@djibattworkshop For example, what should the value be?, and how to solve this case?

 1st Level Safety tab 

 Change all instances of 4400mV to 4250mV (Cell OverVoltage setpoint) 

 Change all instances of 4200mV to 4050mV (Cell OverVoltage Recovery) 

 2nd Level Safety tab

 Change all instances of 4450mV to 4300mV (Safety OverVoltage setpoint) 

 Next steps are Chemistry profile and Sbs profile reprogramming. 

 p.s. 

Basically we not provide support for use of bqEVSW software because it is not NIP-Embedded product. But you could refer documentation and application notes from official developer on how to use this software. Also their support forum has a lot of useful information. 

every edit the value always returns to default, ex : 4.250 always back to 4400mv

SBS display now

max error 141
design voltage 11100
charging volts 0
charging current 0

 Unseal the chip and clear PF flags 

@djibattworkshop

The parameters seem to have changed a lot, but the max error is 141%, I've drained it to 3v and left it for 2 hours, and fully charged it, left it for 5 hours.

 It is wrong method. Check the tutorial carefully.
