so I got more then enough LiPo pouch cells and want to make a 10S2P pack.
After trying to solder them - which failed miserably I´m looking for another way to connect them. A spot welder seems to be more expensive then buying a ready battery pack. Did someone try a mechanical connection?
i dont know as I’ve never used aluminum solder but 80 watts, if i’m correctly remembering, is good and high. if you search there’s people who’ve done it. mine’s 80 watt and is definitely good for lead solder and up to 10 gauge wire so the tabs with the right solder should be good.
Check my thread on how I made my lipo packs slimmer, I linked some flux core aluminum solder which I used successfully on a 60w iron. It comes in a green spool, purchased on Amazon US
The solder wasn´t sticking to the tabs even after sanding them. Not entirely fresh. Quite a lot experience in soldering normal connections and SMD PCBs so this shouldn´t be a problem.
