Dual Coil = Twice the power requirements on a dna 30

[binks00]

I built my first dual coil last night. My single coil setup wouldn't fire below 12W and so i usually run between 15 and 17W. Does this mean i would need to run between 24-30W with a dual coil?

Would a parallel coil need twice the power to fire as well?

 

[albertoekim]

you are correct sir.

 

[binks00]

Thanks for the reply. I was just a little nervous pointing 30 watts at my face.

It all depends on what you want and how you build the coils. First, build them the same. Then check the resistance with an ohm meter before you fire it. The dna boards will not fire with a voltage lower than the battery so see what the minimum wattage you can use with an Ohm's law calculator.

Try various wattages and find the one you like best. Everyone vapes a little differently so you will probably be happiest at a wattage different than a buddy.

An Ohm's law calculator will also tell you how many amps your setup will draw. For a dna 30 I think the lowest resistance it will fire is .5 ohms and at 30 watts that is only 7.7 amps so with a a not worn out IMR battery it should not be a danger.

Evolv states that a battery no lower than 12amp continuous should be used with a DNA30. Just FYI.

This is what came in my Hcigar DNA 30. Does anyone know what this is and if it's any good?

 

[iClearoman]

That is a Sony vtc4 battery. It's a very good battery because it is a high drain 30 amp meaning it can handle up to 30 amps before it is at risk of venting (I.e. exploding). Plenty of power out of this battery it should handle most builds above .3 ohms. Just make sure you check your voltage and wattage with ohms law so you don't exceed 30 amps.

 

[binks00]

Great news, thanks!

you're right

if you feel your single coil needs all 30 watts to get the responsiveness you want, dual coil won't cut it with that same power output. you could try using a different gauge wire or just changing up your build

 

[Bigflyrodder]

Has nothing to do with the number of coils you are running, has to do with the final ohm level your build is. A dual coil, if each coil is the same, will cut your ohm level in half (i.e. a 1.0 ohm coil, if run in duals, will result in a .5 ohm build). Your mod and battery have no idea if your RDA is running single, dual, or even quad builds but rather knows what the ohm level is of the final build.

 

[KurrptSenate]

you're correct in regards to resistance, but it will also split those 30 watts between each coil if in dual coil mode

it's not like, if in single coil mode @ 30 watts, let's say it takes 3 seconds to heat your coil to be able to take the vape you desire, if ran in dual coil mode where both coils are equal, it doesn't mean both of the coils will respond the same way 1 coil did at the same wattage setting

 

[binks00]

My single coil runs between 12.5 and 17. Dual coil at 25+. Dual is too much for me.

Has anyone ever compared battery life for a 15W 4 second draw versus a 30W 2 second draw?

 

[KurrptSenate]

not specifically like that, no

too much as in too much heat or too much vapor?

 

[binks00]

Too much vapor. Its good if i draw for 2 seconds or less but that doesnt leave time to enjoy it. Ill probably go back to single next time i rebuild

 

[KurrptSenate]

yea you could

if a 2 second pull is too much, you could try letting go about 1-1.5 seconds and continue to pull after you've released the button. it takes time for the coils to heat up as well as to cool down.

you should see my single coil build on my OKR at 65 watts. that thing takes a good 4 seconds after I release the button to stop producing vapor

 

[binks00]

I'll give that a try. Maybe I'll order a second Magma so i can always have both setups.

Maybe someone will come out with an rda that allows you to toggle off one of the posts/coils.

 

[KurrptSenate]

they share a positive post so that might be a little difficult

maybe someday

as mentioned, it doesn't matter if you have dual coil, quad coil, heck even single coils. It all comes down to the OHMS. The lower the OHMS, the more watts would be needed. If you were using a non regulated mod, You would use lower OHMS to get more watts out of your battery (the more watts you want, the more Amps you need).

I see alot of people get a DNA 30, and put a .3 ohm mod on it and go, why isn't this thing blowing clouds?!? At .3 OHMs you are using more than 30 watts. In fact, you are lowering the potential watts, and even volts of that .3 ohm coil. It would perform much better on a non-regulated mod.


I have personally found, and this is my preference, for the DNA 30, a coil setup (single, dual, quad, it doesnt matter), .7 to 1.2 oms is the sweet spot. The lower the ohms the higher the watts you want. But, setting up a coil at 1.2 ohms, and using around 17 watts is awesome with my magma RDA for example.


If you want to use the full 30 watts, build your coil setup around .7 ohms. This is my experience using these new regulated 30 watt mods, everyone is different as for their preference, but OHMS law doesn't lie.

 

[binks00]

I target 1 ohm. 17 on the magma and 15 on the kayfun. No need for 30 unless its a dual which is fun but not a daily driver.

Exactly! People have a misconception that a DNA 30 device will push more power than anyone could ever want. If you use an ohms law calculator you will find that if you run the .3ohm build you mention above on a mech mod with a fresh battery at 4.2 volts it will draw 58.8 watts! That build running at the full 30 watts the device is capable of is actually running at 3 volts which is well below the point at which you should be swapping out any battery in a mech mod.

The devices are convenient and offer the ability to run subohm builds on a regulated device which is great but they are what they are.
