 Go to Discharge Tab, start discharge, wait 30s and paste a picture. 

 During discharge, touch mosfets on the pcb with a fingertips to check if they are heated.

Select "Ignore SoC" option to allow discharge.

Read a battery by bqEVSW tool to check all registers.

 There is no Safety page on this version. 

Try the following

- disconnect ev2300 smbus connector from a battery 

- start bqEVSW, select bq30z55_v0.36 manually 

- reconnect ev2300 smbus connector 

- read main page and Safety page 

- paste two snapshots
