You won't get to 200watts on two of those that's assuming your coil could take that heat also.
Assume you'll get 18A (always be pessimistic) and base worst case of batteries down to 3.2V (standard cut off).
200W you would need over 30A without pulsing and possibly overheating the batteries.
There are no 18650s that are rated for continuous discharge of more than 30A.
You could use 30A batteries but you're really pushing them.
With two of the batteries you mention (rated at 20A continuous) you could safely go up to 120W and some would say maybe 140?
You probably won't like it though and if you're after "clouds" you don't need to use high wattage.
For 200W you need a lipo battery pack or at least three high amp batteries.
