Yeah, I wouldn’t charge it too quickly if it’s too out of wack, but this can balance it statically as well. It’s like a smaller/simpler BMS that does the actual balancing a bit more heavy handed. Most BMSs suck at actual balancing.

the difference in voltages in my pack is like 3.1-3.65 while the rest of the pack is at 4.07. Would it be able to bring that back you think, so I wouldn’t have to mess with all this other stuff?
That’s real low. Are you certain you don’t have a dead cell(s)?
To answer your question, I’ve plugged this into some suspect packs and it has always made a real effort, so I’d expect it to try to balance out your pack, yes. Whether it would be successful or not…

yeah I’ll have to double check on that I might be wrong. Hmmm, well thanks for the link man =)

how do you know where the pos and neg plug into the balance plug?
You just have to identify the cell and trace the leads back to it, negative on the negative end of the cell and positive on the positive end of the cell

Not to keep this going on purpose… but just ran across one of these possibly being used as a BMS in the wild.
@thisguyhere any idea how this held up?

i’ll have to check, it was a buddy’s build. probably be a while till i see him though. and he’s not the type that’s gonna open it up to measure voltages…

PSA: got me some legit nickel from Steel City Store on Ali Express. They have all different kinds and plated steel too so read carefully before buying. I got 30mm wide and 25mm wide. The 30mm x.2mm is particularly useful for them high amp cells
#Aliexpress US $24.50 30%OFF | 0.2mm * 30mm Pure Nickel Plate Strap Strip Sheets 99.96% pure nickel for Battery electrode electrode Spot Welding Machine
passed dremel spark test and soldering test.

aww HELLLL YEEHAW
Would anyone like to get some and distribute?
I can. How much would you want?
I have a bunch of 25mm x15 here if you can use that
Maybe 3m? I have 25x.2 on hand but I would like some but the 30mm would be nice for 21xxx cells

OK, I just ordered a full kilo. Should be enough to go around.
Check back at the end of July

Looks a little heavy to me but better than your sunkko ones
Maybe the left spot didn’t have as much pressure as the right one so it burned a little
That was 45J, so I dropped it to 35J and it seems nicer
