An inverter will shut down at its own setting. But, I also have lights and other loads that that are directly connected to the batteries and do in fact pull all of my batteries down to BMS shutdown.

As a follow up to my original post: As requested my Min I am using and cycling the batteries to see if my one problem battery will eventually balance. It is getting much closer to a balanced pack so I am not pursuing replacement, although it is not as well balanced as the other two batterie...

While cycling my problem battery I used an inverter with a 15 amp load to discharge the battery and then charged it back up using a 12 volt power supply so I could closely control the voltage. SOK now says that the battery cannot be discharged with an inverter for their app to give correct...

I requested a replacement last evening. I will let you know how that goes.

The same cell dropped lower than the others at full discharge. I only have the capacity calculated by the SOK app and it is below specifications by only 4 AH. I didn’t time the discharge.

The problem I am having trouble getting my mind around is that cell 3 in this battery has always bumped charge protection mode causing my whole bank to have trouble. I will reach out to Min and see the response. Thanks for your input. Much appreciated.

It has been 35 hours since my last charge was completed. I had to reduce the charge voltage to 13.7 to prevent the BMS from entering charge protection mode. I have been floating the battery at 13.7 for 30 hours with no appreciable balancing taking place. The problem cell is still at a 0.319...

I am in the process of dischargeing the battery. It is at 19% SOC and all cells are within 0.003 volts. Discharge rate is 15 amps, so it takes a while. I will reach out when I get through the next charge cycle and float if it reaches the BMS balance threshold. Thanks

I have an SOK 206 AH battery with one cell that causes a BMS charge shutdown at approximately 13.7 volts. The other three cells have very little deviation in voltage but never reach max capacity since the single cell terminates the charge. The battery has been cycled a minimum of 5 times with...
