I have a 2.0 Ohm dual-coil clearomizer/atomizer, and a variable Ego Twist II, with a variable voltage of between 3.3v and 4.8v. How would I factor in having dual coils, I've calculated at 4.0v with a 2.0 Ohm coil I would hit the 8-watt sweet spot. Do I need more voltage because I'm using dual coils clearomizer/atomizer? The reason I ask is so I can decide on a different clearomizer/atomizer with a different Ohm coil and stay in the safety zone and get the best results. Any help would be appreciated.
