I finally got my PlayBox. I installed a 10000mha li ion 3.7v 2 wire battery by soldering + & - to the bottom of 1 and 3 pins of the battery connector with the proper polarity and switched the jumper to the Batt position. Assembled it all together and tried to give it a full charge. I'm running the Pine Android LCD image. The battery shows it's charging in Android but the % doesn't increase. I then powered off leaving the 5v usb power supply that came with the board plugged in and the system switched over to charge mode. I left it sit for 16 hrs and when I powered up again Android shows exactly the same % of charge. What's going on???

The PMIC will NOT charge the batter using a two wire system.  The third wire (the center one, yellow on three wire systems) is required so that the charge system can monitor the temperature.  

You may 'fool' the PMIC by running a 10K ohm resistor from the center pin(2) to ground, on a two wire system, and then the PMIC will charge the battery.

(hope this helps you)
