Need the pinout for battery 74XCR Li-polymer
Good afternoon everyone. Long story short, I have a tablet Dell Venue 8 pro 5830 that works very well, but it is not charging its battery anymore.
It seems that the charging circuit is not working, so, while I am in parallel trying to find someone who can fix the circuit, I decided to try to build a kind of external charger for its battery.
This tablet uses a Li-polymer battery 74XCR (attached picture) and I need to find out what the pinout is for the 12 pin connector.
I am trying to build a simple charging system with a TP4056, but I am having trouble to identify what combination of wires from the 12 pin connector must be connected to the TP4056.
Does someone know the pinout for this 74XCR battery?
