I updated the firmware whole the batteries were arou d 16-20% charged. It then read 100% after it updated.
I have two 200AH Lithium Ion batteries connected.
I am afraid of overcharging the batteries by manually choosing an estimated SOC, but I'm also afraid of over-discharging by NOT manually changing the SOC and them not charging above their current SOC because the system thinks they are at 100.
I guessed the SOC had charged to around 30%, so I manually changed it to that. Will a wrong guess damage my batteries as the system charges and then discharges???
What should I do???
