Looking around for a single 18650 battery case, the only thing I seemed to see was the rubbery silicone stretch on type. Those are probably good, but I kept looking not finding anything until I ran across an old reddit post where someone said that a dime coin tube was the right size.
Some other folks tried them and said that they're too small, I figured I'd check it out and see for myself. BCW lists the size of theirs at 17.9 by 65.9 mm, and with 18650 batteries being 18mm or so and larger, you can probably see where this is going.
So, yes, they are too small. The tube gets smaller near the bottom, on a Sony VTC4 or LG HB6 it's just the last quarter of an inch or so, but on a Samsung 25R it's much farther up. You might be able to push some batteries in all the way, but I think they'd probably get stuck.
So, I sanded a bit until the LG and Sony would fit. It could be done a bit nicer, I was just seeing if it would work. The Samsung is so much bigger that I don't think it would work in these tubes, at least not without a lot of sanding. Maybe a different brand of dime tube would work better?
So, what battery cases do you use?
