Yes my Cardassian friend. Much typing lol.
Do I look like a cardassian who would run from a fight? ...Don't answer that.
He he he. Did you think you could get off that easy? Since the OP was unsure of whether or not a VV/W device was safe to sub ohm, I'd say you have a rather large obligation to explain to the OP exactly what "knowing what your doing" consists of with a mech.. No cheating by linking to other pages, you opened Pandoras's box, Have a vape, you're gonna need it. You got some typing to do...... LOL
Very well...
WARNING: EXCEEDING THE AMP LIMIT OF A BATTERY WILL CAUSE A SHORT. AND SHORTS ARE BAD. OKAY?
Before attempting to use a mech mod you need be very familiar with ohms law, Amps ( I [current]) = Voltage (V) / Ohms (R[resistance]). Additionally you should be familiar with the extended version of Ohms Law: Watts (P[power])=V^2/R. Knowing this will make mech vaping a much more enjoyable experience than fiddling around with builds until you get it right.
EDIT: The basic form of Ohms Law has endless application when building for a mech because it tells you how many amps your build is drawing once you stick it on an ohm reader and get the resistance of your build. If you're using the most common batteries, 20 maximum continuous discharge rating (MCD rating), and your reader tells you you're working with a 0.3 ohm build then:
Amps = 4.2 (a fully charged cell, be safe, don't try to account for sag or inefficiencies) / 0.3
Amps = 14
You're completely safe. 0.3 ohms on a mech is also a nice vape.
Now, if you build very low, like 0.1
Amps = 4.2 / 0.1
Amps = 42
And you're having a bad day because there could be an exploding battery in a hard metal tube in front of your face when you take the first hit.
You also need to familiarize yourself Li-ion battery safety and mechanics. Specifically the rather obtuse C-Rating specification. It's rather infuriating. C-Ratings are how many times its capacity it can discharge safely and has to do with a battery's mAh rating. This provides an amp limit for a battery.
Additionally, you need to know about battery construction since, shockingly, sticking a powerful capacitor in a highly conductive copper tube without knowing too much about the terminals of a battery or where on itself a battery can ground out is a pretty bad idea. Li-ion batteries tend to explode or superheat and vent hot electrolytes when short-circuited. A sufficiently low resistance build can do the same thing. Hence the reason for needing to know Ohms Low like the back of your hand.
All of this is just the basics. You'll also need to know about battery sag, specific heat, heat flux, heat capacity, internal resistance, mod resistance. The list continues.
I don't really know how I didn't vent a battery when I started vaping looking back at how little I knew when I got my first FUhattan.
Basically, you have a regulated mod. Stick with it unless you feel like trying a mech out. Do a lot of research before ever buying one.
