Comment on Drilling and tapping LiFePO4 battery terminal practicality?
sobchak@programming.dev 2 months agoI don’t think those would work for these large batteries. I have one that I use for small cells though (i.e. 18650/21700).

OK, I’m no expert but it says this at the end of that product listing:
Are you saying they need a heavier gauge bus bar for the current, something too thick for a small spot welder? Would you MIG/TIG weld a battery contact?

Yeah, these are 0.5C cells, meaning they can safely discharge 157A (I would be using them for offgrid solar), so those little nickle strips would melt. I think TiG welding these would be extremely dangerous and produce too much heat (and I’ve never TiG welded before; just badly MiG welded a couple times). By “welding” in the description they mean commercial laser welders.
