Dual Coils On VV

[six]

I'm interested in knowing what sort of luck VV owners are having with the dual coils. There are at least a dozen or more dual coil threads and there is a post here and there scattered through them addressing the limitations of the VV units firing or being able to run the dual coils at higher voltages.

So, who is using dual coils on your VV? What VV do you have? How much voltage have you successfully been able to feed the dual coils without problems?

stownz uses his on his Provari, at higher than what i get... it may be the individual carto, but i can't get higher than 3.4 or.5 with my Vari before it codes out E2, and if i keep going it's an E1 which means popped dead carto...

The limitation on some VV units is the MAX current , If I remember the dual coils are 1.6 ohms or so right ? so @ 4 volts it is 2.5 amps of current draw and 10 watts ! 10 watts is HIGH for most people so much more than 10 watts is not very useful IMO ( some may like it but most do not ) , this is also true with protected batteries they have MAX current draw allowed , Un-protected batts like an Ego or ???( dont quote me on the Ego battery ) will not have this limitation and that is why they die fast , they are being operated beyond the specs for the battery.


I would like to see a 3 ohm dual coil personally .

I have read that the Pvari is limited to 2 amps as well ???? @ 3.4 volts that is 2.125 amps so it makes sense ,.

I agree with that, I also don't know how Stonz or anyone can enjoy these things at 6v but I haven't agreed on to many things with him anyways, to me these DC's have the best flavor around 3.4v-4.2v and the lower voltages having the better flavor and all around vape with these DC's for sure. I also get the E1/E2 on my provari in the higher 4's to 5v and I have to put them on a unit with no protection to use them any higher then 5v and when I did run them on a 5v Batt and especially at 6v they burn up, even if ya take short pokes they are not good like this in my personal opinion only of course, but just way to hot, I was wondering what would happen if you could make them in a quad coil but the Batts we use couldn't handle this Amperage

don't want to jack the thread, but along the lines.... someone uses a multi adapter set up, on another thread, to get a Go Go carto on his Provari....

I own 2 provari's i can run the dual coils up to 4.1 i do 3.9v most the time with them they work great!!!!!!!! Can't see why anyone would want to go higher.

 

[Liv2Ski]

my dual coils ohmed out at 1.3 and produced and error on the vari. They do work on the Darwin

 

[breaktru]

I run my 1.5 Dual Coil at 4.3v and 4.5v. on my V.V. Copper PTN08100w mod. Cranked it up to 5.0 and smoked like crazy. Back down to 4.5v and it runs great.

Ya i bet it went nuts to much.I have hit 4.2 with provari bit much .... works with well filled carto!

 

[mwa102464]

I can get my DC up to 4.7 when it is filled all the way up with liquid on my Provari, minute I go to 4.8 it error codes out on me. I used them at 5v with a 5v Batt, which comes off my charger hot at 5.4 so I did it there first, used it a bit and checked the batt every once in a while as it went down in voltage so I knew where I was at voltage wise, I then put it on my monkey Box with 2 aw LiFePO4's coming hot off my charger around 3.3 each so I was at 6.6 to the carto on a full charge and checked them every few pokes till it came down to 6v. Either way, bottom line is, 3.3-4.2 on the provari is there sweet spot and for me it is the lower end from 3.4-3.7 where I get the best performance, flavor, and all around vape with these DC's

I had one dual coil that was 1.4ohm, my Provari wouldn't have it. But if they are higher, like 1.5 to 1.7 (I've never had one higher than 1.7) the ProVari will do great with them at 3.7 or 3.8v. Anything higher is a no go.

In my opinion (using your 4v example), these should not be thought of as a single 10w device. They are two 5 watt devices in one package. The coils are separated my a couple of mm and don't rely on the same surface area to vaporize juice because they are separated. -- I like to think of them like light bulbs. What's brighter? Two 50 watt bulbs side by side or a 100 w bulb by itself? The 100w bulb is more efficient and therefore produces more lumens. I know this isn't a perfect analogy (or really even a very good one if we want to dig in to the technical aspects of lumen production vs visible light considering infrared being invisible... yadda yadda yadda). But at the end of the day, that's what we have. We have two heaters in one package each are 5 watts. We don't have a single 10 watt heater.

So, it sounds like the provari isn't for me. I'm running the dual coils around 5.0v now and I think I'd actually like to be closer to 5.4 or 5.5. Fresh off the charger 5v batts are perfect. 6.0v is just a bit too much. I've scorched juice a few times at 6.0.

So far, I now know the copper will get to 5.0v with the DCs. And the darwin was mentioned (any details on how far the darwin will go with the DCs?) Any others?

Just tried it for you. The DC I have on the Darwin is ohmed at 1.4 and dialed all the way up to 12.7watts the unit is pushing 4.3v at 3.0amps.

and what did you think of that Vape Liv ? To hot, ok, super vape, no dam good, ? which one ?

Actually it was not bad mwa. Not nearly as warm as I expected. Flavor was sort of washed out but vapor was definately there. I would give it a solid OK in my book. Nice to know you can go there if needed but not sure I will hang in that realm often. The Darwin has a 3.6v limit on the low end so it is pumping 9W with a 1.4ohm DC. That seems to be right about my sweet spot. A nice balance of flavor and vapor for me in that range. I am also a little concerned running these on the Darwin since I have seen batt life drop off quickly when hitting the DC's on this MOD. I have been pulling off the Provape-1 and the Reo grand with the DC's. The Darwin pretty much gets the Iken fusions or the V2's. They really are awesome on the Darwin, but then again they really are awesome on pretty much anything.

I was just pointing out the Ohms law aspect of it , really what you have is DOUBLE the surface area and the same power that IS split between 2 elements . so 5 watts each considering that they are the same length .

Where are you getting 5 volt batteries ?? I do not know of any >

I know of these (they're actually 4 X 1.2V stacked)

I like the dual-coil on a 5V PS passthru.
Lotsa snap, cracle and pop. Not hot at all, above average flavour, nice hit. Vapor is there while puffing but very little on exhale I find.
