yep. most of the safety rules like ohms law and whatnot are only important in unregulated mech mods which is not what you are using. you should be able to below .2ohm and well over a hundred watts with the gear you have now
First of all, coil resistance is irrelevant when you use a regulated mod, which the SMOK Alien is. What matters with a regulated mod is the wattage setting that you will be using.
The Samsung 30Q is a 15 amp continuous battery, which works out to about 45 watts per battery; 90 watts with two. Samsung 30Q 3000mAh 18650…a great 15A/20 battery!
So, if you keep your wattage setting below 45 watts per battery (or 90 watts per dual batteries), you'll be fine with the 30Q's. If you want to go higher in watts, then you need a battery with a higher continuous discharge rate.
20W-45W:
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 and the wattage doubles. If you are using a 3-battery mod, you're good for 180.
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.
Note that if you go with a 30A battery, you pay a hefty price in capacity (1500 mAh). You'll get about half the run time as a 20A battery.

Why is the resistance irrelevant on a regulated mod?
Good question. I'm not schooled in electrical engineering, but the answer lies in Mooch's explanation in the link I supplied above. Mooch is educated in electronics and designs electrical circuits for the government and private business projects. He has the equipment to bench test batteries and has earned much respect in the vaping community.
"Calculating the current being drawn from the batteries in a regulated device can be very confusing. You can't do it the same way as you would for a mechanical/unregulated device and there are so many different battery configurations; single, dual parallel, dual series, triple series, etc.
The way I keep it all sorted out is to remember that, in a regulated mod, the coil isn't connected to the battery. The regulator is. To calculate the current being drawn from each battery when using variable-wattage (VW) mode you need to calculate the maximum wattage each battery supplies." --Mooch

The regulator microchip lies between the battery and the coil, and alters the output to the coil by using either buck or boost electronics to alter the power output to the coil. Buck circuitry drops the power output to below the battery voltage available. Boost circuitry increases the power output to above the battery voltage available. The regulator maintains the user's set output (wattage) to remain the same from a fully charged battery to the low battery cutoff point of the chip.
It's a different story with an unregulated mechanical mod; coil resistance IS relevant. There is no regulator to adjust the power output from the battery. It is a direct current from battery to the coil. Therefore, there is a gradual, constant fall in the battery output as the battery is used from fully charged to the point where the voltage available can no longer fire the coil. The only way to adjust the output to the coil is to change the resistance by using a different ohm coil.

No, your formula is for Ohm's Law and is only good for unregulated mechanical mods.
Regulated mods use Watt's Law.
Max Amps Per Battery = Max Wattage Per Battery / Minimum Voltage Per Battery
Mooch explains this in the video I posted above. Watch it.
I had that question for a really long time too, actually. But, it is in fact correct that as long as your mod is capable of firing a low resistance coil, what is going to matter is how many watts you apply to the coil to get it vaping. I think the confusion sometimes comes from the fact that often, the lower resistance the coil, the higher wattage that may be needed to get a satisfactory vape (which is not 100% of the picture, actually, as sometimes the build itself (single or dual, type of wire) will require more wattage to heat it up than a more simple build. So a lot of factors will affect what wattage a coil is vaped at including personal preference and type of build.
However it is true that with a regulated mod, what matters to the battery is the wattage drawn from it, not the type of build. Period. I'm not saying this at all elegantly, but you can vape different resistance coils with the same wattage, and while the outcome (vape) may be different, the circuitry of the regulated mod will be doing the identical same thing-- drawing energy from the battery to produce wattage, so you need to be concerned with wattage w/r/t battery, although certainly, different resistance builds or even just different builds will all affect taste/flavor/etc.
With that said, given the wattages you wish to run at, it sounds like you are in a reasonable target range for that. Which is what matters-- that you aren't overstressing your battery with higher wattages than you want given the build in your atomizer.

Because on a Regulated Mod, the Atomizer is Not Directly connected to the Battery. There is some type of Circuit Board in between.
So the Atomizer "sees" the Circuit Board. And the Circuit Board "sees" the Battery. And it is the Circuit Board that draws Amps from the Battery to Raise/Lower the Battery's Voltage to make an Output Voltage that will be sent to the Atomizer.
