So I am looking to start spot welding 18650 batteries for some project and have no idea if there is a standard width and thickness for 18650 battery strips.
I've seen widths from 4 to 10 mm and thicknesses from 0.04 mm to 0.3 mm.
Will be buying a 10 m roll for future use and found a source of pure nickel strips instead of mostly nickel plated steel found on the market.
There is no harm in going for a thicker strip right? Just a cost and weight penalty?
What do you recommend?
