Thank you for the feedback, I have forwarded your comments to the build team. We switched out all motor controllers and individually tested them one per side to see if any of them were tripping breakers, with no avail.
Here are three pictures of the CIMple box coupling itself:

Something to note is that the build team tells me that there is a two stage reduction gear ratio inside the CIMple box itself. We don't have a multi meter at the moment to get readings, we will take readings once at the competition.
We're still encountering issues with voltage drop even with all Safejaguar classes replaced with normal motor controller classes.
