In the process of building a 16s4p (Molicel p42A) battery pack, rated to 120 Amps maximum (80 amps continuous).
I'll be using a Sunkko 709AD spot welder to spot weld (maximum 0.15mm pure nickel). I plan to get a large pure nickel sheet, to cover both the series and parallel connections, as shown in the attachment
I am trying to calculate the maximum current this will be able to handle. We know that each 0.15mm2 of nickel can carry 1 amp (0.15mm2 per amp). So the nickel sheet which is 80mm wide and 0.15mm thick has a cross-sectional area of 12mm2. This means it will be able to carry 80 amps! (12mm2 / 0.15mm2 = 80amps).
Therefore, layering two of these sheets, one on top of the other, would give me 160 amps between series connections.
Is my math correct on this?
