Super sub-ohm

[awj03130]

I know this topic is going to generate a lot of flames, but does anyone know of anyone who partakes or partake themselves in sub 0.2 ohm building?

I personally know a few people who are on the bleeding edge.

Not Bleeding Edge, pure stupidity

I guess I just don't see the point. .6-.7 is one thing (even that's lower than I like to go), but when you approach .2 you're pretty much working with a dead short. I mean what's next, just running a straight piece of Kanthal between the two posts??

When I sub-ohm I aim for .9-.8 Ohm Dual coil...seems to produce the best flavor & performance for me.....

i have various atomizers set up at 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and a few higher. i honestly dont notice much of a difference between them. i find that once you are below 1.0, performance really doesnt vary too much. battery performance sags on the 0.5Ω and below, but it evens out because i run those batteries down to around 3.5v instead of my normal recharge voltage of 3.7-3.8v.

anyway, what im trying to say is that i doubt a 0.3 or a 0.2 or even a 0.1Ω coil would offer me much that im not already getting. Sony does make a 50A battery (its a 26650), so going below 0.1 is possible and might not even be that unsafe, but i just dont see the point. the flavor has got to be severely sacrificed and the heat of that vapor cant be pleasant. im trying to imagine what i would gain by going any lower in resistance- and i just cant come up with any benefits.

What's the main objective? The biggest clouds or the lowest resistance? There's a limit to how low in resistance one can go, but there is no limit to how big clouds one can create. Reducing resistance to chase bigger clouds is a major misinterpretation of Ohms law.

 

[Kemosabe]

i agree. air plays more of a factor than resistance does in regards to clouds. and once you open up that air hole too much, your flavor will drop off (it does for me anyway). a moderate sized cloud with plenty of flavor is how i roll. im not about to sacrifice flavor just so i can marvel at clouds. if i want to marvel at clouds, i can go outside and look at the sky.

I'm sort of one of those people, I've done many really low ohm builds, a couple in the sub 0.2 ohms. I really have to stress battery safety, only batteries i use are the sony vt3 and vtc4's. They both do roughly 30 amps continuous, and are kinda safe at as low as 0.14 ohms. While saying all that, i can't really recommend going that low, but if you do your free to ask me any questions. Anything i can do to help people stay safe is always a plus.

I figured that luke-warm was the best response I was going to get. I would hope that if any new vapers are reading this, that they would understand how dangerous this actually is and how little of a margin for error there is when it comes to battery safety. Personally, I have even thought about using LiFePO4 batteries to increase my safety margin. I will say, I have seen some very very very low builds online, and it makes me nervous.
As for purpose, its pure cloud chasing. When it comes to builds, the heat definitely plays a factor. I actually run quad 1/8" air holes to compensate for the heat generated. To me, it would make sense that the importance of having the lower ohm level would be to generate more heat and then add in more airflow to get bigger clouds. In my builds, batteries are ALWAYS dated, production and cycle matched VTC4s or MNKE 26650s. Batteries are voltage checked before and after charging for correct voltage levels and are not charged on some feneric charger. Every build is checked on an ohm reader first with cap on to detect ohms and shorts. But I still haven't gone as low as I've seen some go.

To note, Leo, the inventor of the dragon coil and tiger coil is both a big proponent of battery safety and drasticly low sub-ohm building. Personally I tend to hover in the .5-.2 ohm range in mechs and the 1-2.5 ohm range for vv/vw.

Keep it coming guys. I appreciate the general civility of the responses to this touchy topic!

Absolutely true! I personally build three types of coils:

reliable non-battery draining ones (in the kayfun)

flavor-junkie coils (diamond, tinman, etc usually in an atty with reduced chamber and AFC - aka the trident)

And cloud-chasing coils (stupid hot with gigantic air holes, post holes, and much decreased flavor)


It's been my experience that there is a definite trade-off between flavor and vapor generation.

Hope you got some good battery's and play it safe if you do decide to do so. I know it's possible but far to dangerous for something safer that can be done to produce the same clouds your looking for. (Drilling larger holes, 100%vg, slow and long pulls ect.)
But they all most definitely will be on a bleeding edge if decided to do so, and they're battery blows in they're face, have third degree burns on they're vaping hand, along with mod and battery shrapnel piercing through they're cheeks and lips.
Sounds like the joys of vaping to me

We already have several multipage threads how sub-ohmers are going to ruin vaping for everyone. Is the super sub-ohm the new ruin vaping for everyone; does higher sub-ohm gets the green light now?

I'm using a vct4 and it's safe to .12 ohms. I don't go that low but I have made a duel coil at .3 which from my .6 single gave same results on cloud. Altho flavor loss was like 80%. To have big ... clouds then you must have big ... lungs.

The required massive airflow kills flavour too much for me to bother.

Also I really don't enjoy the different flavour from lung hits.

~.4 is as low as I'll go for a nice all day vape.

I could be wrong, but i was under the impression that this thread was started to discuss super sub ohm vaping, see who actually does it and exchange thoughts on the subject. So far this thread seems to be serving its purpose unless i missed something.

I agree. I am happy with this thread's progress. It seems we all have a camp, I just wanted to provide a fair playground for the exchange of ideas. I side on the low side, others may not approve of sub ohm or mechs at all.

What do we know factually and historically? If we exchange information and experience in a neutral manner (hard for me to do), I know we can all benefit.

So can we park the warnings and get some real discussion going on...

Why does you ... have lungs and clouds?

 

[Denrock316]

There was a guy on a nova Vape.tv show last night rockin a .077 ohm build with 1/4" air hole. It was a total white out.

 

[TrolleyVW]

My usual daily builds are ~.32-.4 ohm dual coils with 3/32- 7/64 air holes. I use VTC3/4s and I would say I'm well educated on battery safety and all. I have built a quad coil at .23 once with dual 1/8th air holes and the flavor was almost non existent, even with a 50/50 blend. At least with my 100 VG in my regular builds, I can taste it pretty well along with satisfying vapor production.

I guess I personally don't feel the need to build lower. For me, it's added stress on my already stressed batteries, blowing through juice, and unsatisfactory flavor.
