This pack was not made for ESK8 but specifically for RC airplanes 90mm jets configured as an 8S2P pack using EVE 50PL cells.
I’m using an AWithZ P120D welder, but the same results can be achieved with other AWithZ models it doesn’t have to be this one. I’ll be testing the same technique with the P90C, 60, and P30C models as well. The copper brazing material is from my store.
The settings used are: only 30% power, gear 300, pre-heat 0.10–0.15, 2ms pulse, and double pulse mode.
As you can see, this is 0.3mm pure copper welded directly to the battery cell no nickel involved. I achieved a consistently strong weld. I do not recommend this technique for thinner copper like 0.1mm or 0.15mm, as they are too thin and won’t hold firmly in place.
The Idea is the same concept can be used for your packs. I am not sure what i the max current you need but with 0.3mm copper x 15 like this one is you can easy produce over 200A.
