So I wanted to be able to recycle ebike batteries, I found that Gouach batteries founded by Alexandre Vallet designed a repairable ebike battery, it has very next level features, the cells press in without spot welding so they can be replaced. The BMS is replacable, you can connect by bluetooth to monitor the individual cell groups to see if their is an over or undervoltage error that is the main failure mode of ebike batteries, the batteries turns itself on by tapping, and when the cells are old you can replace them and keep going with the same battery. I am in victoria b.c., if you have an ebike battery that has failed I can help you rescue the cells that are good and get you started with and infinite battery.
