2026-09-01 (Tu) EleKSCo REV05 Battery holder wiring

I wanted to start wiring with a simpler component, so I chose two battery holders for 18650 and 18350 cells. The battery terminals I bought had little barbs to keep them from slipping loose, but I squished them flat with pliers to make them removable. I cut wire pieces the length of the battery holders and soldered them to the springy negative terminal. I stripped and soldered the wire’s other end to the barrel connector’s sleeve, heated some shrink tube over the connection, then screwed the terminal into the printed holder. There was just enough slack to mount the springy battery terminal and push the wire into the groove. The positive terminal was exposed, and I thought I could just let the battery’s cap push against it, but that seemed like a bad idea when I saw how malleable the connection terminal was. There was not enough room to hide the wiring behind the positive battery holder terminal, and even sliding it into place was too tight. I think that adding a few millimeters to the front of the holder will work.

The wiring sticks out too far
