If your e-bike’s battery is dead or you are looking for a backup, you surely are wondering if they are universal or interchangeable. Well, it’s not a one word answer. There are a number of things to carry on your mind when you are considering the final decision. To make things crystal clear for you, I pieced this guide so that you will know every bit of thing about e-bike batteries.
Are Ebike Batteries Universal?
Certainly, ebike batteries aren’t universal. We need to dive a little deeper to understand why aren’t e-bike batteries universal. The E-bike battery pack comes with different technical features such as Voltage, Ampere hour, Fitment size, Weight, and Controller. All of these are rated and balanced with the motor when it was built.
So, when you replace the battery with different specifications, your e-bike won’t move. In the worst case scenario, it might even be dead! So when you need to replace your battery you must replace it from the original manufacturer. But what if your manufacturer gets out of business? Well, that brings the next important question, are ebike batteries interchangeable? Take a break and let me dive deeper!
Are Ebike Batteries Interchangeable?
Likewise, you can’t really use any battery on your ebike. That solves our first problem, it’s not universal. But are they interchangeable? Yes and no! If you can find the exact same battery of yours from a different manufacturer, then it will do your job without any doubt! But you have to make sure these:
That brings out the next big question, can you increase the voltage of your battery for a faster ride?
Can You Put a 48 Volt Battery On A 36 Volt E-Bike?
Technically, you can Put a 48 Volt Battery On A 36 Volt E-Bike as long as your controller supports the higher voltage. You can easily check it by opening the controller box. If it says 63V in the main caps then you can use a 48V battery easily. However, if it says 50V then unfortunately you can’t keep a 48V battery.
Note that, if you increase the battery voltage, you will put the controller at risk. It may heat up consistently and even have the risk of being exploded! So think about it twice if it is worth the risk!
What About Non-Removable Frame Integrated Batteries?
Non-removable batteries are the oldest kind of batteries in the e-bike industry. However, there are tons of brands still producing the frame-integrated battery bikes as it is loved by so many riders. Let’s see their pros & cons shortly.
- Frame integrated battery bikes look more fabulous compared to the detachable one.
- These bikes are lighter than the portable battery bikes.
- You have to bring the whole bike in your house for charging.
Type of Batteries Used in eBikes
Over the time manufacturers tried to revolutionize the e-bike industry with different types of batteries. Not all of them worked out in the long run. Out of many only 3 types of batteries manufactured for a longer period of type.
In its early days, riders were fond of getting lead-acid batteries as it is a super durable and heavy battery. However, over time, it lost its fame when a new battery hit the market. Still, it is used on a very few bikes as it is super cheap. Besides, most of the toy cars and toy bikes are now manufactured with lead-acid batteries.
Made of nickel oxide hydroxide and metallic cadmium, the Ni-Cad battery is the 2nd cheapest option available in the market with an efficient usage capacity.
Lithium-ion battery is a widely used battery for not only ebikes but also for other electronic rechargeable devices. It charges way faster than other types of batteries and consumes very low power so that you will be saving on your electricity bill too. Despite that, the Li-ion is the most lightweight battery in e-bike history.

How To Find The Right Ebike Battery?
There are a number of factors that come into play when you want to choose among different batteries. Let’s take a closer look.
You have two options here to choose from. One- frame-integrated battery, two- detachable battery. Frame-integrated battery looks great but the detachable one provides more flexibility. While frame-integrated batteries are comparatively cheap and need the whole bike to carry for charging, the detachable battery is more expensive and you can just detach the battery and charge them anywhere you want.
Type of battery
Among different types of batteries such as Lead-acid Battery Nickel-cadmium Battery, the Lithium-ion Battery provides the most efficient performance.
Don’t forget to check how much the battery needs to be fully charged from battery level zero. The lowest, the better!
Distance & Budget
Depending on the distance and budget, choose the voltage of your battery. If you need to commute long distances daily then you need bigger voltage and bigger Ah. And bigger voltage and bigger Ah means bigger budget!
How Can I Replace My E-Bike Battery?
