18650 case with integrated cable clamp

This is a case for 18650 batteries I'm working on.

Beware!
18650 batteries are dangerous if handled incorrectly, because they can deliver a lot of amps. For instance: when accidentally shorted, a single battery could dump 100 Watts over your tiny hookup wire, which will burn of the PVC sleeving, starting an avalanche of cables turning into uninsulated conductors. Result: fire.

Now, this happened to me just a week ago working on a prototype, and I'm a professional. So I designed this case where you can insert the cables and clamp them on the inside from the case. It still needs to be able to adapt to different situations in rapid prototyping so there is no fixed polarity and there is mounting point in the center (30mm between holes).

Beware that the bolts still have power on them, don't let them get into contact with your electronics unless you want to. I added some bolt caps that work for me (hex bolt) and allow another wire insertion point, but you might need to create your
