.1 ohm dual parallel build, safe?

[KingKut92]

Hey all,

I recently built a .1 ohm dual parallel with 24g kanthal around a 3mm screwdriver at 4 wraps. Set it up on an atty and put it on my mech. I was using Sony VTC4s and vaped it with no issues for a couple weeks.

I had no problems what so ever, but my inquiry is this. I've never built that low before, let alone on a mech, but how close am I cutting it to the danger zone? I don't fully understand AMP loads and how they range at super low ohms. Also, how low should I be vaping my batteries? I fuck up occasionally and vape my 18650s down to 3.5V with "safer" builds, what are my risks in doing so at .1 ohms? Curious as I want to start messing with dual claptons and I know depending on what wires you use they can sit around .1 ohms.

Thanks!

*Dual fused claptons

 

[KingKut92]

Also good to note that after a little chain vaping, the mod would be warm, is this normal?

 

[VAPEROXX]

Single battery mech?

 

[KingKut92]

Yes

 

[VAPEROXX]

What battery (ies)

 

[KingKut92]

Sony VTC4 (bought from lightening vapes) not worried about it being fake

 

[VAPEROXX]

You're lucky you haven't blown your damn face off yet. .25 ohms is really pushing the low end of the envelope.

[VAPEROXX]

You're drawing 39 amps from a 30 amp battery. Mech getting hot after chain vaping... well yeah...

 

[KingKut92]

I'm trying to avoid face blowing off as much as possible, should I just stop dropping down below .2?

 

[VAPEROXX]

Stick to .15 and above. .15 ohms draws 24.67 amps.

 

[VAPEROXX]

Or get a parallel box mod.

 

[KingKut92]

Now I am getting off the thread topic, but what about when I use this build on my series regulated box or my vaporshark dna 200?

 

[VAPEROXX]

And PLEASE check out the stream engine link I posted. Plug in your specs, and voila! No face blowing off.

 

[VAPEROXX]

A regulated mod is a whole different critter. As long as the mod can handle the resistance, you're ok.

 

[KingKut92]

Well thankyou for the advice, I pride myself on not doing stupid shit with vape gear, and here I was breaking my own principles lol. Thankfully I'm ok.

 

[VAPEROXX]

Yes thankfully! I love vaping and helping fellow vapers. Good luck and be safe.

 

[KingKut92]

One more question, what about this build on a 26650 mech?

 

[VAPEROXX]

Honestly, I'm no 26650 expert but, from what I know about them, as long as you have a quality battery, I think you'd be ok. @Mooch might know more about that than me.

 

[Bean8379]

Here is a basic understanding of Ohm's law. Voltage divided by resistance equals amps. The lower the resistance, the higher the amps. Why you would even use a mech without knowing this is beyond me. Why you would further endanger yourself by building that low on a mech is way beyond me. It is highly recommended not to go below 0.3 ohms on a mech. 0.1 is almost a dead short.

 

[trlrtrash13]

Hey, maybe we could insult his mother too. Then he'll really want to come back with the next safety question he has huh?

Anyhow, if your mod gets hot stop and check everything out even if you think it's a safe build. If it's just getting warm, that is often heat transfer from the atomizer. You will know that this is the case if the sleeve is warm but the battery and button are not.

If you want to vape that low, a good dual battery mechanical mod with the batteries in parallel would be a good idea. You're probably within the burst rating of the battery but that's not really how hard you want to push it with something that close to your face.
TT

 

[Bean8379]

If my intention had been to insult him, he would have been very aware of it. Sometimes people need to be made clearly aware of the danger of their ignorance. I'd rather he have hurt feelings than a physical disfigurement or worse because he blew his face off.

Dead short is below .1, it is serious dancing with Darwin... it is not if it will fail but when it will fail.

I mean some people want to mangle their faces with implants and piercings... I mean this is just a logical step from tacklebox face... tard ohm implants!! it is the future.


@KingKut92 Some advice from an old guy to a youngin...
If you need to stop and ask if it safe chances are it is not.
Stop for a second and consider if it is a hold my beer moment.

 

[OBDave]

As far as being nice when it comes to critiquing a bad idea, I've got to say even @BigNasty is on his best behavior here (by @BigNasty standards, anyway).

@KingKut92 - Don't vape that coil with a 26650. Don't vape it with a single 18650. Don't vape it if you're the kind of person who tends to accidentally draw their mech batteries too low. If you must vape that coil, do it on a regulated mod, or maybe a multi-battery mech box. Kudos for inquiring when you realized you were taking a risk, and for responding positively to the advice here. The part about visiting Steam Engine is particularly useful.

 

[BigNasty]

@OBDave No idea wtf is going on with me...



OH yah been sick.

 

[nightshard]

There are still so many "should I use stupid ohms and pull crazy amps with my mech" type questions around, and that's just in this forum.
A lot just do it and don't bother asking any questions.
Just imagine how many people around you, in your vape shops and hangouts, carry those new age pipe bombs

I "liked" this even though I truly hate how correct you actually are...

Well, I didn't quote you or mention you, so why did you reply professing your innocence when you weren't accused?

 

[Bean8379]

Whether I was being accused or not, I clarified my intentions. If you have a problem with that, I simply do not care. When I read a sideways comment and don't know who its directed towards, I treat it as if its directed at me and I address it. I'm a very blunt person. Like I said, if you have a problem with that I don't care. The above comment is only another attempt to antagonize. I will not engage in a childish argument. I've said my piece. Twice now. I'm done.

 

[iiKryptic-old]

Wholly shit, this is not even my thread and as I was reading I realized how much of a noob I am at this. I was running dangerously close to these numbers. You can call me whatever names you want as long as I am still in one piece....lol. Thank you guys.

 

[martinelias]

I've seen worse.

I was completely ignorant to how much .1 changes the draw on a battery. Time to put up my mech until I get myself better informed.

 

[martinelias]

Usually the more vapor you want to produce the more battery you're milking.

Wow....I guess Im touched by an Angel then .075-.09 daily vape on my StingrayX (Samsung 25R, no doubt)

It only takes one mistake or failure to lose a couple fingers or get badly burned...

O I know but as long as you know what your doing and have a understanding of the danger your creating and the limits of the products your using I dont see the problem, unless they danger others knowingly and/or act like they dont understand what went wrong afterwards to expel the blame elsewhere.

Even so, things fail when pushed to their limit, including mods and batteries. Personally, I'd rather have a failure at 7 watts...

This is exactly what I came to say, if you have a question about the safety, that is second guessing, it means you probably shouldn't do it.

Hard shorting a cell will most likely end in thermal runway no matter how low a build is and how many watts you're pushing. The fire button doesn't even need to be down. Effect will be the same either way.

To say that you can't or shouldn't build below a .3 on a single 18650 is bizarro world nonsense. I'm all about noob safety, but that's just overkill. At 4.2v you can build down to a .22 and only pull 19 amps. That's 58W vape vs. an 80W vape. Again i'm all about safety, but i'm against robbing folks of a perfectly safe & satisfying vape for the sake of fear mongering. Cheers

I'm all for new vapers with $15 ohm meters, or no ohm meters, vaping however they feel is satisfying, as long as they post pics of the aftermath when their 'calculations' or re-wrapped batteries fail...

 

[martinelias]

On a vtc4 you can go even lower, stress free.

Yeah, except when they're using a re-wrap and have no idea what the actual specs are. I use re-wraps currently, but I research the testing info, one is rated for 30A but falls off around 20, the other is rated for 20A but only good till about 10. Both are efest. I do not push the limits of my batteries, I don't see a need currently to go below 0.5 ohms. 0.3 ohms is a general rule of safety for noobs, but even those who consider themselves advanced should know the limits of their batteries. If you have a battery that can handle the amps and you know how to build coils safely, you can build as low as the battery allows. But for noobs I say first know your battery's limits and no matter what don't go below 0.3 until you get good at building.

Generally the only "aftermath" of running a
.22ohm build is a smile. It's no more dangerous than a .3 ohm build as long as the batteries are quality and they are properly installed on a fully functioning mod.

I never said I think .3 is safe for new vapers, either...

Here's a list of battery tests done by a member on another forum. Look up your batteries here and read about what amp limits are safe for your cell:
https://www.e-cigarette-forum.com/forum/blog-entry/list-of-battery-tests.7436/

And here's an informative video about battery safety:

Those should get you started on the right path!! Good luck!!

That would make sense if there was a consensus as to what "good at building" means. Because "good at building" to you is not gonna mean the same as it does to me. His build might be flawless, it might have just been a little too low for his education level. Again, all i'm saying is that this thread is misleading. There's a difference between saying "you should learn how batteries work before you do that" and "THATWILLBLOWYOURHANDOFF". Because honestly his first build would have already done that.....but it didn't. And now he's doing the right thing by asking questions, so i believe it's best to stick to the facts and leave opinions out. Educating people always works better than warning them. Or scaring them.

 

[Bean8379]

I disagree.
