I've been testing some prebuilt packs of 32650 lifepo4 cells, and then got a deal on some loose 32650 lifepo4 cells. As I understand it, the lifepo4 cells shouldn't need cell-level fusing as is often recommended for 18650 cells.
My system will be 24v (8s180p). I already have a decent battery powered spot welder. My plan was to spot weld nickel to the batteries and then solder those to the large twisted copper wires like many powerwalls have. Alternatively, I may use flattened copper pipe in some places since I have a decent amount already.
Other than pure nickel strip, what else could I use to connect each cell to the main twisted copper wires?
Despite the fact people can successfully not blow up a battery with the right solder technique, I think I'm going to avoid that. I think that limits me to nickel strips?
