We had an entirely different problem. Two matches in a row, our battery connector actually separated from the connector on the robot. Both times, it happened after going over the rock wall the second time.
The part that bugs me the most is that we had hours and hours of practice, and this never happened. Also, the connectors on those batteries and the one on the robot were properly constructed, and they are just as hard to pull (wiggle) apart as those on any of our other robots.

The first match, when we pulled the robot off the field, we wiggled the connector and the robot turned back on.
The second match, everyone on the drive team checked to make sure the connectors were properly seated. When we pulled the dead bot off the field, the battery connectors were at least 3/8" away from being fully seated.

Being dead for two of nine matches really sucks. Fixed by zip tying the connectors together.
