Just in the process of wiring up my KLS-7275H controller with QSMotor hub motor for an electric motorbike conversion.
I’m using a contactor (Tyco Kilovac EV200AAANA) and had planned to control this with the 12v circuit from the bike (which I’m retaining along with a small 12v battery to drive lights/indicators etc) along with an additional kill switch.
Looking at the wiring diagram from Kelly in the controller documentation (see below) they show the contactor being controlled directly from the 72v circuit protected with a 2A fuse. Looks a bit dicey to me - has anyone done anything similar here?
