If you want to vape at high voltage. Than you need a mod such a roughstack, Silver Bullter, Provari, REO, etc. That can go up to 6V. Then you would need either a 3 ohm or higher atty/carto to stand the heat.
A cheap way to check this out and other voltages would be a VV box mod from madvapes:
Variable Voltage Box Mod
This will let you find your desired sweet spot as well as use numerous combinations of atties/cartos (to match the voltage of course. for example, 2.5ohm & 5V, 1.5 & 3.7V). It'll save you a lot of money and the max voltage would be 7V (mine can actually go to 7.4V).
Also, this will be helpful as well to figure out which voltage your at:

Ohm's Law Calculator
Shoot for about 8 watts or less. Plug in any two values (like voltage, and ohms-resistance) and hit calc. That will let you select any combo of atty and PV.
I vape at 5 volts and use 3.0 ohm SR atties.... that's 8.33333 watts.

If you really want to try higher voltage washvap just gave you the best suggestion possible. Madvapes seems to actually have those suckers in stock right now too.
With a Variable Voltage mod like that one you will be able to use your old attys or cartos or turn it up to try higher resistance attys or cartos (3.0 -3.5Ω).
You won't find VV cheaper than that and once you're hooked you can start saving up for a more durable VV device.

Oh, that's cool. Looks like at 6 volts I should be using 4.5 ohm cartos instead of the 3 ohm I normally use. Well, there you have it. I just wish there was a little more variety in manufacturers, since the only 4.5 ohm carto I know of is SmokTech, but I guess I should be thankful those even exist in the first place.
The Madvapes vv box mod that washvap recommended gets good reviews. I have one coming today in the mail. It's $35 and you would need 2 protected 14500 batts and a charger, about $20 extra. It looks like a good way to enter the HV variable world cheaply. It uses a linear voltage regulator that goes from 0 to about 7 volts. The higher range is better for battery life, since when you turn it down, unused voltage is dissipated as heat by the regulator chip. A PWM mod costs more, but is better for battery life.
Still, the MV vv mod is a good deal since it lets you turn the voltage up and down in tiny increments to find the sweet spot for a given juice and atty.

Another vote for the Madvapes VV boxmod. I've built a few of these from the Rev 2 PCB kit, and they rock! It's wierd - I have a couple Darwins, but I keep finding myself using the Madvapes VV setup...
does it have to be that specific battery ? can i get a bigger and better battery ?? or am i limited to the 14500 only ??
For the Madvapes VV you'll need to stick with 14500 as it's built in a 3AA box and 14500 is the same size as AA, other sizes won't fit.
As for the brand of 14500, Trustfire and Ultrafire are very popular, I'd personally recommend AW but they cost a little more. If this is your first venture into VV and you go with that mod then just get the batteries and charger from Mavapes to save on shipping.

Tastes/preferences will vary. I'm currently running 13.33 Watts on a 2.7Ω atty @ 6 Volts, and like it for the juices I'm vaping currently.
I have other juices which taste better in the 9.23 Watt to 11.25 Watt region (3.9Ω to 3.2Ω, respectively) @ 6 Volts.
As others have said, experimenting to find your sweet spot--temp-wise--is worth it, and an inexpensive VV mod *would* save you some money on atties.
Then you start getting into draw, barrel length, wicking speed...it goes on and on.

I want to chime in here with more praise for the Madvapes VV Box.
I own a little stable of variable-voltage box mods. From Ken at BoxMods.net I have two Big Brother v1s, a Little Sister v1 (v1 means 1st generation that uses a linear regulator), and a Big Daddy Vari-Cool VV (Vari-Cool is a switching regulator, which is a more sophisticated and efficient voltage regulator board that wastes less energy and produces less heat, thus giving longer battery life). From Shan Burkholder at Vapecore.com I have a Big Splash VV with built-in voltmeter (which also has a linear regulator).
Last spring, I was considering a Darwin or ProVari, which are high-end VVs (with price tags to match), when Madvapes came out with their made-in-the-back-room VV Box. I thought, "Wow, 38 bucks shipped, can't beat that." So I bought one, thinking I would eventually get a Darwin or ProVari. Soon after, SmokTech's 1.5 ohm dual-coil cartomizers appeared on the scene, and lots of Darwin and ProVari owners discovered that these fantastic new dual coil cartos either didn't perform up to snuff or wouldn't fire at all on their devices, due to the amp cut-off limit built into their high-tech switching regulators. I encountered the same problem with my Big Daddy.
Meanwhile, my supposedly less sophisticated linear regulator VVs all worked like a charm with dual coils. Go figure.
I also discovered that my Madvapes VV Box was an incredible vaping machine. It hit like a freight train and out-performed every other PV I owned (I had more than 20 at the time), including my other VV mods. So I bought a second one, and it was every bit as good as the first. Great throat hit, massive vapor, and intense flavor.
Now I own seven Madvapes VV boxes, and I don't even want a ProVari, Darwin, Buzz Pro, or any other VV.
Some folks don't like the Madvapes VVs because the cases are just 3AA plastic boxes, which they consider either unaesthetic or flimsy, but I love them! I've never encountered any problem with them, nor have any of them broken after being dropped. They're actually quite sturdy and reliable.
Then too, certain modders have a bias against linear regulators, saying that the cases get hot and battery life is cruddy. I've never had either of those problems. Not once. No noticeable heat, and I get days of vaping from a pair of rechargeable 14500s. Then just swap 'em out for another pair of fresh 14500s and slap 'em the dead ones on the charger for about three hours. A good charger and a slew of Trustfire 14500 back-up batteries (either the blue- or the flame-jacketed 3.7V 900mAh work great) don't cost much from DealExtreme, and then you're set.
Yes, a voltmeter is very handy to have. Not absolutely necessary, but---trust me---you're gonna want one. For $15, Madvapes sells an assembled 3-digit LED meter with male-in and female-out 510 connectors (meaning you can read the voltage either with no load or under load). Definitely worth buying to accurately set voltage.
I now own more than 40 PVs, but nothing can hold a candle to my Madvapes VV Boxes. They work perfectly with all atties and cartos---every style and resistance. They're lightweight and fit the hand nicely (no matter how big or small your hand is). And they perform beautifully. For about $75 total (which gets you the VV box and voltmeter from Madvapes, plus a FancyFire multi-battery all-in-one charger with three sets of Trustfire 14500 batteries from DealExtreme), you can't beat it with a stick. And even if you don't like it for some reason, put everything up for sale on the Classifieds for 60 bucks. It'll get snapped up fast, and you'll be out only $15.
