[BQ40z60] discharge termination without apparent fault and cell balancing

Hello all,

I try to do a learning cycle, but  the discharge is stopped automatically before the threshold I choose, do you have any clues?

All the flag not show are 0 except ITEN, on the last line.

An another little question...is the BQ40Z60 able to do cell balancing during charging?I have a relatively strong cell unbalance when the charging voltage is near the maximum and the charger stop with a COV error. For example, I need to program a 3,5V setting voltage (I use LIFePo4) whereas the cut-off is 3,65V if I want a normal charge termination.

I also have a similar phenomenon on discharge with CUV, but it is less important to me.

Best regards,

Wilfrid
