Hey all,
Per the title, I'm seeing a battery stop charging at 78%, just barely into the 4th light. The SOC on the EG4 3000 Inverter is showing 78%, but right around that time the voltage is sky-rocketing like it's full. Could it be a bad cell? But then the voltage should be even lower, right?
Some other thread was saying to keep it at 100% for 4+ hours and that it would see that the SOC is 100% and the BMS would reset the value but I let it do that over night and it still said 78% by the end of the night, same voltage of something like 56.4V which is the bulk charging voltage for Li4 setting in the Inverter.
Another thread was saying to change it from 56.4V charge to 57.2V and it would get to 100%, thoughts on that? I'll try it next time I disconnect the other 2 batteries in the group.
Another factoid, this battery is the V1 and the other two batteries that act normal are the V2 (for my above testing, I had these two batteries completely off to help rule them out). Also I'm using EG4 3000 V2. So this is the only component that's V1. SigSolar will probably be happy because my current thought is to buy a new battery and just use this potentially dud battery in the famous Will Prowse hand-cart inverter/battery setup.
Thanks!
