> But now I want a power bank with hot swappable batteries/modules
I think it’s possible to build one. Get a bunch of 18650 cells from a reputable brand (or just an old laptop battery, if you’re brave enough), then look for a 18650 powerbank kit on AliExpress – some of these would be with slots you can just plug the cells into, without welding/soldering.
