So wanna build a new deck with MAD hubs, Focbox unity and a 12S4P battery with samsung 30Q battery’s.
I wanna use the Jet Vulcan Rocker 36,5" deck and it think this is the best battery placement for it.
But whts the best way to weld the pack? Weld all the 12X4 parallel packs and use 12AWG wire to make the serie connection? or weld everything and bend the cels and nickel strips inside (180° bend).
Generally bending the nickel 180 isn’t recommended, it will break from the stress and cause hella issues. Use 10awg where you can and you should put wire along the nickel so the nickel only carries the amps from a single cell
If you can, yes. Cut a strip that is 8 cells long and weld it on the one end of each row and 2 4 cell long strips on the other, if you can you should connect between cell 1-2 and 3-4 from each parallel pack but one wire between 2-3 should be fine
Other option is weld short tabs on the end of each cell and solder a single line of wire along the tab, it will make the pack have a smaller footprint and it should be strong if you strip the wire in the middle instead of 7 small sections. You can bend it around at the connection between rows safely but it does add a few mm to the height
