Hi guys need your help I've get a new controller 2000w 72v max 45amp thinking it was my new 72v I swap it for my old 52v battery but only getting about 8mph on full throttle. I've got 2 sw900 display both doing the same.
As the controller is dual-mode I've tried it with the sensors off and on still the same could the controller be faulty
