You know your resistance and you can Google the max amps your batteries can supply. An ohms law calculator can tell you the theoretical max watts if you have those numbers.
Since you have 2 batteries you can roughly double that in the way your batteries are configured in your mod.
Note that batteries don't enjoy supplying their max amps output, especially not for longer periods of time.
Eg. do the research and find your answer so when your resistance or batteries change, you can calculate it again. It's not hard if you done it once or twice.
And do some reading on batteries, there are plenty good write ups to be found on them.

You're good for up to 120 watts in a dual battery regulated mod with 20A batteries.
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.

He's running a regulated mod, so the coil resistance being used is irrelevant.
Using a regulated mod, you use Watts Law, not Ohm's Law.

OR.....you can crank that baby up til it tastes bad and then back it down till you find that spot you cant live without. Thats how i do it anyway. Right now, i have my voopoo drag set at 140w running the octo coilhead for the smok tfv12 king. I get a very nice flavorful and cloudy vape . Resistance is .15 on this thing, btw. As far as batteries go, i have 2 in it. Lol. I run it til the batteries get below half and pop in 2 more freshly charged. Regulated mods, i never worry about batteries. I just vape the hell out of em and switch out when i need to.
This, Just because your mod can go high doesn't mean it has to, I vape in the same range as your .2 and I vape at 70 watts, sure I can bring it up to 180w but I don't because the vape is too hot and there's a massive loss in flavor.. Start low and turn it up until you like it, it's that simple.
The 25R is a 20 amp battery. There are two variants denoted by the colour of the wrap, both are great cells.
List of Battery Tests | E-Cigarette Forum
A 20 amp battery is good for 60 watts down to the average voltage cutoff of most mods. Two of them is good for 120 watts. The coil resistance is not a relevant factor to this on a regulated mod.
The known tested specs of all the batteries we use is available thanks to Mooch's testing.
Abusing batteries and pushing them beyond their spec is a terrible idea, and there is no good reason to do it.

It's good that you are asking about safety and batteries, and you've gotten tons of useful information, I hope you find it useful.
I will just add, regardless of how HIGH your mod can go, are you satisfied with your current vape? Because, getting the highest amp batteries to try and go to 120 watts, you may not enjoy the vape, and your run time will suffer.
I'm a MTL vaper (meaning low wattage). For me, that means putting in the HIGHEST available mAh battery just decreases my run time. It's one or the other. So, if you've found a satisfactory vape, match your batteries to your habitual wattage. If you do that, you won't strain the batteries and you will have more run time.
Should you decide high wattage is for you, great, and there is no reason not to experiment with going higher. However, if you find a better vape a lower wattages, matching your batteries to yoru wattage is, over the long term, going to give you the best battery life. The higher wattage you run, the more you sacrifice run time. Etc.
Best of luck,
Anna
