Everybody here needs battery packs for foiling.
Many build these packs their own, wondering how thick the nickel strips need to be, how hot they will get, and if they even need nickel or if maybe steel is enough.
From my perspective, many people go way overboard on the thickness and most people could just use steel, from electric point of view at least (for rust, pure nickel may be better).
So was I, and that is why I made this caluclator.
Give the calculator inputs about your pack, like S&P Cells, Cell resistance, Strip width, … and get information about dissipated power and thermal increase of strips and cells.
From that, you can make an educated guess, which thickness is enough.
