@glyphiks you made me go physically dig into an enclosure LOL
So my dual VESC 6 Mk3 is connected like this
The BATT+ of both ESCs are connected together and the BATT- of both ESCs are connected together. It has a loopkey. None of the switch shit is even connected to anything. It works fine.
Wire it like a FOCBOX 1.6 if you want to
