Thanks for your reaction. I am gonna check the cells. But what about the voltage drop in my question?

I recently bought 8 pieces of CALB 100AH cells to make and 200ah 12V battery bank. So far so good. I did a balance at 2.9v before charging. When charging it, with a Victron Multiplus, with 14.4V the first cell peaked at 3.7v when the others where at 3.43 ish (photo) So I switched some cells...

Okay, the seller of my grade A CALB cells told me that a difference of 0,2V is normal. I got a better difference, 13mv while charging.

That's true. What is, in your opinion, a good balanced set of cells? How many MV difference is your reference?

But that also doesn't have a (capable) balance function right?

I don't know if the rest balance. I just started using my Daly BMS this week so I have the figure out a bit more. But yes, the discription of those sellers is not really good. The Xiaoziang should, on paper, be the one for me but it isn't really reliable.. The Daly looks very well build but for...

I have the same, only the Daly 120a BMS version. They made all the wires exactly as I ask which was great. But when I tried it on a "unbalanced" battery (60mv apart of eachother) it did not balance. I asked the seller from of which MV difference they will balance but they don't say. They also...

I really don't know the problem. The seller is saying there is an iPhone app coming july 20 but they can't help me further or with anything else. Don't really want to buy another one. I ordered a Daly BMS insteadbut they, according to Daly Shop, don't have any balance function while it says it...

Nope, still no solution. I try to charge the battery, it gives the right voltages at the output but I can't monitor. Did you tried it on a Android phone as well?

I will do. I will put a post up this weekend about it. Thanks for the info! It is balancing the lifepo4 Calb cells around 1 to 2 mv from eachother. With a off balance start from 27mv, it took about three days to balance it to 2mv difference. I think that's very (very) slow?! Does the seperate...

I see in the screenshot that it supports lifepo4 (life) batteries. I will check it out when I get charging and discharging via the Daly the couple of weeks. But what's the difference between seperate port charging en common port? Great, I will try it out.

Where did you found that? What I read about the BattGO BG-8S is that it is working with Lifepo4. In fact it is balancing the cells right now. It takes a huge amount of time but still. The Active Balancer you pointed out does need an external supply which I don't have in the RV. Talked to the...

I have 8 new CalB 100ah cells which I made a 12V battery pack from. So a 200ah 12V (4x2S) battery which I use it in my RV. I have a solar charger with 100watt solarpanel and a Victron Multiplus for charging and inverting. I use very little AH, maximum 14ah with the fridge and heating on. The...

0,35ma? That is really bad indeed. I think I will do that then. Use a Daly BMS for protection and the BG-8S for monitoring if it need balancing. Can't find a reliable BMS which have it all. A Daly with better balance function and bluetooth would be the way to go. The Daly is really good build...

Great, thanks for you explanation! I think I'm gonna use a Daly BMS then, a 4S 12volt BMS for my 8S (4x2S) 12v battery and will monitor it with a BattGO BG-8S to watch all individual cells. Just to be sure then. I think that would be a good enough system :) I know you can use a separate port...
