The FMS doesn't directly communicates with the robot.

The FMS will tell your DS computer when to be disabled, auto, and tele modes, but it is your DS computer that sends all packets to the robot via the wifi radio on the field. The Practice match sends the same info. The code on the cRIO runs the same whether on field or in pits.

If your battery is able to fall out once, it is likely that it was loose at other times. When not held firmly in place, the battery is a 12 lb. sledge hammer banging into your other components. It easily knocks wires out of Wago terminals, knocks ribbon cables off, knocks wires and terminals against the frame, etc. As Alan said, its direction of travel will also depend quite a lot on the type of hit.
