In every VV/VW mod I have ever used, the device does great at delivering the voltage you ask for, so long as the output voltage does not exceed the battery voltage. So if you set your Vamo to 4 volts, it does great while the battery has a nearly full charge. When the battery dips to say 3.6 or so volts, you see the output drop. I have observed this with a Lavatube, a Vamo, and an eVic. I assume this is true for all of the 33Hz mods.

This is not true with a ProVari. The output is constant from the first puff to the last puff.

In addition, it isn't true with devices that have Evolv products in them either. (ok, to be picky, the DNA20 isn't until 8 watts and up.)

I don't have experience with the Nivel Chip nor a couple other higher end products sold and haven't studied up on them.

Does anyone vape sub-ohm using a regulated battery device?

My pro-thingy won't fire anything below .9 ohms and my Semovar won't fire anything below 1. I don't know of any that will fire the .6 out lower that it seems many build.

Many people buy the wrong batteries for vv/vw mods, they use weak discharge batteries and run into a weaker vape when they start running at 3.6-7v. The batteries when fresh are @4.2v and will be a few volts higher at any control setting due to it delivering 4.2v.. The board @4.2v is happy about the extra volts its getting and runs more efficiently, then when the battery hits its voltage run standard and long @ 3.6v it drops the amp load to the board and now the vape is set to standard. The vv device has not gotten weaker its now running at its standard spec of voltage; some batteries like the sony 30a batteries do not move off 4.1-2v for a long time then when they do drop to 3.6v its highly noticeable and a user would think it is the device -- its not the device its the batteries settling at their standard run rating of 3.6-7v. Batteries are made to run at that voltage and run there for mah hours on end.. The device was enjoying the extra power as yourself, nothing is weakened about the vape at any point its the batteries. A provari just has better regulation processing and is why it cost premium bucks.

That's what I thought. I'm trying to follow the logic. So if someone were vaping sub-ohm, it would be a fair assumption they are using a mechanical?

Do people vape sub-ohm because it give them more control over their vape?

Not really. It may give more variety to the vaping experience, but as far as "control" (if we assume they are using a mechanical) the batteries used in a mechanical are unregulated, meaning there is no mechanism to regulated the voltage, so there is less control. The voltage goes down as the battery discharges, that's like a law or something. To maintain the same output (watts) in an unregulated device the resistance must be adjusted as the battery discharges or you need to put in a fresh battery. You could also put in a Kick, but I'm not getting into that with this example.

Again that has nothing to do with subohm and everything to do with mech vs regulated.



They are not just theoretically possible, they are fairly common and growing more common. But even if there were only 1 example, it would make your statement false since it does not necessarily mean mech.

What regulated mod runs sub-ohm? I have not heard of one that runs much below 1 ohm, and none at all that run to 0.5 ohm. An example, please, of this fairly common practice you have knowledge of.

Of course, the sub-ohm coils on a regulated mod are theoretically possible with the proper device...but 99.999999 % of the time the sub-ohm people are using mechs.

They are not just theoretically possible, they are fairly common and growing more common. But even if there were only 1 example, it would make your statement false since it does not necessarily mean mech.

"Fairly common and growing more common" If there was only 1 example it wouldn't be common and would make your statement false. "Common" is too vague a term to be probative.

There are some mods that have, say, 4 amp or better output capability. These mods will not trip as quickly as those having 2.5 amps for example.

Thus, when we apply the ever mystical laws of ohmage ;) we find that:

1 ohm resistance is the "division line" for the topic. So anything under that is considered "sub ohm", yes?

1 ohm resistance at nominal 3.7 volts is 13.7 watts of power and 3.7 amps as well. We can also use the "top end" voltage:
1 ohm resistance at top-end 4.2 volts is 17.64 watts of power and 4.2 amps. You could use even higher voltage too, but I'm using representative voltages here since single battery mechs are common.

Of course, as ohms decrease, the amps would increase. So you could decrease the voltage too. But that's chasing your tail (pardon the metaphor ocelot and Lion).

going to .6 ohms at say 3.7 volts is 22.8 watts and 6.2 amps.

So that gives you a rough idea about how the device specs fall out for "sub-ohm".

DNA20s will run into the .6 ohm range, evercools may be able to go even lower. The Kick 2 runs subohm coils. What, .6 to .99 is not subohm suddenly? lol

Of course, on regulated mods, subohm resistance is largely irrelevant and it boils down to power.

For those trying to follow along: I quoted a post here, but it was deleted along with the original post.

How about you refute my statement with evidence. I will gladly apologize and take back my statement. Calling my logic ** doesn't make it false.

So why is this practice fairly common? I don't know anyone who does it. Sub ohm lends itself to mech mods, which are not limited by power regulation, which is precisely what Atty was saying. You aren't making a lick of sense...

There is no evidence needed to prove bad logic. You quoted the proof of your lack of logic right there.

Will you apologize for it? I'll have to see it to believe it.

Anyway, not that I have to, nor do I wish to feed the fire at all, but I'll clarify my "theoretical" statement to mean...be as powerful as mech mods...like the .3 ohm guys and tons of watts.

Such devices may exist, and some that use higher sub-ohms do exist as pointed out, but the point is they are as yet a fairly small percentage of the whole.

Thus, for the OP's point, we discuss pros and cons as generalities.

Because people can? When people get a DNA20 and hear it can do subohm, many try it. I can think of at least four youtube posters off the top of my head that have done it on camera (pbusardo, tomzgreat, marc puno, bishopheals) , and quite a few posters on ECF have done it.

Well at least you knew what I was talking about. That ought to put out the fire, but it won't. Apologies are due, but won't be given.

As for this clarification, "tons of watts" is subjective, and of course it would make no sense to limit the term "subohm" to .3 and below. Which is why, as my first post in the thread said ... high wattage is the issue.
