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.

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.
