Hi, Havent heard from anyone but can give an update.
Note: Im not the only one with this problem as i have been approached by a few others.
I have bought a cheap replacement battery pack and can see the 4th wire (green) is used for a NTC thermister to monitor battery temp. Does anyone know where this is connected on the main board (PCB/PWB), remebering i pulled the SMD connector off the board and cant obviously see where this pin is connected.
The other 3 are for charging and monitoring the 2 cells.
If anyone can find the track that the green wire, 4th of the smd battery connector, is conencted i will do the repair and load photos to help others.
Sometimes the thermister is not used but as charging to just over 8v (max allowed 4.2v charging) it is pushing the battery so it is likely used.
