Low Voltage vs High Voltage Vaping. (harshness of the hit)

[**Jay**]

Now I know this is mostly personal preference, however with an ego mega v2 and a Smokteck 1.5 dual coil (I've been told that makes 3 ohm total resistance) I've been getting really hard hits and barely any vapor at all. I've ran from 3.8-6 volts on this thing and I can't find that perfect place. I would like to add that it is super easy to draw from, kinda like A straw. Is there a possibility that the carto was primed improperly?
Appreciate it!

That's not what you were told! (if I'm thinking of the proper post).

You were told that a 1.5 dual coil is two 3.0 ohm coils. Total resistance = 1.5 ohms.

If it's burning turn it down. Yes, very possible it wasn't primed properly. Also, too thick of juice = burning too. Thin it.

Also what does "really hard hits" mean if it's airy and no vapor?

What you have there is two 3.0 ohm coils. The resistance is 1.5 ohm. Harsh hits with hardly any vapor is due to semi dry wicks. Also it can give the same results due to flooding. I usually ran 1.5 ohm duals at 4.2 volts.

What do you guys suggest to fix this issue. And sorry for the confusion on the last thread AttyPops. IMO the juice is not thick. So it must be the wick

How long was it used? Or did you have this issue from the get go ?

Work your way up from 3.5 volts and make sure you are getting juice to the wick. You probably won't need to go above 4.2v. Prime again if needed.

I've had it a day now and yes it has been from the beggining

Try what Exhaler mentioned.
If that doesn't work replace the heads. Good luck man.

From what I've read... dual coils on any eGo might be a no go... they have limited current. Not sure what the limit is on that v2 (I had one, but it died a week after I got it), but it might be too low.

For dcs, you might need an APV that has a battery that can push up to 4 amps and over 10 watts... something eGos can't do. Don't quote me though.

Carto tanks have carto problems and tank problems combined. lol.

So...if it wasn't primed properly you MAY have burned the carto. Add to that the size of the holes in the carto and the thickness of the juice. Also some cartos just wick better than others.

So a burnt wick = gunk and gunk = bad juice flow too. Maybe set that one aside, prime a new one with a syringe or something, let it soak in, and then put it in the tank with juice. Make sure it's 100% saturated. Start at the lower voltage Exhaler suggested (4.2) and see how it works.

1.5 ohms at 4.2 volts is 11.76 total watts divided between 2 coils = 5.88 watts per coil. Usually considered very cool if even vapable. Kinda depends on preference. Many DCC users use them for the cool vapes though.

Also, some devices are amp limited and won't put out the power needed so the effective voltage suffers. It's not blinking though so that doesn't sound like the problem.

It's tricky! If you can put a 1.5 ohms single coil on them, you can put a 1.5 ohm dual coil on them...HOWEVER...the watts for the dual coil are divided among the two coils making them ineffective at heating. So the power is the same, but the effect (the result) is WAY different.

So to compensate you turn up the voltage to power the two coils. It may or may not object at that point. So you're right if you account for having to turn up the voltage.

P.S.
Sorry...I quoted you!

alright, I took it all apart. I re primed the cartomizer again and I'm getting full vape at five volts... Just bad priming I guess. thanks everybody for your helP

 

[LeoRex]

Voltage will be what you see regardless of how many coils... it's what is going into those coils that matters...

Most people like vapes in the 7 to 8w range. On a dual coil, that is 14 to 16 total watts, something even a lot of APVs have trouble doing without stacking batteries. No way that ego can drive that.

Yep.

Buuuuut....what mess people up is also the ohm's charts. They use 1.5 ohms and try to look up the volts and they get 3.2 or 3.4. lol.

So you're correct from a watts perspective but they either have to remember to halve the watts to account for two coils or double the ohms 1st then look it up.

It messes newbies up almost every single time. I wish they came with instructions or just simply went away. But that's me. Lots of people love em.

Best to remember to double the ohms for dual coil stuff then look it up.

Of course, like you said, none of that means the device can power it.

 

[**Jay**]

Yes you are right. But at 4.5v I am getting a great cape. Better than 6v. It doesn't make sense but I am telling the truth. My main problem was the carto wasn't primed all the way. If I get a chance I post a youtube vid of the setup and the vape I am getting.

 

[AttyPops]

lol. DON'T go to six volts! I didn't say that! You'd double the 1.5 ohms (to 3.0 ohms) and use 3.0 ohms in the chart. And come out at like 4.2 - 4.8 volts.

The voltage is squared in the watts calculation. So just because you double the ohms, doesn't mean you'd double the volts.

 

[LeoRex]

Yeah... a chart for dual coils would be nice, along with a current load. After all, batteries are rated in miliamp-hours.

 

[Exhaler]

Glad you got things rolling.
Until I got my first Vamo I ran a dual coil dripper on a V2 Mega and it was able to handle it quite well. I used 32 and 34 wire and tried to stay above 1.4 ohms total on my multi meter. I did not try to over power the V2 at all but I don't like hot vape anyway. Never have used the V2 above 4.2v.

I usually run about a .5 ohm coil on everything I have, don't really calculate watts or anything anymore, I just know how I like my vape. I know on a fresh battery using ohms law that would put it around something like 30 watts I think, but I really doubt that is actually the case after you figure in everything else.

 

[AttyPops]

What does that have to do with how many volts you need to power a stock 1.5 ohm dual coil and get it working?
