So. If I have .2mm copper strips with the nickel tabs spot welded to it. Could I take a 30mm wide copper strip and fold it to 10mm wide to increase the overall area and amp carrying ability while keeping it less than 18650 width. In the future I'm looking to do a 30q pack in the 8p size or more. But that puts you above 160a. Granted it's not a continuous draw number. I'm wondering how well some of the large P copper welded packs you guys have made are holding up and what kind of amp draw you're able to pull.
160 A from 8p30Q is a bit ambitious.
it might do it for a second but the sag will make it not very fun and you will be trashing the cells.
12p is another matter
my copper packs, 22s 12p and 18p 30q are holding up nicely.
