| LATE EDIT:
The photos do not show the vent holes placed in the bottom of the finished mod.
ALWAYS VENT A METAL MOD. EVEN WITH "SAFER CHEMISTRY CELLS"
HERE IS AN EXAMPLE:
http://www.vapeatron.com/attachments...17-26650-2.jpg
The 2X2 is finished and before I top off the charge I just have to vape it a little while. Dual carto mods might seem a little strange, they are, but you don't have to use both ports at the same time. The extra unused port is a really convenient place to measure actual LOADED voltage.
I used the same aluminum box (from MPJA.com) but put two 801 to 510 adapters in it (from Heaven-Gifts.com). The center contacts came from old 808D-1 cartos as did the insulators. The switch came from allelectronics.com and the battery, a 26650 came from batteryspace.com. The protection circuit is a 6 to 8 amp board from DealExtreme.com.
If you look close you will be the areas that had to be relieved with a Dremel to make room for the 26650 and the two connectors. The connectors are pressed in but also rest up against the side of the box and are epoxied in place for both a little extra strength and insulation.
Little spots of epoxy are placed at strategic locations to prevent movement and insulate. Two of the four screws that hold the lid on are cut short to clear the 26650 at the bottom end.
Look it over, ask questions, and No I won't make one for you 
Next comes a parallel 18650 aluminum box, but with a single 510 connector and a new way of mounting it.

| As always Rocky, very nice. Love the pics. The button looks like it would be more natural or comfortable on the front, rather than the top. | |

| Charging is provided through connector port with operate switch strapped down?
Control board is clearly marked and comes with a spec sheet? Board grd is common to case and batt. neg? Any source for a protected 26650?

Some think the protection is not needed but a short circuit would "vaporize the switch and wires". Batteries with tabs usually aren't "protected".
The positive lead just senses battery voltage. The board goes between the battery negative and "system" negative so it can sense current flowing through the 2 parallel/back to back mosfets. The brain turns the mosfets on or off.

| Dont just take rockets words for it..
I have vaporised some 16g wire on my alagatorclips by accident during inital load testing, i mean, short due to wrong clip in the wrong tab... 2x26650 serries.. it was hot fast and lucky i had a pair of dikes with in reach.. | |

| Nice, but why the 808 center contacts?
Kinda hard to tell from the pic, but would standard batt connectors (+/-) and mounting the switch in the box (not on the plate or top) fit? With a single atty.
My choice for extra protection in a single cell PV. Littelfuse/2920L300DR 5A trip
FWIW these connectors. 
Are great (but a little awkward to use all the time). Very well made with great threads and the insulator doesn't just sit under the center post but is large filling the whole diameter of the shell, from wall to wall so to speak. I can't these getting pushed in. On the bottom where you solder is a nice hole (not all the way through) in the center contact, makes for easy soldering and a very strong joint. I needed them for a special project.

the 808 insulators are better than most "connector" insulators and the tube is easy to solder (actually already tinned).
A regular connector would fit, and switch could go in box instead of lid, 26650 stills needs a little bit of dremel room in this box.
The box is not a perfect rectangle, the lid is bigger than the other side, more working room.
and you gave away my "Secret Connector". I have a few ego connectors and cones coming from China 5 for $7. You can cut the bottom off some to give more internal room, drill a 7/16 hole in the box, ream it out just a little and lock it down with a cone on the outside. A little epoxy on the inside to stabilize and seal the ego connector if you have to take the cone off for some reason. Would probably also work for plastic boxes. But the box thickness would prevent using the ego mega atty in place of the cone, or a tank. Would work for 'almost' all cartos though.
EDIT: reread your questions. adding a battery +/- holder/connector would be really really tight. the 26650 almost fills the box.

| JJ,
here's the drawing for the box I used. There are other sizes. http://www.mpja.com/download/16283bx.jpg
The only problem with ordering all the parts is finding the stuff at one vendor at the cheapest price. Doesn't look like that will happen so add other "necessities" in each order
Going to bed soon, will reply in AM.

I somehow would trust it, for an emergencey over those cheesy, cheap protection circuits... No?
I needed those connectors for a special project per some requests. 
A nice heavy duty PT, solid Hammond box, recessed horn, tiny LED and the best USB cable I could find, 22 ga power wires. Big difference in performance over my mouse USB cable one.
FWIW those 510-> eGo adapters are pretty crude. Took a little work to get the eGo cone on (thought maybe it was a different thread) and right out of the box a standard 510 bottomed on the collar and didn't make contact. They are adjustable though, took some tweaking to finally end up with the small collar gap that should be there. 
They are the 2 slot, I got mine from GoodProphets. They have a carto like slotted center post that may be useful for some applications though.

| Sorry about the dig on the "plastic box" .
A good plastic box will last and is less work than machining an aluminum box. You are absolutely correct (as you have pointed this out to folks many times) that a passthrough looses voltage as the current goes through the cable. MJPA has a 5 volt 4 amp switching supply/wall wart with a dc connector. Seems to have 20 ga wires in the lead.
The ego connectors I have coming (maybe by Thursday) are the ego battery connector with the hole for a button not the adapters.
The cheap protection boards that give people the most trouble are the ones with a single mosfet chip. the ones with two mosfets won't trip until about 6 to 8 amps which is fine for a 26650 twice pipes or running a dual coil at 3.9 volts. Just something to keep from melting the switch
The fuse or the protection circuit, one or the other , is a good thing to design in. You never know what is going to happen.
When are you going to put up your tutorial? We're still waiting
Have a nice one, I'm off to the sack.

| Update:
2X2 is all charged up.
Unloaded voltage is 4.22
With a single Dual Coil the loaded voltage measured at the empty port is 4.03 volts.
I'm sure it will fall under 4 volts pretty quickly though.
That's about the same loaded voltage I had before with regular cartos.
The 26650 ain't feeling no strain yet.
Maybe I'll build a 3 port mod so I can put 2 cartos and have a empty port for the voltmeter.

| Well I don't know about the 'port' volts.
When checking loaded volts in a box mod, probes at the cells show the highest, after the switch a bit less, at the actual connector inline with the atty less yet.
Hey Rocket can't figure this out. Same company has a switch listed as. Another is listed as. Quote:
3A @ 125VAC
2A @ 30VDC for silver
| About the only info I could find is that with DC, volt-amperes = WATTs ?????

| The parallel port is the same as putting meter leads on the connector, no current is flowing through the parallel connection so no voltage drop from there to the 'in-use' carto connection. 18 ga short connections between the two 'ports'.
The switch ratings for AC and DC also depend on wiping action of the make/break action and contact force. UL has some guidelines for rating AC/DC current and voltage. If the ratings aren't typos then some factor in the design drives a different rating for AC vs DC. The VA rating is usually used for contacts that are "plated" with silver or gold. The current density through the contact will melt thin plating. Tach switches are often rated this way.

| I bought some of these but haven't used one yet.
Would be pretty easy to put a hole in the box then blend it with a ball mill and let the roller stick through just a little. Sort of a 'light touch' mechanical switch. Or even take the roller off and glue a pretty bead on the lever. Small and has a 3 amp rating.
EDIT: Rated 5A 250V

| It's a 3 amp 125 volt AC rating but I bet it would work with most e-cig applications.
Here's one with a smooth bead instead of the roller.
Probably could use the SPDT to switch battery between carto connection to vape when pressed, and charge from a charger when released.

| I used one once. The snap actions are supposed to be some if the most reliable switches made.
The problem I had with a ball/lever type was they were way too easy to activate unintentionally. I ended up gluing a tiny piece of carpet foam under the lever. Worked out well, trimmed it a tad to get just the right amount of extra firmness.
Certainly cheap with great specs and 'Life' ratings. SS-5GL: OMRON ELECTRONICS: Electromechanical
Seems like it's probably one of those in Cisco's 26650 Helix. Without the lever or foam though, as folks always comment on the extremely light, short activation.
When the SuperT guy was talking about a 26650 future PV his switch specs for 'Life' matched up with the Omron.
