36V vs 48V E-Bike Battery, Which One Is The Best?

If you're in the market for a new e-bike, you may be wondering whether you should choose a 36V or 48V battery. Both options have their pros and cons, so it can be difficult to decide which one is right for you. In this article, we will compare and contrast 36V and 48V batteries and help you decide which option is best for your needs.

1. What you need to know about e-bike batteries

When you want to choose a battery, you should understand the factors that make up the battery.


Battery capacity is in Amp-hours or Ah. Amp-hours corresponds to the measure of current the battery can deliver in one hour at a usable voltage or the measure of capacity your battery has. In short, the higher the amp-hour number, the farther you can drive.

Voltage of the battery

The voltage of a battery is its ability to provide current. A battery with a higher voltage will provide more power to the electric bicycle. A 36V electric bicycle battery has a lower current, usually around 15 amps, while a 48V electric bicycle battery will allow a higher current, ranging from 10-40 amps. This means that an electric bike with a 48V battery will go faster. Therefore, a 36V e-bike battery will require you to use more muscle power to reach the same speed.


This is a parameter you will more often see on electric bikes and should play a key role in determining an electric bike battery.

Watts = Volts x Amperes

When you multiply the battery voltage by its given amperage, you get watts. This is the maximum wattage that the e-bike battery can handle. In watt-hours, it shows how many watts an e-bike battery can deliver in an hour.

The above three factors are what you must go through when buying a battery, which determine the power and range of the battery.

2. What is a 36V battery and what is a 48V battery?

A 36V battery is a lithium ion battery that has a voltage of 36 volts. A 48V battery is also a lithium ion battery, but it has a voltage of 48 volts.

Both types of batteries are used in electric bicycles, but the difference in voltage means that they provide different amounts of power. A 36V battery will provide less power than a 48V battery. However, the 36V battery is typically smaller and lighter than the 48V battery, making it a good option for those who are looking for a lightweight e-bike.

If you're looking for an e-bike with more power, then you'll want to choose a 48V battery. However, keep in mind that the 48V battery is also heavier than the 36V battery, so it may not be ideal for those who are looking for a lightweight option.

3. How do 36V batteries and 48V batteries compare in terms of performance and price?

When it comes to performance, the 48V battery is going to be the better option. It provides more power and will therefore give you a smoother ride. However, the 36V battery is still a good choice for those who are looking for a lightweight e-bike.

In terms of price, the 48V battery is going to be more expensive than the 36V battery. However, it's important to keep in mind that the 48V battery will also last longer than the 36V battery. So, if you're looking for an e-bike that will give you a long-lasting ride, then you'll want to choose the 48V battery.

4. So, which is better, a 36v or 48v battery?

You may think that by the above reasoning, the 48V battery would be the best e-bike battery because it offers more power and riding range. But the answer is complicated, and instead of focusing on which electric bicycle battery is the best, let's think about which battery will best meet your needs. Let's consider the various factors that should determine which is the best e-bike battery for you.


A flat surface requires less power to accelerate. Whereas areas such as hills and mountains require more power, such terrain will provide resistance. If you are light, a 36V e-bike battery may be able to provide enough capacity to climb. But on windy days, you'll feel more resistance, and on top of that, you'll drain the battery's power faster, affecting its life and efficiency. That's why 48V e-bike batteries are better suited for areas of higher resistance such as hills and mountains. For one thing, they give you far more critical current than a 36V e-bike battery. But 48v batteries cost more and are heavier, but it's worth investing in a 48v battery if you spend a lot of time in high resistance areas .


To decide which battery is best for you, your weight is an important consideration. For people who weigh 250 pounds or more, the battery considerations are exponential. For example, you want to run an errand on your electric bike in a mostly flat area. And you weigh about 100 pounds. You might use a combination of power assist and pedals to make a quick round trip at a comfortable 400 watts per hour. Look at it this way, your 36V electric bike battery can take you 20-40 miles on a single charge. Your weight and the weight you carry on the bike will determine whether it goes 20 miles or 40 miles. If you add a stroller for your kids or your pets while riding, you'll have to consider whether a 36v battery will allow you to ride smoothly when the weight increases.


The controller regulates the power of your electric bike. If your controller has a lower power rating than your battery, it releases less current, so no matter how much you accelerate the auxiliary controls or battery voltage it will not go too fast. However, using a controller with a higher power rating can cause you to draw more current than you ideally want, which can lead to overheating. So ideally, you should use a controller with the same power rating as your battery. This combination will minimize your battery losses.

5. Summary

Are you looking for an electric bike to enjoy your riding experience and use power assist intermittently? Well, a 36V e-bike battery is perfectly capable of doing just that, as long as you are within a certain weight range and the terrain you are traveling on is more or less smooth. However, a 48V e-bike battery will give you faster speeds and longer riding range. In addition, if you wish to explore nature with your electric bike and the roads are usually rough and resistive, and you need to take into account your own weight and the weight you carry, then a 48V e-bike or maybe more suitable for you.

Regarding the question "which e-bike battery is best, 36V or 48V", our final conclusion is that this is relative to the user and both batteries have their advantages and disadvantages. 36V e-bike batteries are relatively cheaper and a good choice for those who want to enjoy the riding experience on flat ground. 48V e-bike batteries are relatively more costly. But if you need more power, it's worth the choice. Of course, the final choice needs to be considered by you according to the actual situation.
