Becareful with this rule and circuit diagram from FIRST. I think the rules say "charging circuit". That means, the 7.2 battery should STILL be on the robot is the way I interpret the rules, not missing and powered soloely by the 12V battery.
I know your probablly only testing it on the bench now and only need the 7.2 power directly from your 12V, but I figured I would point that out incase anyone got any bright ideas.
<R53> The 7.2v backup battery may be charged on or off the robot. When off the robot, the battery is to be
charged with the provided 7.2V backup battery charger. When mounted on the robot, the backup battery may
be charged from the EX18-12 primary battery by using the custom charging circuit available from Innovation
First Inc. (note: IFI will provide the design for this circuit on the IFI website, however teams must obtain the
parts for this circuit and assemble it themselves)
