Hello Larry -

If the team is going to use the main battery to charge the backup battery then you can only use the schematics provided by IFI to design and build the circuit.

Thank you for your question.
FRC OPS SUPPORT
So, you run two backup batteries and swap them every match, keeping the spare on the charger between matches. Prior to the competition you load test the batteries to make sure that neither is laying down on you. You should also consider changing out the connector on the battery to the powerpole unit used on model airplanes. The connector that comes on the battery can develop intermitent contacts and this can lead to spurious RC controller resets.
