unseal not working for reset/reprogramming.
pls approve for remote reset
Approved.
successfully reset by admin, thanks.
received the battery today. noted issue with cells voltages.
on multimeter voltages are 4050mv, 4050mv, 4060mv.
is it calibration parameters issue?
how to resolve?
checked cells resistance externally which is 73, 81, 75mOhm
received the battery today. noted issue with cells voltages
Check cells voltage on Test Battery Demo software
is it calibration parameters issue?
It could be hardware issue too, pcb or chip fault
how to resolve?
Depending on the root cause which is unknown at the moment
Root cause - Solution
Calibration issue - Calibrate ADC channels
PCB issue - replace faulty components
Chip issue - replace chip
Check cells voltage on Test Battery Demo software
same as NLBA
Calibration issue - Calibrate ADC channels
how to calibrate ADC channels? through BQ software( and how)?
through BQ software( and how)?
yes
how to calibrate ADC channels?
follow TI guidelines
root cause should be clarified first otherwise you could waste a time on the non relevant matters
For example there is no sense to calibrate a chip if pcb is faulty

pls suggest what should be checked to trace out.
Measure cells voltages directly on the chip pins.
