noob ?s low ohms concerns

[SwaK]

I dont know if there is any code of conduct on this subject but I need someone to explain the risk of running low ohms.

I know that in order to run low ohms (lower than 1ohm) you would have to use a mechanical mod, so theres no type of circuitry protection. But what type are the major concerns are there? I know that when your running low ohms you run alot more wattage and your PV dissipates heat quickly. But if your practical about things, once the heat dissipation is obviously high, I would think putting it down too cool off for a bit would be an obvious step of prevention. Am I missing something or is there more to it than heat dissipation on the battery?

---Cliff Notes version---

SLR vaping (Super Low Resistance) does not work on regulated mods.

this is because such mods have protection circuits built in... these are there for a reason.

It's not about heat from wattage... it's about the discharge rate of the battery in Amps.

Basically SLR vaping draws more Amps from the battery in order to push more watts, if you go too low, or use a battery not rated for a very high discharge rate, it's essentially like shorting out the battery and could cause catastrophic battery failure

which... near your face... would suck

Well, I assume they use high drain batteries....so that will help some. That said....IDK if I'd want to stress a battery that much all the time.

It's good that you bring it up...but I think it's real a real specialized "trend" going on right now. They do use a heavy gauge coil...so they need the watts to heat it. Thick wire is also why the ohms are lower. But I suppose you could up the voltage too.

I think some regulated dual battery mods can push the amps too. That may be even safer...if they don't think it's a short.

I really am not that fond (at this point) of that trend...since it get's close to "short" status. To be fair...I haven't tried it either.

I think that "regular" gauge and ohms are fine for vaping though. And flavor is fine too. So why chase some other, more risky, endeavor? Others will disagree, I'm sure.

Let the "oh wow man, it's flavor" rants begin. Or maybe "more vapor"..as if we needed more. Or....whatever.

Drawing a huge load of current from batteries is hard on them and shortens their life. It also can burn out wiring, solder, and PCB's which may be inside. It can lead to failure (catastrophic or otherwise) in smaller cells. The larger cells you use in a mod are much better suited to handling this big current draw, and true mechanical mods have no wiring or solder. I don't know the exact mechanics behind the degradation which occurs in small cells, but it is a generally known concept.

What kind of battery are you using?

That's why the Mods we use for SLR vaping are "Mechanical" and have no wires, solder or PCBs, as it would absolutely kill all of the above

Let's be blunt...

That's like a Virgin saying they're not that fond of sex...

Let's be even more blunt....stressing these batteries with no need is.....unwise.

You are free to disregard my comment if you wish as my post count is currently 1, but I do have a fair understanding of basic electrical concepts.. What everyone has said thus far is true. You would draw much higher amperage from a battery with super low resistance atomizers and these batteries aren't designed to do that. Using a resistance lower than 1 (or so) is just shy of shorting out the battery which is never a good thing since for basic electrical system to work there must be a consumer (the atomizer..). You can use ohms law calculators (google it) to see what wattage a setup will put out and how many amps it'll draw from the battery. I don't know specifically what the limits are on a standard ego (or whatever) battery are, but play around with the calculator and you'll see certain values jump around pretty dramatically when you drop resistance way down..

Who dictates need?

I wasn't satisfied with what eGos or VV devices could do...

I'm very satisfied now... even cut my Nicotine level in half. Plus I save a TON of money rebuilding my Attys instead of buying consumer attys

I can build 6 coils for about $1... that would have cost me $30 before.

I'm sure a virgin unimpressed with the sex they've never had, doesn't see the need to risk disease or pregnancy.

Good post. Welcome to the forum!

Besides, after you're done with cigalikes, eGos, and have a couple Provaris knowing there will be no VW upgrade for them where else is there to go?

1st, great post... welcome to the forum...

BUT, That bolded statement is not exactly accurate... there are several batteries available with C Ratings higher than we are pushing... So by definition they ARE designed for it... yes, you could screw up a coil and get a hard short.... or an inexperienced vaper could use an inadequate battery.

but SLR vaping CAN be safe if you know what you are doing and use the right devices/products

 

[AttyPops]

Yeah, but you've yet to explain WHY you would want to do it at all!

Coy comments aside. Why?

Without going SLR, I had to reduce resistance to get more vapor... but then, it increased heat... Increasing voltage would do the same, but also burn juice...

SLR allows for More vapor, cooler vapor, more flavor...

basically the perfect vaping experience... all the things that I found lacking in every previous attempt with every previous device I tried in 14+ months of vaping.

Atty, I sometimes go below 1 ohm tho most the time stay around 1.1 ohm, it isn't something that people seem to understand til they try it, but it really does give a different vape than even using a lr at 4.2.

It also is not something to be done lightly, as in you CAN NOT use an ego for vaping like that, you have to watch what you are doing I won't even trust my 1.1 with an 18350 as it is pushing too close if I get a hot spot or a short, and well we all know that every coil everyone wraps comes out perfect every time lol

 

[AttyPops]

I'm not trying to be "Anti-SLR" or something. It just seems easier to get within a standard ohm range by using more coil wraps and maybe a little thinner wire. You can make it as hot or cool as you like with VV. The more wraps increases the surface area.

This reminds me of the whole dual-coil thing. Cooler but more surface area. I understand that amp limits are a problem this way when you want to push the wattage.

But...is it much different than what people get with DCC's and VV ?????

A four amp device at, say, 6.0 volts is 24 watts and well within the rage of many PVs with regulated circuits. How many watts does it take for SLR? And by that I mean...what is commonly done?

 

[ClippinWings]

To the OP....

I would suggest that since you even call yourself a noob in the topic title...

DON'T even consider SLR vaping yet...
Go through the gamut, use the options available, read... watch videos, read some more...

Then decide if it's something you're interested in...

Look at it this way... Look at my signature, I didn't start SLR vaping until WELL after I had been vaping for a year...

Not until I was 100% sure that nothing else was satisfying and 100% confident I understood the risks and rewards.

I suggest doing the same.

The AW IMRs are able to handle the drain of the low resistance. From the tests I've seen online the 18650 can handle a continuous discharge rate of 10A and the 18350 can handle 6A. Which is why I don't run lower than 0.8 ohm on my 18350s and I run my 0.6 ohm setup on my 18650s.

Here's the info I found:

Test of AW IMR 18650 2000mAh (Red)

Test of AW IMR 18350 700mAh (Red)

May I ask what voltage?
