Two stacked, unprotected high drain 18350's = starting output voltage of around 8.3-8.6V
One single unprotected, high drain 18650 = starting output voltage of around 4.1-4.2V
The power dissipated by a resistor (the coil): P = V^2/R:
a 3.0 ohm coil will get:
P = (8.3^2)/3.0 = 22.963 W - Two 18350's
P = (4.1^2)/3.0 = 5.063 W - One 18650
These number change immediately when you hit the button because it is dependent on Buck/Boost circuitry!
but draw is what we want: W = V*I
W = 3.7V * 700 mAh = ~2.6 Watt Hours * 2 cells = about 5.2 watthours avalaible
W = 3.7V * 2200 mAh = ~8.1 Watt Hours
Now the 18650 is superior since it will supply 3.7V stored longer at load.
Of course, I recommend trying both configurations in conjunction with what you find to be your ideal vape including the resistance coil, wicking system and VV/VW. You have to factor in all those, since once you have your system set up, as soon as you hit the button and start vaping, all these above numbers change
