I was sceptical at first, since the overkill bms I use for my 200AH battery pack has balancing as well. It would regularly not charge further than 130AH. Also, during charge and discharge the battery pack voltage difference would regularly get up to 300 mV, meaning that the weakest cell would interrupt discharge and charge. Attached this unit, discharged the battery pack and noticed that I could discharge it much further than before, because the voltage differences between the cells are now 50mV max. Then charged the battery pack, and indeed it got up to 195AH, since the difference during charging is also less than 50mV. I turned off the balancing on the overkill bms during this test btw. I don't think I will turn it on either again

Purchased for 7s Lifepo4 custom pack (was going to be 8s until I literally made one of the batteries explode by accident (not with the balancer, i just drilled too far) then replaced it with one that did not play well with the original 7 and also exploded....again I did not have the balancer attached and it might have saved me there) but anyway, after $500 in burned/exploded batteries I bought a balancer, this balancer works ok if you have a few days to let it sit then it will bring all the cells to within 0.0 at best. This of course being a gigantic waste of energy storage if one cell is at 3.011 and others at 3.099. So instead of purchasing a 200 or 500 dollar unit (that might not be any better anyway) I've installed the cells to a rolling rack and I keep a multimeter nearby. Once every couple weeks I will wheel out the battery cells and adjust all 7 manually so if one is low I will use a charger to bring it up to the others, if one is higher than the others I will clamp on a 12v RV ceiling light, that was just sitting leftover after I replaced all of them, to slowly drop some energy until all 7 cells read 3.700v. Also I may have OCD, lol. This balancer will keep you in the safe zone so you can set it and forget it for most uses. If you want the ultimate balance, nothing beats a multimeter, a light bulb, and about 24 hours of free time, lol. I'm also glad it will work with 6 to 8 cells, since 1 of mine blew up for unrelated reasons. Also, mount your custom batteries where you can glance at all of them very easily. They puff up before they cause a large explosion and a ton of fire. Standard ABC extinguishers will put it out (ask me how I know) but the fumes probably gave me cancer...

I’ve read for years that these are junk and watches Will Prowse on YouTube destroy these several times. So right off the bat I thermal pasted the caps to a big block of aluminum and wired it up. Two days later the 12,000 ah 24v pack was PERFECTLY balanced and here two months later it’s still is. Love it! Also I hooked it up to a scooter battery and charged ONLY one section at 3amps and by the end of the day they were all charged up within .05v of each other. Pretty impressive if you ask me.

These are the way to go for balancing battery packs over 10ah.
