BionX E-Bike Battery Replacement

AS OF AUGUST 2020, WE ARE NO LONGER REBUILDING BIONX BATTERIES DUE TO A HIGH NUMBER OF FAILURES OF THEIR BATTERY MANAGEMENT SYSTEM BOARDS WHICH WE CANNOT REPLACE. WE RECOMMEND CONTACTING OHM CYCLES OR BIONX LEGACY SHOP.

Do you have a BionX e-bike that needs a new battery? Let us rebuild, refurbish, and upgrade your old one! We can swap in fresh, grade A lithium ion cells to get you back on your wheels. We've squeezed in as much as 40V 13Ah in a rear rack case more than doubling the range of the original battery. We can take care of all form factors of BionX e-bike batteries whether it's the rear rack or down tube style.

Some of these larger downtube, triangular, fin-shaped batteries can hold up to 60 cells, giving them plenty of room to be upgraded to 36V 21Ah.

All of our batteries are warrantied for a full 12 months. All you need to do is fill out our Battery Intake Form and send us the battery, charger, and bike. We'll even recycle your old batteries for you! Don't let a drained battery keep your bike just collecting dust. Give us a call and it'll be going better than new!

BionX E-bike Battery Repair and Upgrade

Due to the nature of the BionX systems, we require the bike in order to validate the rebuild.

    Good day , having a tired Bionx 24v Nimh
    I2c battery and a good shape Bionx 36v Limn canbus battery . In order to use the 36v battery for my original 24v I2c bike can u
    install the original I2c 24v battery module in place of the 36v canbus battery module making her a compatible I2c battery for my bike ?
    Best regards

    @Michael – We cannot change the voltage of the battery because this would require changing the proprietary BionX BMS, which we don’t have.

    @Ken – Thanks Ken!

    Quick Bionx battery question. I believe you can run Bionx 36 volt motors with a 48 volt Bionx battery. I want to go the other way around. I have two old dead 36 volt Bionx batteries, and I want to match them with a 48 volt Bionx hub motor. Just use the 36 volt batteries as back-ups. If this works, I’ll have you rebuild the 36 volt batteries. Again, will a 48 volt Bionx hub motor work on rebuilt 36 volt batteries? Thanks.

    I have access to BionX battery keys
