most cases, a lightweight bike with a standard battery capacity is ideal for day-to-day e-bike riding needs.

Cost of E-Bike Batteries

While the price of Lithium-ion batteries has been high in the past, the world’s supply of Lithium-ion batteries continues to ramp up, and this trend is set to continue, further driving down costs. With companies like Tesla building massive Lithium-ion battery production facilities, ebike customers are set to enjoy much lower prices over the next few years.
