Connect Battery Backup

Optionally, you can connect a rechargeable Li-Ion/Li-Polymer battery to the mangOH
green to provide uninterrupted power in the event that the primary power supply (DC
or USB) fails.
If a jumper is placed on CN1201, the mangOH green recharges the battery and then
provides a trickle charge to maintain the battery's full charge.
To connect a rechargeable Li-Ion/Li-Polymer battery to the mangOH green:
1. Connect the battery to CN1202.

2. If you want the battery to recharge while connected to the board, place a jumper
across the pins on CN1203 (Recharge select).
Caution: If a rechargeable battery is not connected to the board, make sure to remove the
jumper from CN1203.
