6 or 7.4 Volt Vaping

[echofinder]

Good morning y'all.

I am considering the purchase of a Roughstack v2; I like the idea that I can alternate between 3.7, 6, and 7.4 volt vaping as need dictates, but I have never worked closely with anything above the standard eGo.

So, my question is: what kinds of carto work best with high-voltage vaping of this nature? Which cartos will not work with higher voltage? Thanks in advance for any help.

Depending on your tastes, you will want to have about the same, or a little more wattage. So if you like 1.7 ohms at 3.7 volts (3.7 x 3.7/1.7 = 8.05 watts) youll need at least a 4 ohm carto @ 6 volts. witch is 9 watts. A 3 ohm carto would be 12 watts at 6 volts. Now of course the battery voltage when you push the button will be a little less. With 6 volts, its much easier to get lots of power(watts) and tons of vapor. But if you over do it, you can get a burnt taste or even burn the carto out. I use this calculator all the time.

Don't forget 5v with the NiMH battery available at MadVapes as well.

As for cartos...

The lowest resistance single coil carto I would use @ 6v is 3 ohm which gives 12 watts of power. For dual coils you can use lower resistance because it's really just two higher resistance coils wired in parallel. So for a 2.5 ohm dual coil there are two 5 ohm coils. @6v each coil produces 7.2 watts of heat for a total of 14.4.

Personally, I tend to stay in 8-10 watts range, but everyone is different.

Ohm's law is your friend.

Volts divided by resistance equals current (V/R = I)
Volts multiplied by current equals watts (V*I = W)

With a little math it's pretty easy to figure out what resistance atty or carto to use with whatever voltage you are vaping.

...a really rough rule of thumb...subtract around 2 from voltage and that is the carto you want...a 4ohm for 6v and a 5 for 7.4...you can go .5ohms lower but that is about as low as you will wanna go...subtract 3-3.5 for dual coils...if you use Ohm's Law Calculator (enter volts and resistance, hit calculate) and try to stay in the 8-10watt range, you should be good...remember to split wattage answer for dual coils..............

p.s. if you use the single 5v batt setup, you will need a special charger just for it...the charger will not work for LiIon batts and vice-versa.............mj

Wow! I do that on my VV. I pop on a 2.9, and adjust to 4.9 to start! Iv found with several different cartos, the +~2 volt rule works out well when you don't have a calculator handy! So yes, I totally agree for a single coil, ohms + 2 volts!

I prefer variable voltage over the mechanics of various batteries and mod body parts coupled with imprecise matching of voltages to different cartos. ...lots of juggling with the proposed system.

These at 7.4, even tried at 6 and not too bad:

3 ohm at 6v is fantastic. A great vape if certain things are kept in mind. With that wattage you want to hit it hard and fast, like an analog but a deeper drag. Also, it will ruin cartos pretty quick and things MUST be kept wet, otherwise you'll melt your tonsils
