I hope that the drive train is not detailed in your drawing. There is a need for slip clutches in the differentials to allow turning. Without them the drive motors go into stall during turns. Just two drills or two Chalupas driving the wheels means 200+ amps during turns. Add the two FP, two Chalups and two drills and you have exceeded the current capabilities of the battery and possibly tripped the 120 amp breaker. There was a GM team who had a similar design without the clutches and they repeatedly set the drill motors on fire during turns using one drill for front and one drill for back. This is one application where current sensing is an eye opener. Sorry.
