My battery making progress (Mostly photos - to keep them in one place)

PS: Spotwelds dont look as promising as they hold, but they do their job. - Passed the pull test I ran out of black and red wire so i had to use this blue and green one, same thickness, altho less copper strings. At the end of the pack the 5th wire is for the bms. Everything is double insulated( kapton and fishpaper) There is two layers of fishpaper in the middle of the pack. 12S4P P42A Should be good for about 100A safely.

This is the thread containing all the pics i have
