Are you saying once I get down to .006 difference, bump up the charging voltage 1/10?Sure
I'd stop when it gets to .06v diff
3.5v will probably show a bigger difference.

Stop increasing voltage when the cell diff gets to around .06vAre you saying once I get down to .006 difference, bump up the charging voltage 1/10?
Yes voltage will converge in middle charge range. Increase voltage to 13.60 and let it balance.seems like it might already be working. I put the charging voltage down to 13.4 on absorption and float.View attachment 293944
Here's how it is right now and the voltage difference just keeps climbing. Sell one is out of control.View attachment 293908
Is it okay to use the battery while I do this? I'm just curious. I don't really need it cuz it's just in my camper. I was just wondering for the learning aspect.Yes cell 1 is fully charged and the others are maybe 94% to 97%. Going to take some real time.
Keep settings the same and post again tomorrow.
I got this today. Looks like it's doing much better. This is setting the charger to 13.5 Volts for both absorption and float. Time to bump it up a tenth of a volt?View attachment 294400
Thanks a lot man. I really appreciate your help!Looking good. Yes bump it up. 13.70 should hold fine today. Tomorrow still looks good it can go to 14.00
Are you saying to bump that up from 3.35 to 3.41? If so, do you mean right now or later?Your start balance V is low, but sometimes starting it low is exactly what you want when a cell proves to be the high SOC, imbalanced one. In your situation, it definitely helped.
Under normal conditions, 3.410V with a .015V differential is a good setting to catch early drifters as long as the connections are good.
That is dead nuts on perfect.It was doing so good at 13.7 I went ahead and raised it to 14 about an hour ago and here is what I have. Tell me what you think.
Change it now ,.Are you saying to bump that up from 3.35 to 3.41? If so, do you mean right now or later?
Looks good, go to 14.2v tomorrow ( or today if you have time)It was doing so good at 13.7 I went ahead and raised it to 14 about an hour ago and here is what I have. Tell me what you think.
99% of the time 3.35V vs >3.40V will mean little since you also have to realize a .015V differential before balancing will actually start and you'll never see that unless cells are truly imbalanced.Are you saying to bump that up from 3.35 to 3.41? If so, do you mean right now or later?
I've testes a bunch of JBDs over the years and their V accuracy is very good. So based on that, I would say your battery is more than good enough to put in use already. their shunt is not quite as good though, so if you have a way to verify current, do for peace of mind.Here it is at 14.2 Volts for about an hour or a little more. Looks really good. Am I done? Go ahead and cycle the battery?View attachment 294444
Use it as normal, looks like a healthy battery.time2roll? I see you gave me a thumbs up about my last question. It's 5:00 right now and probably only 3 hours of shitty Sun left. You think I should cycle something small in my camper all night long or what should I do? I can leave the TV on it takes about 60 watts. Or you tell me how many watts you think I should leave on it. I usually turn something on like my max air vent fan which takes about 30 Watts all night long to cycle the battery. Tell me what you think please.
