Follow the specs of the device?

on the sub-ohm tank (if thats what you're using) each coil on the side should provide a recommended wattage to set the device to. Using a regulated mod you are much safer as the chip regulates power to the tank

Regulated power devices have functional resistance ranges, batteries have continuous discharge rate (CDR) expressed in amps.
As long as the resistance you intend to use falls within the power devices operating resistance range and the cells you use have a suffeciant CDR to safely support the watt range you intend to use, you should be fine.

Only use authentic cells purchased from reputable dealers.

As you should be...First thing is to familiarize yourself with Ohm's law regarding batteries and the proper resistance to build to according to said batteries capabilities
on a regulated device, resistance doesn't come into play when figuring out amp draw....

what mod and batteries are you using?

Pretty much the title.
I really want to start super sub ohming, (don't ask why) and I'm scared of battery venting/exploding

Since I can't ask why you want to start super sub-ohming, let me lay some knowledge on you: When using a regulated variable wattage mod, there is no logical reason to use super sub-ohm coils. Simply increase your wattage setting instead for the same "effect".

Before there were high wattage regulated devices (just 3 - 4 years ago), the only way to sub-ohm ohm was to use a mechanical mod. Today, you have nearly unlimited wattage power with modern regulated mods, eliminating the "need" to use a mech and sub-ohm coils.

The dangers of using a mech with super-sub-ohm coils are twofold. A mech has no electronic protection circuitry to prevent hard shorting the battery. Many many misinformed mech users abuse their batteries by using builds that are outside the safe parameters of their batteries. A misinformed user of a metal tubed mech is a pipe bomb waiting to happen.

So what can you take away from this? Your regulated mod's protection circuitry will probably prevent you from using a super-sub-ohm build (<0.1 ohm). If you try, the chip will display an "Ohm's Too Low" message. Your mod has a lower limit in resistance that it will fire a coil; you can probably find that number on the manufacturer's website or in the vendor's specifications for the mod.

You are going to be limited by the wattage setting your mod can do, and also by the batteries you use.

Are you using a single, dual, or triple battery mod? In the interests of keeping things simple:

-If you use a good quality 15 amp CDR battery like the Samsung 30Q or Sony VTC6, then you are good up to 45 watts per battery; 90 watts using two; 135 watts for three batteries.

-If you use a good quality 20 amp CDR battery like the LG HG2 or Samsung 25R then you are good for 60 watts per battery. If using a 2-battery regulated mod, your good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.

-If you use a single 25 amp CDR battery like the Sony VTC5A, then you are good for 75 watts per battery, 150 watts for two batteries, and 225 watts with three.

-If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with a pair of 30 amp CDR batteries you could safely do 180 watts.​

I believe that device has a 3.0 volt (don't have one, so I'm not 100 percent sure)
it's also a single battery mod, to figure out amp draw you take maximum wattage/battery cuttoff

so 85/3=28.3333

if you run it at 85 watts all the time, you'll need a 30 amp battery.

if you run it at 50 watts max, you'll need a 16.666 amp battery and so on and so forth.

ETA: baditude explained it much better. lmao

Also, I don't know exactly what "super sub0hming" means. Your mod will only fire down to its lowest resistance, and honestly I'm not in love with "the highest OR lowest my mod (supposedly) can perform as I feel that pushing any mod (not just mech mods) too hard is not the greatest idea. Although, the "build limitation" should in theory keep you safe. Keep in mind that the coil (drop in and/or self built) will change in resistance over time, usually from the beginning. So if you say, build a 0.1 coil and it converts to 0.08, say (although typically resistance will rise, but not always) you aren't leaving much of a "safety margin" etc. You'll also need the right batteries, but Baditude covered that quite nicely.

Then (unless you are using unflavored and 0 nic and max VG because you want to get cloudy, solo) you'll have to address your eliquid and nicotine strength depending on what happens with your wattage. You'll also burn through wick and/or coils faster.

So, I'm not going to ask "why" I just really wanted to point out that there will be a lot of variables to consider You'll also be consuming a lot of eliquid and ejuice if you are "supersub0ming" and do you have a particular resistance in mind?

It can be done sort of safely I'd just not recommend redlining anything. I generally don't though, recommend that.

Your specs say mod will fire down to .06Ω. With single battery device that's just a waste of power imo.

I agree. The lower in ohm you go, the higher the amp draw from the battery.

1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.15 ohms = 28 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohms = dead short = battery vents or goes into thermal runaway

What will happen to you on a regulated mod is simple. If your coil is less than your mod is rated for it won't fire and you'll get some sort of warning. It happens to me all the time.

I have a couple old mods that won't fire below .5 ohm. Sometimes I'll grab the wrong atomizer and pop it in without thinking and it won't fire. So I dig around for a .5 build.

If the chip is reliable. I have a VCT that will fire below it's rating.
