Posted on July 10 2018
Do you have an A2B Kuo, Kuo+, Fast4ward or other model that uses this e-bike smart battery? We can service and rebuild it for you if it's not giving you the range it originally did. These batteries pack in 28 cells in a 7S 4P configuration allowing us to upgrade it up to 24V 12Ah, giving you 30% more range than the original!

hello how much cost of fast4ward edge ebike batteries
@Jules – Yes, our rebuild service should fix this. We’ll be in touch with our recommendations!
I just bought this bike used and the battery seems to be working fine. However, the owner had it in storage for about 3-4 years. It’s giving me about 25 miles per charge, but the manual says if there is going to be long term storage and the BMS is turned on it can permanently damage the battery. Should I be concerned? What is this permanent damage? Is it something this service/rebuild could fix?
@Robert – We prefer to re-use the existing BMS if we can.
Hi, I have a fast4ward folding bike with a failed battery. When you rebuild do you use the existing BMS or replace with modern. If you replace, do you retain all the bike functions? I was thinking about the 2 supplementary connections from the BMS to the bike via the 4 connections on the battery holder.(don’t know their function)
@Larus – We only rebuild batteries that are sent in to us. We do not stock new ones.
@William – We’d be happy to rebuild and upgrade your battery for you:

A couple of years ago I purchased a a2b kuo 24v/12a e-bike. I’m looking into replacing the battery, I was wondering whether the 36v battery will work with my current bike? if yes, do you have one? how much it will cost? and can you ship it to Israel?
@Larus – We can rebuild your existing batteries if you send them in to us, but we do not stock this battery.
