I had a great EM3EV 149SP battery. I wanted to try something with more power.
I can fit a wider battery, but not longer/taller battery into my bike frame. Being stuck at 52v/42 amps was something I wanted to upgrade from.

Needless to say, after cleaning a lot of burn residue off the frame, I am back to the EM3EV battery. It's interesting that it is advertised as having a BMS - it doesn't even have an on/off switch.

Just thought I'd share for anyone who was having a bad maintenance day - it could be worse! :lol:
