What if I swapped it to a different position? Never mind, that was a stupid thought on my part.

I think you are correct. Something is wrong with cell 9 and I could be repairing forever unless I deal with that problem.

I may have to consider fuses if I cannot figure out why the balance resistors are getting fried.

That's what I thought. It is burning up the balance resistors even if I lower the balance current. Cell 9 is always involved. The other cells are close by. I have been through 3 JK BMS units and they all have the same issue so perhaps the arrangement is a problem or cell 9 itself is...

I have another thought. The 16 cells are connected in two groups of 8 each. Within each bank of 8, they are connected by bus bars, but the two banks are connected by a cable. Would that make a difference because cell 9 is the first one in the second bank and cell 8 has also gone bad twice...

I set it to 3.45V. I had it there originally, but things were failing so I tried a lower balance. It didn't help, so we are back to 3.45V. We'll see. I may have to improve my soldering skills. I have many multimeters. Power supply went bad, but at the moment I am charging the battery...

Thanks so much to upnorthandpersonal for his help. I could hardly express how thankful I am to him. But as many have pointed out, there must be something causing the problems in my 16S configuration with this JK BMS. Cell number 9 was always involved. And believe it or not, a week or so...

How are things going?

How are things going? My third BMS is still working with the reduced balancing current.

Thank you so much. I mentioned that we manually transfer between the grid and solar a few times a week. I have made a few modifications to the transfer process and have reduced the balancing current. Looks good so far! I also noticed when I was running the full 2A balance that there were...

Thank you!

Sounds good, I'll work on that when I get the stuff to build a new harness, or buy one. Soon!

No.

Just FYI since I am on my third and last JK BMS, I did reduce the balancing current from 2A to 1.5A. So far it is working, but who knows why? I have a manual transfer switch from the grid to pure solar power. I have been careful to make sure that the inverter is up and running before making...

Are you saying that the Victron Chargers don't actually hold the voltage settings?
