bq27541-v200 fuel gauge learning cycle issue

Dear  TI!

I have a high power application based on MOLI-IBR18650B cells.

There are 16 paralell connected cells in the battery. I divided the current and capacity range in calibration because I have higher loads than +-32A.

I use the battery pack between 3-4V. I cannot achieve succesful learning cycle. I measured the passed capacity between 3-4V and set like a Qmax value.

I set the terminate voltage to 3V. When I discharge the battery empty to begin the calibration the full charge capacity register has different value then Qmax.

I do not use reserve capacity value.

When I finish the charging at 4V (and FC bit is set; and charger is disconnected) and the more than 2 hours relax time the "Update status" never changes from 04.

So all of the learning cycles were failed.

What do I wrong? Do you have any advice for this problem?

Thank you!
