It is about three month since I started vaping. I just bought a TFV8 cloud beast and then I realized that if I vape at 0.15ohm, 100W, it is gonna be 25.82A. My question is, I am currently using the LG HG2, and it labels Continuous Discharging Current: 20A. Is this means I can't use HG2 if I am gonna vape at .15ohm 100W. If so, what batteries should I use?

Resistance doesn't matter if you're using a regulated mod. The calculation is:
Watts (add 10% to account for device inefficiency) / battery cutoff voltage = amps
Divide the amps with the number of batteries (parallel and series work a bit differently from each other, but the amp draw per battery is the same). 20 amp batteries are good for about 60w per battery.

I don't know what mod are you using so I can't check your numbers. But exceeding a battery's CDR is a bad idea.
Tell us which mod you are using and we can provide more info on its capabilities.
As KenD said, multiple battery mods change the calculations as opposed to mech mods. With a mech mod you have only battery voltage to deal with and it's usually a single cell. With dual and triple battery mods the batteries are usually in series and the cumulative voltage can be used to regulate the output through a regulator circuit that synthesizes output voltage.
A two battery mod can provide 7.4v (2x3.7)and a triple battery mod can deliver over 11 volts (3x3.7v) at nominal voltage to the circuit that feeds the coil. That changes all the numbers and puts less load on the actual battery power source. Even if you use the cutoff voltage of 3.2v for calculations it can still safely provide high wattage at some level all the way to cutoff.
It's a little like using a lever and fulcrum to lift a weight easily that you couldn't possibly lift with just your arms and back. The batteries supply power to a circuit that is capable of providing high output current to a low resistance coil by regulating the combined capacity of multiple batteries. With the batteries in series, that's a safe and easy way to provide that current with relative safety.

As previously stated above, we need to know what mod you are using.
The formula you used was for a mechanical mod. The formula is different for a regulated mod. Calculating battery current draw for a regulated mod
Regulated mods use buck/boost circuitry which can boost the final power output artificially. Two and three battery mods also increase the available power output. All the variables must be known before giving a proper answer to your question.

I don't know how you got 25.82 amps.
100 watts is about 16 amps per battery when they are discharged at 3.4 volts.

I think I used the method which calculate the mech mod. Can I know how you calculate the regulated mod? It's just confuse me. Like if I vape 100W, 0.15ohm coil on my H-priv 220, what current draw will it be on my batteries?

Thank you Mooch, but I am still confusing. For example, if I use 0.15ohm coil and vape at 100W on a regulated mod, like SMOK H-priv 220,
Thank you, I think I understand how it works a lot now.
resistance does not matter for regulated mods.
Just a general rule of thumb that I like to use..
A single 20A 18650 can usually handle around 60W without any issues. With that RoT in mind you can just double or triple the wattage for dual / triple 18650 mods (ie: 120W, 180W)
