BionX E-Bike Battery Replacement

Posted on September 12 2023

BionX rear rack 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.

    @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 a 36 volt 3500HT rear rack BionX on my recumbent trike. The battery will no longer accept a charge. I am in Alabama so could I ship the battery to you for a rebuild? What would be the cost?

    @Liz – We can rebuild your existing battery as long as the other electronics are still good.

  • EBike Marketplace: July 22, 2019

    @Dianne – We’d be happy to try to rebuild your battery, but we do not have keys for the lock.

    The battery pack on my BionX bike needs rebuilding. I saw this set of instructions and wondered if you could do the rebuild as described: https://www.instructables.com/id/How-to-Rebuild-a-BionX-E-Bike-Battery-Pack/

    @Phil – We only rebuild existing batteries for BionX systems. We do not sell new batteries.

    I have a 36V Bionx on my Catrike Trike. I have had it about 5 years and it will no longer hold a charge. Since I have some leg disability I depend on it to help negotiate larger hills. Is it cheaper to have it rebuilt on purchase new. What is the cost of each?

  • EBike Marketplace: June 26, 2019

    @Deb – Yes, we can rebuild the battery as long as the other electronics are still good.

  • EBike Marketplace: June 26, 2019

    @Gayle – Sorry, we can’t help with the keys. But maybe get a local locksmith to drill out the lock?

  • Deb: June 26, 2019

    Looking to have my Bionx 48V refurbished – bought it 5 years ago and used it about 10 times. Did not charge it last 2 years – now it will not hold the charge.
    Are you able to fix this ?

  • Gayle Paquette: June 26, 2019

    Hi,

  • EBike Marketplace: June 24, 2019

    @Wendell – Send us a picture of the part that’s giving you issues and we’ll see what we can do.

    I have a Bronx SL 350 HT RR XL 48V 8.8Ah 423 Wh battery that has good cells but that will no longer charge. Some problem with the female connector for the power source. Do you have any options for me?
