Check your Anderson battery connectors

The inside of the bumper comes right up against the outside face of the aluminum on the other side of the connector. Sorry if I'm not explaining it properly, we don't really have good pictures.

And both times the connector did dislodge, it happened during the second (this really baffles us) crossing of the rock wall. So no robot was hitting the connector at the time.

Have you tried installing the battery and putting the Velcro strap on then try lifting the robot by lifting the battery? Perhaps the battery is "jumping up" and stretching the Velcro strap then popping back into position during the violent manoeuvre.

At Bayou yesterday, we popped our PDP panel off and separated all the Anderson connectors to our motor controllers when we hit the Portcullis too hard. It was stuck on with two long strips of Duo Lock which holds more strongly than Velcro. We (and others) have broken things that have never broken before.
