Nickel Strip Spot Welding and configuration for a DIY 12V- 3S16P Tesla Cell Battery?

[Jbroscious]

Hi all. Looking to see if i need to double or even triple up on nickel for spot welding my Tesla Cells to make a 12V battery using 3S16P configuration?

I have 8mm of 0.15mm nickel tape at the present. Can i get away with doubling up only making it 0.30mm for proper amperage distribution?

Also would like a diagram of how to set up the nickel strips for my welds for the 12V- 3S16P layout?

Thank you
