My desired value is a max of 400 amps. If I set bat-amps-lim to 0400, the controller stops working. I think it is limiting battery amps to zero or a very low value.
Does anyone know if "bat-amps.lim" works? Am I not setting or using it correctly?
Thanks

I have not tested it ... at least I don't think so .. but I think that there is an implied decimal. So 400 = 40.0 amps.
I have tried the motor amps limit, and it does work. The motor current can't be larger than the battery current .. so if the battery current is not working you can work around it with the motor current.
The only bad part about this is that your acceleration will be worse, since the battery current can be 400 amps at your pack voltage, while the motor current is 1600 amps at 1/4 of your pack voltage.
Let us know what you figure out!
