Prodigy 50 points
Part Number: BQ40Z80


Hello.
I'm having trouble learning capacity of 6S9P INR18650-30Q 
I am unable to change the LStatus flag from 0x04 to 0x05

I have log of charging and discharging.

I don't know where the problem is that it won't get to the next stage.

    Hi,

    I don't see relax before charge section in the log file, you need to discharge the battery to empty then relax for 5 hours, then charge to full and relax for 2 hours, then discharge at C/10~ C/5 rate to empty and relax for 5 hours. You can refer to app note SLUA848 for a better understanding. 

    Best Regards,

    Abraham
