Hey guys, I plan to build my first battery pack – 12s2p Samsung 40T. I’ll have the parallel pairs welded by a friend because I don’t have a spot welder. I’ll do everything else myself though. I got 0.2/25mm nickel strip from nkon and I’d like to use it like this for both connecting the parallel pairs and for doing series connections by soldering 10AWG wire on the small surface at the top:
Does that sound like a good plan?
Alternatively, I could cut the 25mm strip into 2x 12.5mm and get those welded on rotated by 90 degrees:
That way I would get more surface for soldering but it would require more welds for doing the parallel connection. That sounds like more work. Would that be the better option nonetheless?
This will be for a street board and I assume average discharge will be around 10A with occasional 40-50A bursts.
