BQ40Z60 Evaluation Board Max error - state of charge 100%

Hi,

I am testing a BQ40Z60 evaluation board with 2s cells. I changed the jumper J4 to 2S and set DA Config (CC1 and CC0) and set the cell cemistry correct.

I also did temperature and Voltage calibration. It is also possible to charge and discharge the cells (just tested with power supply and some LEDs)

My problem is, that the Max error = 100%, Relative state of charge = 100%, Absolute State of charge = 0% all the time.

Do I have to perform a learning cycle? If yes, how can I do it.

Best regards
