You can set your motor current much higher than your battery current as the controller and the motors interact differently than the battery and the controller. You should set your “current” which is the amperage coming from your battery based on the specs and config of your pack. For e.g. I’m running a 12s4p pack of Molicel P42a’s and the battery current is set at 100 amps which the cells can handle without generating much heat.
Conversely, you can set your motor current based on what your controller and motors are rated for. For e.g. a Xenith running 6374s will do 80/-80 without difficulty as long as you heat sink the controller. Without a heatsink, you may consider lowering the current to reduce heat that is generated.
