and yet my question remains…
given this construction what are your welded nickle strip recommendations…?
Your suggestion relies on those 3 pieces of nickel being a solid unit. In reality, you are only going to have a stable connection to the top layer of nickel

I would join the 2 cells with one strip, and then give each cell two tabs. The tabs should come away from each cell not directly on top of each other, but slightly separated so that the solder from your series connection can be in contact with all 4 tabs

Interesting suggestion, I’ll take that under advisement… but back to your solid unit of nickle… how about if I weld the nickle strips together under where I make my series connection… would that not make my nickle a more homogeneous unit?

It would be fine if your series connection came from on top of one of the cells but it would be tricky to weld the center of the strips.
It would suck to weld the center and accidentally weld into the negative cell casing

I tried this a couple times with used cells, 0.2mm nickel at 55 joules on the second layer, the fish paper charred a couple layers but the bottom facing the cell didn’t discolor at all. I think if you blow through both layers of nickel and the fish paper your settings are probably way too high

My nickel size isn’t on that list I use 0.2x15mm nickel for everything. 1 layer if I don’t span more than 2 cells past the S connection.

I have a seller to recommend if ya want. I’ve always gotten pure from him and he’ll cut a roll to any size. Bout a week lead time + shipping for custom sizes. Have to get 1kg minimum though.
Alternatively I can just sell you a bit of my 0.2x15 if that’s what ya looking for

Thia guy. If the size is not up there, just put in order notes what width you actually want and he’ll cut it up to that.
