Just noticed this. Have 5 SOK SK48v100 server rack batteries. 3 mo old. Just noted one of the batteries wasn’t getting to the same level of charge as the other 4. The BMS data shows nothing out of the ordinary. Please see screenshots. Ideas?

Someone will be along with an answer.
Where did you buy them? And are they installed or their instructions esp regarding wire length.

It's normal for parallel batteries to drift apart in the middle of the charge curve. They will re balance at full charge.
Did more reading last night- I don't think my battery packs have reached 100% charge for last 2 weeks with the heat wave using up all my PV production. Doing a grid charge right now- lets see what happens.
