FS75100 
Hi, I need to deal with a problem I have. I have a scooter FLJ sk3 2x3500W, battery 20S 72V and I bought the driver FS75100. I have 80A set for each motor.
The scooter rides quite well at the beginning, but after 1 km it loses power. the voltage on the battery is fine, which is causing a sharp do not know falling power! :(

If your temperature sensor wire is being used, it could be getting hot and cutting current. Try backing the current to 50A. Then test the resistance on each of the 3 power wires on each VESC from motor to VESC and be sure they have similar resistance.

Probably the fets temperaure soft cutoff is kicking in. If you have the bluetooth adapter, it can be monitored live.
