Hello dears,
I am importing Felicity LPBA 48V 170 Ah 16s1p LiFePo4 battery which defined to be CATL grade A cells from China. unfortunately 1 battery I installed it for my sister's house after it gets fully charged from utility for example and restrd long time on around 54v but stops charging by BMS and shows 100% SoC, when utility or sun disappears so inverter starts taking power from the battery and even it take just few ampers from it, after few minutes its voltage drops to around 52.5v or less and SoC is showing 98% for example. does this voltage suits that SoC? and the voltage drops fastly to 52.5V which is logically indicates <75% but BMS SoC is showing above 95%?
yesterday when the battery has got fully charged from the utility and stopped charging I connected the BMS to the PC monitor I surprised that difference between cells reached 0.2v as the attached photo shows. is it logic for a new battery?
please tell me your feedback.
