    I reviewed the data and it looks good. What is your concern?

    Thomas, thanks you for good news!

    >What is your concern?

    1. I charge pack #4 (with CF=0) to full, but charge stop with FCC=~1900 (start FCC=2600, after calibrate ~2400). Why?

    I clear "Update Status" from 0x06 to 0x04, rewrite State,Qmax Pack (and Cell) to 2600 and reset bq40z50 from bqStudio.

    Nothing happened - FCC (address 0x16) no change from 1900. How to fix this problem?

    2. about State of Health - if I get fresh solder chip, make corrections only: Setting->Configuration, Setting->Manufacturing, Gas Gauging->Design->Capacity/Voltage. And after reset of chip I always see SoH=95% and FCC=~2500. Why? How to set 100% and 2600 for FCC?

    3. How to clear flag SMBLCAL? And I periodically can see SLPAD and SLPCC
