Hello to both of you,
I finally went back home.
I charged my battery, then I disassembled it to top balanced it again. Once it was top balanced to 3,65 V, I directly assembled it into a 12V
pack (I didn't put it back in my RV yet).
Should I left it several hours in parallel before assembling it in series ?
Here is what I get on the BMS app. Is the voltage differential of 0,023 V anormal ? You can notice that I don't get "Protection none" anymore but protection cell overvoltage.
Also, I measured 14,65V between the main battery positive and "B-" of the BMS.
But I get 14,35 V between the main positive and the "B+" of the BMS.
Is this normal ?
I am so confused with all of it and I really don't know what to do.

Edit :
Look what happened now to cell number 2. I am wondering if this cell died and if I should replace it...
