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.
CIMple Boxes are single stage, 4.67:1 ratio. They almost have to have a second reduction stage after them, and those photos don't look like you have one. So I think you're definitely geared too high. The best solution is to change things to get a lower gear ratio. That'd be putting a smaller pulley/sprocket on shaft out of your CIMple Box. I expect you don't have belts or pulleys to do that with, but another team near you might. Switching to chain would also work, and it's easier to make chain shorter than to buy new belts in the exact correct length.
