Using this: http://coiltoy.ermeso.com/

5 wrap 22ga 2mm DUAL coil comes out to 0.09 Ω

Using this: http://www.onlineconversion.com/ohms_law.htm

You will see that:

0.09 Ω at 4.2 volts (Fresh battery) would draw 46.66 amps and 196 watts

It will work, but I wouldn't use it.

If that button gets stuck down by accident in your pocket you are doomed.

Aren't the 30a Efests supposedly really only like 10a or worse? The 35a ones are the 20a true rated...

Unless you are using a 50 amp 26650, that build is not safe IMHO. Add a wrap, 6 wraps each side.

Safe? Absolutely not. Doable? Yeah. I'm not advising you to use it but with battery sag, conductivity and whatnot, you're not putting 4.2V into that coil. Using a pulse rating is very unsafe, lots of things could happen causing your mod to fire longer than a few seconds or without your knowledge.

@Lenny Bee Hello and welcome to Vaping Underground....I hope you see these wonderful people's advice before you go too crazy with that build.

It's not safe at all....pushing that battery past 30 amps into it's "pulse drain rate" is like playing with fire. When you pulse a battery above it's continuous drain rating or even constantly push a battery to is max continuous drain rating it puts stress on the battery and will cause it to heat up quite rapidly....and after every time you fire it under a "pulse" condition you have to let it rest and cool down....to many pulses in a row can wreak havoc on your battery's health. It can not only rapidly heat up the battery but it also can stress the battery increasing the battery's internal resistance. Increasing your battery's internal resistance will not only shorten your battery's lifespan but also decrease your battery's storage capacity (drop it's total mah it's able to store per charge,) and along with that it will cut down it's performance making it not able to put out the amps it was capable of putting out before you stressed it making your battery work that much harder and the potential for something to go wrong that much greater.

I am not saying that if you do vaping something will go wrong...I am saying however that the potential for something to go wrong is a very real possibility. To vape something that low you need a 26650 battery with a 50 amp continuous drain amp limit if you're going to attempt it with a single battery mod. In reality you need a multiple (two 30 amp continuous drain or three 20 amp continuous drain battery setup) wired in series with a mosfet unregulated box mod to even come close to firing anything that low with any degree of safety. Preferably you should get something regulated that can fire that kind of wattage so you have multiple safety protection features involved because like @5150sick said...you're just a button getting stuck or one chain vape too many away from overstressing the batteries pulse limit and having the battery vent and bad things happening.

You don't have to build that low and take those kind of risks to blow huge clouds if that is what you're after. The resistance of a build is just one aspect of several factors that contribute to cloud chasing. I can blow the same clouds with my old Patriot 1.2 with a .76 dual coil build on my rDNA 40 set between 25 and 35 watts with my Pyrex Affinity Glass Cap I have for it with 1/8th inch holes as I can with my Mutation X V2 with a .24 single parallel build on a mech with the airflow open on just one side and almost as good as when I open up both sides of the MX V2.

Your coil's wire type, gauge, inner diameter, wicking material and the amount there of, coil position in relation to your airflow and type of airflow vent, size and shape of your atty's chamber, and diameter of your drip tip or the lack there of and the diameter of the opening in the top cap to put a drip it in as well as the power being applied to the coil and how it's being applied whether it's unregulated or not all hugely contribute into the size of the clouds you can blow as well as your lung capacity....and I don't care what anyone says....even with the best airflow that kind of wattage is just going to fry your juice and be uncomfortable to vape.

I am not telling you what to do, all I am saying is there are many thing that come into play trying to blow a big cloud, I know that's what you're trying to do because no one vapes at almost 200 watts "for the taste" and I am telling you there are much safer ways to do so without doing something scary risky like trying to run that coil on a single battery. It's just not safe.

thats definitely not safe and you need a accurate ohm meter. .04 difference can be a huge deal the lower you go.

I think it's great that you asked first ! You got some great input here, so in a word..."no"

Another suggestion would be to maybe try 24ga kanthal. 22ga takes a lot longer to heat up and it also takes more people power to heat up.

if it takes more people you are doing it wrong lol
