Cartomizers and voltage

[romkush]

Hello ECF,
I'm using the eGo Twist and vaping on 3.8 volts with a 1.8 Vivi nova and I've been told I should use a higher resistance carto with higher voltage to achieve better results and save battery power. So if I witch to 2.4ohm or 2.8 ohm how much voltage should I put my twist on?

The idea is to dial it up and down until you like it.

Start low and work up.

EDIT: Also ... you can use V*V / R to get watts. Most like 6-9 watts (per reading around here).

Using the calculator, I should get about the same wattage (8 watts) with:
1. 3.8V with a 1.8ohm carto
2. 4.4V with a 2.4ohm carto
3. 4.8V with a 2.8ohm carto

Options 1 and 2 work fine but when using a 2.8ohm carto and 4.8V I get almost no vape.
Why?

Bad carto? Or at least a less performing carto.

Could be a bad carto, it came along with Vivi nova set.

I have that set-up...

1) You can use whichever you want or all three
2) The rough way its supposed to go which it does for some people (and me) not others is
1.8o for the ego designed for 3.3v or so
2.4 for the 3.7 bats around 3.7
2.8 for vv devices like 4v++
3) This is where my juice sits but at 3.3v its a cool vape
3.8 is warm
4.2+ is warm/hot
4) So if you use a different head it will really impact the flavor and heat -- I hate hot juice so I use the 2.4
5) It really depends on your juice--some people vape high volts on it all
6) The reality is the Nova is a low volt device really. If you switch head for power it will impact the flavor of your vape. You should try all 3 heads it came with to see what I'm talking about...

I did try them all but why my 2.8ohm head produces almost no vapor?

Bad carto. It happens. Just search the forums for ppl complaining about boge cartos.

Yeah. Hard to tell unless you have a multi-meter. Then... it may help to test it (ohms).
