I had to try and convince a co worker not to use batteries with torn and or no wrapper, he's not a vaper, he's using motorized camera mounts. He insists on not wasting the batteries he split up from a bundle What does everyone think about using heat shrink tubing to rewrap? I think it doesn't sound half bad, it'll curl up around the insulator and hold it in place. Hey I'm trying. And btw they're 18650's!
