Hi @AHMC, After our testing, a SOC difference of around 10% is a normal phenomenon. Different batteries will discharge in turn to gradually reduce the SOC difference.
Hello @BLUETTI_CARE
Thank you for letting me know that a SOC difference of around 10% is okay!
I do have another observation that I am concerned about. When I am watching the screen that shows the individual CELL voltages (for either the AC200Max battery or the B230 expansion battery), I’ve noticed voltage differences by as much as 0.210 volts. See example picture below. A 0.210 volt difference seems excessive and, if I’m not mistaken, indicates cells that are very out of balance. Can you comment on this observation?
Hi AHMC, you’re welcome.
We consider this voltage difference to also be within the acceptable range.
Could you please test the voltage difference of the battery when it is fully charged and when it is at 0% power respectively? This will help us further analyze the battery status.
