Super safe. No protection needed. Readily available anywhere. Last a long time.
Here is a link to the first PUCK I made. It is now retired. http://www.e-cigarette-forum.com/fo.../409519-puck-single-battery-pack-4aa-mod.html

I'm showing an unmodified battery holder from Radio Shack next to the completed box mod.
The larger terminal on the left is negative. That's where you solder the black wire from the pass-through.
The smaller terminal on the right is positive. That's where the red wire from the pass-through is soldered.
I can't show you the wires from the Fasttech pass-through, because I don't have another one. If you build it, you will need to take a single edge razor blade and open up the main cable to expose the wires and cut them short for soldering. The beautiful thing with this mod is that you only have to solder two wires. Very easy!
Good luck! A very satisfying build.
Here's a photo of "The Rocket" in my hand and being activated. Fits nicely and feels better than the original PUCK I made using a standard Radio Shack 4AA battery box.

I was before I saw this thread thinking of doing a home build as FT put up all sorts of goodies like USB charging boards, battery holders and all sorts of interesting premade modules for Ard stuff, I was working on modding a crash helmet with an automatic kind of feed pipe but ended up ruining a crash helmet when a battery shorted due to the damp UK weather lol
I actually tried it last night and was successful. However mine is more along the lines of the battery holder being in my pocket, and the ego is still on a long strand. I'll probably eventually make it more like yours
Exactly what I was thinkin'...
I'm actually thinking about using some heat shrink tubing on each battery to hide the obvious. It's pretty tight already, so this might not be a valid approach. The other thing I'm thinking is to simply remove the existing plastic wrap around each battery and expose the metal.
yeah, thats a bad idea....
if you want the look, get clear battery shrink....
the outside metal skin of the battery cell is the negative, you don't want to short out the batteries with tools or loose change.
Sorry for the post to an "old" thread, but I wonder how that passthrough would work on an 18350 in a pipe.... hmmmm...
I have really been wanting a fixed 3.6-3.7v e-pipe lately. The passthrough could really be the answer to that on a DIY pipe mod.

You must provide something close to 5 volts for the passthru to work. It assumes you are connecting to a USB port, which is 5v. Don't try to use it with any other voltage, as it won't work.
I can only go by what the expected input voltage is, which is 5 volts based on USB levels. As far as the electronics inside, I can't say.
