I am working on a project and I now have to connect 150 Amp battery packs in series. The previous person working on this used Nickel. I am more inclined to use Copper. Does anyone know the advantages and disadvantages of either one. Also I wanted to make a type of busbar connection between the packs but I do not know how large the material connection needs to be (thickness, contact area, width).
The total battery connection in series is 75 Volts and each pack is 3.5 Volts.
Any advice is greatly appreciated.
