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)
ThankX Mark, I'll try that. At least I now know.

Mark, Should I use a thermistor or is it safe to just use a resistor?
A thermistor doesn't buy you anything because its not mounted in the battery package. You may use a standard half watt 10K ohm resistor.

You could add a thermistor, and attach it to the side of the battery pack, but we'd then need to know what value thermistor Pine64 are using in their battery pack, as there are several different resistance ranges to pick from. And you could still need to add the resistor anyway, as they are usually used in a voltage-divider style circuit. There isn't enough information about that part of the circuity atm. Just use a 10k resistor across the GND and middle pin, and your pine64 will be happy to charge and use the battery.

1/4 or even 1/8 is fine, as it is simply clamping the temperature sense pin to GND.

Yes, it probably is going to be just fine. If you want to make sure (I have not measured it) you can measure the current by taking a voltage drop reading across the resistor-- do the math, if voltage times current is 0.250 or less a 1/4 watt resistor will work fine. Its really a pull-down resistor to ground and not much current passes through it I suspect.

Got it Mark, ThankX.
Having read the entire post, I know all about which battery to use and how to fake it into thinking the battery is OK so it charges. I actually ordered a couple 8000 mha batteries which are two lead and expect them any day now. I looked for a battery with temperature sensing but was unable to find any.
Does anyone have a link to a battery that actually has temperature sensing? The originators of the Pine64 got them from somewhere. Anyone have a link to a battery that has all three leads and the correct connector?
Thanks in advance.

Finally manage to bet one batch of 8000mAH battery import into US, we will post on store soon. However, only limit to UIS due to flight regulation. I will post the battery spec on wiki page tomorrow.
