This is exactly the case for my battery. Small charges and discharges and charging laptops, phones etc via the inverter. I think the SOC-calculations is wide off.
I did charge the battery full and left it a few days to settle. Last weekend there was no problems.
I'm gonna monitor the voltages...
Hi and thank you for an excellent forum!
I have a 200 Ah LiFEPO4 battery with a built in jdb BMS (JBD-SP04S034-L4S-200A). The battery powers from a 170W solar cell through a Victron BlueSolar MPPT 75/15.
The loads on the battery are usually low 2-5A. Occasionally 10-15A when using 230V AC...
Thanks for your answers! Yes the battery probably defect. When it went dead this time soc reported still around 50% and capacity left 100aH.
The first two times it went dead soc reported around 80-90%.
It's now fully charged but one cell is 0.1V lower than the others that is completely balanced...
