Tesla 21700 positive electrode is made of aluminum

[@eckythump6429]

Maybe try spot welding with a strip made from a drinks can (alucan) as an experiment. You need similar metals to be able to weld.

Can try.

Hi. I have been trying to do the same with the same results. I will try an aluminum can. If it sticks then I will have to figure out how to connect the open end connection. Any ideas for that?

I made a 20s 10p with the same batteries, wasn't fun, wasn't quick normally run 30s,, worked out a easy way tho, I'll test that out soon if only they had cheap hand held ultrasonic welders
