R Martin Ebike Battery

We can rebuild and upgrade all of the R Martin E-bike batteries whether they are rear rack mounted or slide in behind the seatpost tube. If your battery is losing power and not giving you as much range as it once was, let us take care of it and get it running better than new!

We can replace all of the cells inside with brand new, state of the art lithium ion 18650's. This can upgrade your capacity, increasing your range and ride time over the original specification. The battery above was originally 36V 14Ah in a 10S 7P configuration, but we are able to increase that all the way to 36V 21Ah!

We can also take care of their other rear rack mounted battery, upgrading it to at least 36V 14Ah.

All of our rebuilds are backed by our 1 year warranty. Don't let a dead battery keep you off your wheels, contact us today!

    @Tristan – It’s easier for us if you send us the case so we can rebuild the battery inside of it, guaranteeing it will fit back in your bike.
