Dual coil help

[txskimo]

I upgraded to a Lavatube V2 and was recommended the nautilus from a local store. This is the first VV device I've owned as well as the first dual coil tank so I'm trying to figure everything out. Looking at volt charts do I go by the resistance of the coil or do I double it because it's dual coil?

I kept reading about people running their nautilus above 4 volts but when I try it I just get a nasty burnt taste. The head it came with says 1.8ohm but reads 1.7 so according to the charts I've looked at I should set the volts to around 3-3.7 is that right?

With a new setup, Prime it, lower your voltage then up the voltage until you find your sweet spot.

You can double it. If you have a 1.8 ohm head in the Nautilus each coil is 3.6 ohms. So you could to 5 volts and you would get about 7 watts per coil. This should be doable if the wick can keep up.

I start my 1.6 and 1.8 ohm Nautilus heads at around 3.3v when they are new. After a week or so, I may go up a couple of tenths to as high as 3.7v. They are so efficient that you don't really need to crank them.

Dual coils are two coils wired in parallel. A 1.8 ohm dual coil is two 3.6 ohm coils wired together in parallel. Both are vaporizing juice so the vapor is heavier at lower voltages.

+1 with this. Burned taste might be from a dry coil and it has to be your sweet spot for the particular juice you are using. Some juices taste better for me at a cooler vape some at warmer vapes.

When you prime it do you drop liquid directly to the coils or just take a couple puffs without firing it? It seemed to fix itself after quite a bit of nasty burnt taste. Just trying to avoid this in the future and figure out what I did wrong.

When I first got it I did put in a different e liquid which tasted really bad and I figured since I've never used that liquid that was the problem. Ended up pouring it out and adding Nicoticket without doing anything else. Should I have cleaned the tank out first?

Yes, clean it when switching flavors and put a drop or two of liquid on the coil, and let it soak in, before firing it.

Actually the head that comes in the Nautilus is a 1.6 ohm head and Aspire includes a second head that is 1.8. Not sure why they do that.

In my short time vaping I keep reading about people running various devices over 4 volts and or upwards of 15+ watts or even much higher.

Personally I don't get it.
I also have a Nautilus and run it at around 3.4 to 3.6 (+/-) depending on the APV I'm using it on.

I also have just started using the Kayfun clones with coils right at 1.6 ohms and run them at that same 3.4 - 3.6 voltage. That is somewhere around 7 to 8 (+/-) watts. Anything higher with any and all of the tanks I have and it is not enjoyable. But then like everything else "Different Strokes for Different Folks".

I guess I'm a Wimp but I like vaping where I can talk after taking a vape.

On the Vamo V5's I have it set at that lower voltage and on the new Provari I just got yesterday I can go as high as 3.7. But after that it just doesn't taste right and is HOT to my throat. The Vamo's don't have a flat DC signal, the voltage varies from 6 volts to no volts giving an average of what you have it set to. Because of that I feel you need to have the voltage set lower than on a battery system that does supply a flat DC signal.
Not sure what your APV is delivering.

I'm doing this to stay away from cigarettes. It's not a contest, at least not to me. Do what makes you stay away from the cigs and what you enjoy.

Pulling while not firing works too..


And no, you do not double the voltage 'cause its a dual coil. You might be able to go higher than a single coil, but its no where near double. As said, try it where you would a single, or even lower, and go up 'till you find what works for you and your juice.

As I stated above if you are trying to run above 4 volts that is the reason you are getting a burnt taste. Take it back down to the 3's. The lower 3's and test.

I've hit my sweat spot. With 1.5 to 1.8 ohm coils I'm staying in the middle 3's. 3.3 to 3.7. Everything at this time is working and tasting good. That is if it is a juice I like.

As for the Nautilus. After getting the Kayfun Lite + clones I am actually liking the Nautilus more. The Kayfun has TO Much flavor with some of the juices I like. Overpowering with some.

The voltage is the same across each coil in a parallel circuit such as an ecig dual coil. Current draw varies according to resistance across that portion of the circuit. Dual coils give you more cross sectional area exposed to more juice at slightly lower wattage than a single equivalent coil. Efficiency of the design still plays into it. Not all dual coils are equal.
