Hi
We are using 4S1P 25Ah lithium iron phosphate (LifePO4) battery.
We are experiencing an odd behavior while charging the battery to full while using CC-CV charger with taper current of 1A.
After battery fully charged (RSOC = 100%) and relaxed for 5 hours, the remaining capacity gets updated and RSOC drops to about 70% after "Relax smooth time" that is 1000 seconds.
This happens while nothing loads the battery.
Is it suppose to work like that? If yes, can we disable it?
