New to lithium iron phosphate. Purchased a cheap China Vestoods battery. First battery worked fantastic fell in love, after a month or two bought two more.
Both new batteries show one cell overrunning voltage just before complete charge on other three cells. 3.855 versus 3.355.
Bluetooth BMS shows charge MOS disconnecting due to "serious cell Over voltage" error.
EBay vendor says this is normal but does not sound right to me? Any thoughts?
