A friend of mine bought a used electric bike as a project that had a 24v battery that was knackered. The battery was an unusual shape and it had pouch cells in it. He re-celled it using modern 18650s and is happy with the results.
he used this welder that comes as a self-assembly kit to weld the nickel strips, and he said it worked very well. He used slotted nickel strip that I advised him to get from Nkon. I think the slots help a lot to get good welds. He also used ring insulators and other insulators plus heatshrink from Nkon. he had never done anything like this before, but he does have good general practical skills.
