Would it make sense to have a supply of tank carto's of differing resistance when using a DAV?
As I understand it, the only dual coil cartomizers are 1.5ohm (2, 3.0ohm coils wired in parallel. I assume this is done to increase wattage from lower resistance, hence more heat...but I digress).
I'm thinking I can achieve the same "heat" by "dialing-a-volt" so to speak.
If I set the DAV to 4.7v with a 3.0ohm carto, that will output 7.36w. If I set the DAV to 3.3v using a 1.5ohm carto, that will output 7.26w...close enough to the same "heat" I would think.
So if I can get the same (or very similar) power output using a single carto type, is there a reason I should have something other than a 1.5ohm DC carto?
I'll leave the tech stuff to other more informed members (who I am sure will weigh in soon)...
what I can speak to is what I do. I keep a healthy supply of tank cartos in both DC and SC, and in 1.5 and 2.0 ohm.
I love to experiment with each flavor on my DAVs using the whole range of voltages, and using each different carto. I keep a tasting journal, just like I did when I smoked cigars. (I also do this for wines and spirits).
So, in answer to your question: Yes, it would make sense to have a supply of tank carto's of differing resistance when using a DAV...and I do!
Thanks for the feedback Darin. Your opinion is valuable :)
I would still like to get some feedback to my earlier techno-babble...just for my own understanding.
KY_Rob sir, here's a link to help you out-
Running a DC and SC at the same voltage/wattage doesn't always mean the same results. Depends on the juice, and what voltage. Will use new menthol wow as an example. With a single coil 3.0ohm carto once you hit around 12.7w/6.2v the menthol completely takes over the juice killing the complexities of it, yet with a 1.5ohm DC carto it isn't until around 15.6w/4.9v that the menthol overcomes every other aspect of new menthol wow. This is one of the major reasons why VW never worked out as the set and forget it way of vaping it was billed to be.

While matching voltage is one way to get 6 of one and a half dozen of another it unfortunately is not that simple when comparing a Single to a Dual Coil.
While the voltages maybe close to the same, the amperage or rate at which the battery is draining power is not. 1.5 DCC do well with regulated and unregulated devices (3.7v - 4.2v) however they weren't really intended for VV devices.
Vaping is always a 2 part equation, in the old days before VV devices the only way to change the wattage on standard regulated and unregulated devices was to change the ohms of the atomizer. However, there is no longer a need for playing with atomizer ohms now that you can change the 2nd part of the equation...the voltage.
4.7v with a 3.0 ohm atomizer will indeed give 7.36w, but it does it while only draining the battery at a rate of 1.56 amps. While using a 1.5 DCC at 3.3v does give you 7.26w, it does while draining the battery at 2.2 amps or at a drain rate roughly around 33% faster.
I have never understood why there are no KR808 2.5 Ohm Single Coil Tank Cartomizers, 2.0 is still a little low and 3.0 is still a little high for VV devices. Is it that much to ask, would you really have to tear down the whole factory just to make a 2.5 ohm Single Coil Tank Cartomizer?
If I were a Vapor4Life VV owner I would be demanding that they carry a 2.5 ohm Single Tank Carto. You deserve your porridge to be just right...not too hot and not too cold. Your current choices leave much to be desired and little room for getting the best of your VV device. Dual coils are best used with 3.7v regulated and unregulated devices, not VV devices.
If I offered you 2 identical cars to travel across the country in, the only difference was one could achieve 24 mpg with a top speed of 100 mph and the other could achieve 16 mpg with a top speed of 55 mph which would you choose?
Very thorough explanation Mr. Snowdragon, and it is very much appreciated! The available working current of my DAV's is what I was after...this explains why I haven't noticed much different between the 3.3v & the 4.8 settings, other than slightly larger clouds...

My next act will be to order some 2.0 & 3.0 SC carto's, and see what happens :)
Thanks again for the assist!
I have to study this info MUCH more. I fear I'm draining batteries faster than necessary. Thank you KY_Rob and Snowdragon.
No need for thanking me TD :)
Snowdragon gets all the credit for this one! :D
After sitting down and doing some math (now that I know the max current output), a 2.0ohm carto will get me the most "heat" at 11.52w (within my 2.6amp limit), and provide me with a broader range of power usage. Now if I find a finicky juice that likes to slow cook, I can put in a 3.0ohm carto and dial that baby back to 3.3v, and let it heat at 3.63w.
...ohhhh my I can't wait for those carto's to show up!! I just got some Almond Coconut, and the lower I go, the better it tastes...but I can't get below 7.26w yet ;)
What is a KR battery?

I don't understand regulated versus unregulated devices. Which Is my Vapor4Life DAV?
Volts versus watts produce varying amperage drain that depends on the choice of dual or single coil cartos and is affected by choice of resistance. Higher amperage equals more heat equals more vapor, correct?
i understand the car mileage and speed metaphor, but I'm too ignorant to sort out what is optimum for battery and carto. So, lay it out for me, please.
I want (right now, anyway) good flavor, lots of vapor, and my battery to last a long time. I know I'll always want good flavor, but I suspect vapor volume may start to diminish as a priority. That leaves battery life. Maybe I'm making this too hard?
Just to be clear, I am only trying to understand this stuff so I make wise buying choices and do NOTHING to jeopardize my status as a former "stinky" user. No disrespect intended.
Thank you Snow as alway's for trying to uncomplicate for us (speaking for me only:)))))))))
