Specifically, on Na-Ion batteries:

I sat with battery technicians and both helped and did it myself, soldering the straps between lead acid cells with a gas torch (oxy/acetylene torch) and nothing but a blanket over the cells.
This was replacing singular or multiple cells in electric forklift batteries because a whole new 48 volt battery was worth a fortune, replace dead cells only and every strap was soft soldered together.
