That’s my biggest worry, I’d hate to do all the work just to have to redo it regularly, so I’m not attached to USB-C, that’s just the current trend and I’d like to build this idea to last.

The battery to tool converter is actually how I got to this idea. I live by the idea than anything worth doing is worth overdoing, so why stop at an adapter when I can just make my own interface and modify all future tools with that? It will look cleaner, and all I’ll need to do going forward is solder in the port for any new tools I get.
