Are the 2 VESC’s connected via can bus or split ppm? I could logically see an issue with can since they are 2 different VESC’s which handle BAT MIN differently…maybe, hell I don’t know. Either way, I would rule it out by switching to split PPM and see if the problem goes away.
Pretty sure they’re both using same firmware version and all the firmware settings are the same. No idea what the temps were but they should be perfectly fine as I’ve done this path 100s of times with no issues and its largely downhill at the point where I started getting issues so nothing should be getting pushed particularly hard.
I’m leaning towards it being a short somewhere in the motor so I’ll be opening them up tonight to check but happy to hear other ideas still
