Part Number: BQ40Z50-R1

Dears,

1.My battery spec is 3s1p 2200mA.  I want to do golden image . Now procedure is in learning cycle stage. Should I need to  let  update status change to  0x06 or 0x0e in learning cycle?

2.For golden image I need set update status to 0x02 or 0x0a?

3. If I finish learn cycle and export gg file. The Cycle Count and  Qmax Cycle Count need clear to 0x00. Is it right?  

Thanks!!

    -Since you have 3s, update status could be 06 or 0e at the end of learning indicating qmax and resistance update has occured if 06, and cell balancing is active if 0e.
    -Golden image should have 02. cell balancing will only be active after the gauge has learnt the actual capacity of that particular cell at which point update status would be 0e.
    - yes clear to 0
