Solderless/Switcheless Heat Shrink Mod

[gib]

I was messing around with some heat shrink tuping and made a couple of battery mods that work surprisingly well.

I used heat shrink tubing from Harbor Freight

a battery connector. In this case a 808-D/901 connector from madvapes

The center post from an old cartomizer

a small piece of 3/8" pex pipe for the battery connector to fit into.

A thumb tack

a thin sheet of brass cut into strips

an old spring I had laying around

and something to mold the heat shrink tubing to the proper size. for the 18650 battery, I used 1/2" copper endcaps for the ends, for the 14500 I used a regular AA battery and carefully heated the tubing around it.

I am still playing around with the switch placement. Any suggestions?

It isn't very pretty but it is minimalistic. I like it. Throw on some sort of strip cover and rubber band to protect it in the pocket.

No suggestion on switch placement. I've tried various placements on the half dozen or so boxes I made so far and have so far concluded that in the end the ease of pressing comes foremost in the end.

Interesting concept you have there. I'll keep this one in mind.

Well it is pretty nice. Plus easy and inexspensive to make.

Thanks for the feedback everyone. I made up a couple more based on the switch being on top and I like the form factor better. the button is easier to push and they fit easier in the hand. I used a plastic tube on the 14500 battery one, it makes the battery easier to replace. I wonder if I can charge it while still in the case? The 18650 I used a mechanical switch at the top to see if I liked it, but it makes the mod bigger, not sure if i like it. I am still looking for a cleaner looking button.
I ordered some 10440 batts from Madvapes and am planning on making a teeny tiny mod with those. It won't last long but will fit discreetly in a pocket.
I like the size and weight compared to the other mods I have made (flashlight , fog log and nicostick) not to mention how easy and quick it is to make.
Sorry for the fuzzy pic. I put a 808 battery in the pic for size comparison.

That's comparable in size to the epoxy mod. Guess battery size would be the determining factor preference in both.

Interesting concept, Gib. From an experiment point of view, I like it.

But, if you ever get pulled over for speeding or a red light infraction and that thing is laying on the front seat or falls out of your shirt pocket -- you *are* going to jail. That is one sketchy looking contraption... <g>

HOW THE HELL WOULD YOU CHARGE IT?

Or are these disposable batts?
