Spot-welding Li-ion packs - charged or discharged? Answered
I'm making a large 18650 pack for my onewheel-like hoverboard build. It's my first attempt at spot-welding (DIY spot welder powered with a MOT, scary beast can melt entire M8 nuts on longest impulse time), so I'm afraid I'll mess it up. I was wondering... is it safer/more convenient to work on charged or discharged cells? Does it make any difference at all?
