 You need to find out which pin is System Present pin. 

 - Disconnect all the wires 

 - Connect only Gnd, Clock and Data to battery connector 

 - take picture of wiring 

 - read battery with bqEVSW 

Paste bqEVSW SBS page snapshot and picture of 3 wires connected. 

 

p.s. 

It should be done on second battery from other topic !

I don't have access to that one.

I had to return it to the owner.
