Hi and welcome,
The pre builts should have a resistance listed.
Where did you source the coils?
What is the metal they are made of? (SS, kanthal, Ni80?)
What is the nicotine level of the juice you are using?
With a decent pair of batteries, your SMOK should be fine up to about 120W.

18650’s and typically 70-80 nothing to extreme
No, they are asking what batteries specifically are you using? Manufacturer and model number. Not all 18650 batteries are created equal. Each manufacturer and model have their own specific capacity and current ratings.

You need to know how your batteries perform and what they are rated at, to get a reasonable suggestion for your resistance, that is why folks are asking. Because, if you want to mount two somewhat exotic coils (each coil HALVES the resistance, not doubles it) you may wind up with a low resistance build by default, depending on what you are starting out with. To make matters more complicated, the more mass in your build, well there's more surface area for flavor and vape production, so some folks find them more robust and to produce a better vape, but if you do use two exotics, it's not all about resistance, the mod may have to work harder at a higher wattage to be able to heat the coil sufficiently.

Given your wattage preferences so far, I might suggest starting with a single coil, period, if your atomizer allows for that option as well as for dual coils (many do/can do it) to experiment as you won't be messing with two coils and two wicks at all times, and you may find you really like the vape with one coil.

Just a thought. Typically (although not always) some of those prebuilt exotic coils can have a somewhat low resistance. If you can figure that out (it may have to be by building one) as well as what batteries you have and where you got them (and how much use they've seen) you may be able to get more specific advice, right now we kind of have to go on generalities and etc.

Best of luck,

Anna

... I have a ... smok alien 220w box. I’m not sure what ohms my mod should be running with a dual coils any help would be appreciated!
Your SMOK Alien is a regulated mod. (It has a micro chip or electronics; a mechanical mod has no electronics.)

When using a regulated mod, coil resistance (ohm rating) is irrelevant. Coil resistance is only relevant when using a mechanical mod.

What also is relevant is the type of wire the coils are made of. Kanthal, stainless steel, nickle, or titanium? The type of metal determines whether you can use wattage (power) or TC (temperature control) mode on your Alien.

The specifications of your batteries determine how much power your Alien can produce, in particular the amp rating specification.

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, you're 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.

WATTAGE PER SINGLE BATTERY:

Up to 45W:
Samsung 18650 30Q, 3000 mah 15 amp CDR
Sony 18650VTC6 3000mAh 15 amp CDR
