    Sabvoton 72150 help

    Amberwolf. I've set the controller to 100amps, not as quick, but top speed is roughly the same. Tbh it's not used much right now as it's freezing here in Scotland. I think the next move is to build my own pack with a Bluetooth BMS.

    Sabvoton 72150 help

    Hi. I have recently finished my build. Specs are QS 205 50h 5T, sabvoton 72150 and 72v 40ah battery with Samsung 35E cells, 3500s. I only have the Bluetooth app set up and the bike runs ok though top speed is just under 40mph and torque won't lift the front unless I help it. I am wondering what...
