Variable voltage mod that can handle sub ohm vaping?

Just the fact a provari can vape 1ohm makes me want one.

Actually, for piss-n-giggles, I set my ProVari @ 3.9v with the 1.0 ohm dual-coil in my Hercules yesterday evening. It's been running great since without any errors. :) I've read that ProVape underrates their regulator, and it's true. The ProVari V2.5 is rated at 3.5 amps, but I'm running 3.9 amps / 15.2 watts. Not too shabby at all IMO.. ;)

Many regulators seem to be able to go a little above rating. Word is the provari seems to have a limit right around 15w regardless of output amps.

Most of the Chinese regulators don't.. I had a sigelei ZMax which wouldn't run to it's rated specs at all. Watch some of PBusardo's reviews of many of them on his scope... 15 watts is all I'll ever want or need regardless.. :)

We actually don't have the specs on the Chinese regulators that I've seen. I'm talking about manufacturer documented ratings for the regulator itself. Curious though, how did you run your Zmax up to 4-5 amps?

The Sigelei wouldn't even run a 1.3 ohm single-coil at all without an error is my point...

What is the rated spec? Your provari comparison was on rated amps, and I don't know how people run the zmaxes up to their rated max.

It's supposed to be 5 amps...


5 Amps or even bigger current

Protection against short-circuit

Output Voltage: 3.0~6.0v

Wattage from 3.W-15W

I finally hit found my Sweet Spot.

DNA20D Bogger Box
Reomizer 2
Wick is Rolled 400 Gauge Kanthal encased in XS-116 sheathing
4-3 wrap 27 Gauge Kanthal
Ohms is coming out to .60 and it's vaping super smooth at 20 Watts

Also Vapes Superbly on my Standard Bottom Feeding Bogger Box

To me the lower Gauge Kanthal Provides a Smoother and Less Hot Vape then the higher gauge.
The DNA20D is providing rock solid consisten Vape.

This is my taste preference, I understand others may differ.

Many out there using .5 ohm micro coils on mechanical with a charged battery at 4 volt would draw 8 amps. I am not into sub ohms and try to stay in the 1.4 to 1.8 ohm range.

Talking about the Zmax.

You should really try wrapping a high resistance coil. Build the atty completely the same but wrap 28 gauge say, up to 2.5+ ohms.

Right ... how would you even reach that?

If it's using the same chip as the Vamo, stacked batteries bump the amp limit up.

OP: THROATHIT TWIN 18650 V V MOD

Despite his spiel in that post (he says 2.5A so people wouldn't keep turning the voltage up and destroy their coils) his mod has close to a 5A limit (4.7A on mine).

Happily runs a 0.7ohm coil @ 3.3V (15.5w), and if you can bear to move up to 1.3ohm it'll deliver 25 watts fairly easily @ 5.8V.

Built like a brick [word-ECF-mods-would-whinge-about]house with two AW 1600mAh IMRs inside (though you can request other batteries if you like]. Last time I checked for someone in the US he said it'd cost £110/$175.

It's a good mod. I have one I purchased last year (or maybe longer) @ UKV... :) I only don't like how the charging port is on the bottom. I had to cut a piece of foam material to make it sit flat. Also, the larger RBAs are kind of awkward on it. Other than that, it is a good performer.

Is that a vamo board?

I don't think stacking bumps the limit unless there is a separate switch in the buck portion, but it does make it more possible to reach the limit. At 6v, 5 amps is 1.2 ohms. Can it fire that?

No, it's not a Vamo board...The 5 amp limit is from the dual 18650 8.4v battery holder's PCB, which has these specs:

*Overcharge (>8.4V)
*Over discharge ( <5.0 V)
*Over drain ( >5.0 Amp)
*Short circuit protection


The ouput power is controlled by an Omeg linear potentiometer...


EDIT: Corrected battery holder specs for ThroatHit Mod...

Ok so not relevant to the Zmax discussion.

If the Zmax uses the same chip as the Vamo (an awful lot of links on the net say they have the same chip, but some Zmaxes don't allow stacking, some do...apparently), so that's how the stacking would work.
Remains outstanding performance in stacked mode 18350, 18650 in the mode almost the same on ProVari. Were measured: 14.9 W 3.3A in 18650 and 25.9 W, 4.3 A in 18350 Stacked, and this must not be the limit, I was just not suitable evaporator to explore the lower limit.

I thought he was saying his Zmax couldn't reach that limit though?

I had a Sigelei ZMax which wouldn't run to it's rated specs at all.

TH mod was for OP, totally irrelevant to Zmax discussion.

Already kind of went over this. The question is, how do you output 5 amps on a zmax?
