Hi Dunc,
I have never seen or heard of a fuse in the motor circuit. The fuse needs to be in the battery circuit.

Hi Dunc,I was expecting to be using a 500 or 600 amp fuse in the motor circuit to go with an OpenRevolt 500 amp controller
I wouldn't put a fuse in the motor circuit - if it were to open up from high current then the motor's inductance will create a huge overvoltage spike (by jumping across the fuse terminals) to maintain current flow. Really a bad idea. It's why I don't like to see contactors in the motor circuit, either.From this a 200 amp J Type would probably be OK for my motor - it would need 100 seconds on 500 amps to blow
The battery (100Ah TS) could be protected by a 200 amp fast blow Tjs Type as it would take 100 seconds at 3C to blow
Am I reading this correctly?
