Lithium 3.7 Volt Battery

[tllim]

I bought 4 x 3.7 v LiPO 2000Mh batteries - assuming they'd work on Pine64 (I bought them for CHIP originally - but hoped they'd be interchange-able)...  But connector is wrong.

It would be >NICE< if Pine could provide some part numbers for people OUTSIDE the USA to buy compatible batteries...

And I can't find any diagrams of which pins do what on the LiPO connector...  I'm assuming that the middle pin does nothing - or is GND ?

In general, any 3.7v Lipo battery will work. The first pin is positive, the third pin is ground, the info posted at Pine64 wiki page on the main board connector information. The middle pin is temp sensor for those battery that has temp sensor.

It would be really helpful to be told of a UK equivalent. i've been looking on fleabay, amazon etc but they all seem to be very low mAh. The chinese ones on ebay seem ok but delivery wait and import times are long, and they dont actually have the connector either. Any help would be good?

Due to Lithium battery can blow up and cause fire, I cannot simply recommend.

TLim - I can't find any doco about which pins to what on the board at the wiki...  There's a VERY badly over-exposed photo pointing 

to the connector - and this information as text on the page :

Power Usage

• Input Power: DC 5V @ 2A, 3.7V Li-Ion battery connector, microUSB connector, Euler connector
  
  
• Power Consumption: 2.5W
  

This image just mentions "3 pins" :


(also - "Wifi+BT" is an add-on - and BT doesn't work in Android 5.1.1 - and I can't get it to work in Debian Jessie either)

This document is not very helpful :

I don't want to read a board schematic - I'm not an electrical engineer - I just want to make sure, hopefully with the help of a NICE pretty picture, I'm connecting the right pins when I hook up a battery to it...

I just check Pine64 wiki page and looks like we miss out this info. I will put in this info together with our Lithium Battery spec on this week.
