Electric Bike Battery Specifications you Should Know

When it comes to e-bikes, the battery is one of the most important parts of your new ride. This essential part powers your electric bike and helps you go further and faster. In this article, we’ll be looking at e-bike battery specifications.

After reading this, you won’t be green when you see numbers attached to your bike battery pack.

What is a battery pack?

A battery pack is a term used to describe the overall collection of individual batteries that are used inside your electric bike.

The battery pack is the core unit of your electric bike and it contains all the batteries used for powering your e-bike. The battery pack is also known as a power pack or system, and you’ll also find it referred to as a “battery pack”, “motor”, “drive system” or “motor unit” on most electric bikes.

What are batteries?

Batteries are rechargeable lithium-ion cells and they contain an electrolyte-like substance that conducts electricity from one end to another. The cells can be either nickel cadmium (NiCd) or lithium-ion (Li-ion).

They are usually made up of several cells in series with each cell being connected via a diode bridge circuit so that they function together as one single cell. The voltage of a single cell is between 1.2V and 2V while a group of four cells will produce 12V when charged up.

Battery Pack Specifications

Now let’s dive straight into the technical specs of a battery pack:


Voltage is measured in volts (V) and voltage will tell you how much power your batteries can produce when they are charged up to their maximum capacity. It tells you whether your bike has enough power to ride fast or slow, as well as if you need to upgrade/upgrade your batteries before riding long distances on them or not.

Voltage also tells you whether or not you need to worry about overcharging/overheating your batteries if you do not have enough experience with them yet or not.

You don’t want to overcharge/overheat them because it will shorten their lifespan and cause them to lose their ability to hold that much energy inside


Ah is short for Ampere Hour and it’s a unit used to describe how long a battery pack can power your electric bike. The higher the Ah, the longer your e-bike will run on one charge. For example, a battery pack may have 10Ah. This means that for every hour of riding time, the pack can deliver 10 Ah of power.

We can compare amp hours to a vehicle’s gas tank. So, the more amp hours you have, the more range you will cover with your bike.

Most battery packs in the market are rated 10Ah,13Ah, and 15Ah.


The weight of the battery pack is measured in pounds (lbs) or kilograms (kg). Weight is important because it affects how quickly you can get up to speed on your e-bike while also affecting your balance and comfort when riding uphill or downhill at high speeds with heavy packs on your back! A heavier battery will also cost more money to ship since it’s much heavier than lighter batteries.


Watts= Volts *Amps. Or simplified as Force *Volume. This is to say that the watts of a battery pack is the measure of its real power. If a battery is rated 10A and 36V, then its power is 360 watts.

Max Amp Hours (MAh)

This is another way of measuring how much electrical energy your battery pack will deliver to your e-bike when fully charged. It’s measured in amp hours and is usually given in Ah and usually ranges between 25% and 50% higher than Ah ratings of individual cells.

For instance, a 48V battery pack with 75Ah rating means that it can deliver up to 50Ah when fully charged (75 x 1.25 = 100Ah). A 48V pack with only 50Ah rating would only be able to deliver up to half that amount at 25Ah per charge (50 x 1/2 = 25). This is because we’re making use of an average voltage across all cells in this case so we don’t get accurate numbers for each cell individually.


So, are you ready to buy the battery pack for your ebike? That is going to be a very smooth process. Just use the following battery pack guide to help you. It will take you through the whole process and make sure that you get a good, reliable pack.
