The rules this year give teams the option of designing a series diode into the input of an onboard backup battery charger circuit. That solves the problem of the backup battery attempting to power the entire robot.

So far as I know, we aren't using the backup battery for anything besides the control system backup power. Still, we'll be using an onboard charger just for the convenience of not having to remove, recharge, and replace it.
