In Search of the Most Efficient Coil Build

[MoonRaver]

I been vaping for over a year now, off the tobacco for roughly three months. Started out with the run of the mill Aspire, upgraded to a nautilus mini a few months back. About a month ago, got my hands on a cheap off brand Chinese Terminator APV and am now enjoying the freedom of being able to make my own coils.

Atm I'm using a dual uprights using A1 24awg Kanthal testing in at .18ohms. Not sure if the build is dangerous. I think the battery (Sony VTC4) can handle it. Any suggestions?

So, I plan to check out what this forum has to offer about some future builds I plan to use. Looking to make the most efficient in terms of power consumption, vapor production, surface area and flavor.

I would personally not go that low on any single battery mod. The VTC4 is a great 20A battery that can handle 30A but gets really hot really fast in the 10A-20A range. With that build you are running 23A which is a little high for my comfort level, but it is technically within "safe" limits. I am more concerned that you are running builds like that without KNOWING if its safe or not first. I highly recommend some studying on battery safety and Ohms Law. @Baditude has some great info in his blogs on these 2 subjects. Also take a look at the bench tests performed by @Mooch which can be found on his blog!

Why build that low if you've only been building a month? What is the mod? You said the name, but even google isn't bringing it up. Regulated or mech mod? You should read up on battery safety and ohms law instead of guessing if it's safe or not. Assuming you're on a mech, that's roughly 23 amps. While the VTC4 is a 30amp continuous discharge, you still shouldn't push a battery that hard without knowing about the safety behind it.

I'd move up to 28g until you learn about it the safety and all with what you're doing it.

That's far lower than I'd go, even on a two battery parallel box. If that's a single battery rig-- you said "battery," not "batteries"-- I think you'll be better off in the .5ish range.

That is the link to the unit I'm using at the moment.

As for the reason for going so low, I had a hard time not smoking while using the aspires w/ 24mg nic straight menthol flavor. The current setup I have seems to cure the itch. Though I did find myself dropping to 18mg nic.

I'm going to look over those documents you guys listed so I can understand your reasoning.

Thanks for the info guys.

Thats pretty high nic content for a low resistanc build as well.

Because you're new I guess the link won't show up, but I found it for the people who want to see.

How much did you smoke? at 0.5 ohms on an Atlantis at 24w and 18mg was enough to get my dad to stop 2 packs a day.

About 20 cigs a day plus my homegrown Havanna which is very potent after work.

will 1.0 ohm be noticeibly better than 2.1?

Depends on the surface area of the coil. I just jumped up to .51ohm from .18 and I'm not liking it as much. Seems I like hot vapor. It just goes to show, everyone has their preferences.

I would imagine it would get hotter.
Xd I'm still in training.

This is about a .25ish ohm build with 24G N80 wire. 3mm ID, 6 wraps each. Much safer (about 17A), and it chucks pretty good clouds. Even in that plume veil. Do your research. Nichrome 80 is a lower resistance wire than Kanthal. It heats up faster and saves some battery power, but it will throw your resistance down super low if you don't put enough metal in your build. Check out Steam Engine to get an idea of how many wraps and what diameter you need, but I wouldn't go any lower than .25 ohms EVER on a mech. Too many things can go wrong.
I would suggest 10 wraps @ 3mm ID. About .35ohms and about 12A. But that's as low as I would be comfortable on a mech for a beginner.
