So not sure exactly what sort of copper? Maybe the pads are made of. But the spot welds are suuuuper sticky. Can’t pry up even one weld. I think solder would help. But I dont think it is nessesary. But time will tell.

Fair enough! I know nothing about that PCB system, so I’ll assume that BioBoards did their due diligence with designing it

I’m sure you already thought about it, but you can add some heatshrink around it

Dam u swapped to copper braids now,ugh and i got alot of 12awg wire i was gonna use for my upcoming 12s20p but now seeing these braid builds makes the pack much thinner i want copper braids. Always making me jelly from these clean builds but it does teach me wat and how to go about setting up my own

I wouldn’t say swapped to permanently, I found this really good, superfine strand copper braid, its much easier to work with and retains its flexibility much better then other stuff I’ve used. Silicone wire always a good call! But if you are looking to save a few mm of space, braid is the way to go.

Surface area is key. And this one offers alot of it.
Right, thinking i might do 3 braids for each p group to handle all the current

12s20p is a huge pack, what is your layout? You might be better off spotwelding super wide nickel
Its gonna be two 12s10ps gonna do a standard 12 group flat double stacked layout. I am getting some wide nickel so i can cut into a 10 cell shape then spot weld another nickel tab over the 1st and fold it over. It probably sounds a bit odd from the way i explain it but tldr itll look similar in design to how u setup packs XD

I already did a scoot pack upgrade before so this is definitely a board build XD

Looking forward to seeing this! 38x10 still seems a bit small for 12s20p but, what do I even know 
DOOOOOO ETTTT!
