Did you consider using double wide nickel?
I’m having trouble finding the right width and thickness combination so the plan was two layers of 0.1*20mm per cell to cell. The cells are P42A’s
Hmm yeah it does get complicated
I gotta say I freaking love these pre cut nickel tabs.
Also today I tried the thing with my maectrics where the positive lead stays in place and I go around with the negative.
And I like it…
With the pre cut nickel are you just going for one layer as it is 0.2mm thick ?
Cool welding btw.
Yep. Just one sweet layer of easy welding.
This is going on one of @BenjaminF PCB kit.
I don’t have the series connections done yet.
But it is this guide.
This bears no importance, but I thought it was cool and I wanna share…you can fit 2 of these 6s 5.8 Ah lipo batteries in a Meepo V3 battery enclosure…it leaves no room for a BMS or even wires but if you’re feeling creative you can
what is the point of the holes in the nickel?
are you sure about that. pretty sure that it can fit another row
dat is a lot of cells
50g?
The slot prevents a straight electrical path between the two welding electrodes, and thus forces the full weld current to go down into the cell and back up, rather than just going across though the nickel strip.
Makes for more consistent welds with better penetration for a given power setting.
(Obviously this only works if you put your electrodes on opposite sides, straddling the slot.)
ah cool
makes sense
thanks a lot
Shameless plug.
Not quite EU.
Yes, dude. New battery pack is comming
how many cells is that?
1130pcs, not all mine not wraped, but great price
wow thats a lot of batteries
11s100p?
Would like to dispose the balance wires as best as possible as so the wires don’t cross each other, at least the minimum possible.
Ended up with this layout due to enclosure constraints:
What would you guys advise me as a good layout for the balance leads?
