Not quite everything is relevant here. Prior to VV devices all one had was
Ohm's Law Calculator to help match equipment with atomisers, and this is how the chart above was created.
If the goal was to maintain current draw under 2A, (which was my goal in order not to stress batteries and prolonged their life cycles), you simply chose the resistance that would get you there. For example I prefer 7-8W, I can achieve that in many ways. The sweet spot is claimed to be between 6-12W with the median 9W. 9W would be the upper reaches for me. That being said some folks prefer reckless and do vape at 12W. The rice to pay, dependent on the batteries was battery and atty life cycles. Many still vape 6V with a std atty (2.2Ohm) which renders 16W unloaded and 13.4 loaded, still way to hot IMO. Now just move that slightly over to 2.5Ohm and you get 14.4W and 12.1 unloaded and loaded respectively. However there is a caveat. The drain on the battery is above 2A and unless you are using IMR batts, not a good thing. IMO that would be the minimal resistance an atty should have to be vaped @ 6V with an avg loaded voltage of 5.5V. A better choice would be a 3Ohm atty as all falls within specs with regards to durability and performance.
I use 3.5 for 6V and 2.5-3 Ohm for 5V because it puts me where I prefer to vape, 7-8 watts. I also use 5.2 at 7 volts, because in all honesty the 3.5s would pop at that voltage. 7V has since become less used in recent times.
I hope this clarifies where I was going with this. It is not complicated after using the chart for a while. Now with the VV devices you can fine tune for the liquid you are vaping, while keeping in mind the attys being used. This should prevent burning of the liquids, and short lived attys due to excessive voltages being applied to them.
Now that mumbo jumbo was in direct relation to voltages and resistance. You can further fine tune your vaping experience with the type of atty you use (all at std resistance):
- 801 = cooler vape, great flavour, great vapour, mild TH;
- 510 = warmer vape, good flavour, good vapour, great TH;
- 901 = warmer vape, great flavour, great vapour, good TH; and
- 306 = hot vape, best flavour, great vapour, great TH.
I hope this has been useful to some
ETA: My atties of choice is the 510, the 901, the 306 and the 801. The 2 Ohm 801 minis are at the top of the heap although not listed as such here. These of course are all std resistance with the exception of the 306. I do not like the LR 510, never did and never will. This has been my experience as a whole using attys from other sources. All bets are off with the IKV line
