All of our battery leads are that long, so the battery would have to be launched up 6 inches to pull the connectors apart.
The best theory that I came up with is that it has something to do with the robot-side connector being bolted solidly to the frame (the "attacking side" that hits the defenses before anything else.)

The pictures really help people understand your situation.
The loops in your battery cables are long enough that the movement that is possible should not cause a good pair of connectors to come apart. How much force is needed to pull them apart? Try pulling at different angles. I don't see where your bumpers end up. Is it possible that another robot is hitting the battery wires? It seems that the constant in this is the connector on the robot side. Have you tried replacing it? Try putting painters tape so part of it is on the battery and part of it is on the bracket. Put other pieces so they are on one of the battery wires and the frame next to it. If anything is moving more than a few millimeters, the tape on it should tear and give you some clues.
