dual coil vs single coil

[incognito1]

I'm trying to figure out the next step after using a 3.7v batt with a Boge LR cartomizer and I was thinking something related to a dual coil cartos. I was also thinking something related to 5v batts. Question is would it be a step up?

As I understand, wattage is a big component so comparing a 3.7v batt with a 1.7 ohm single coil carto with a 5v batt and a 3.1 ohm carto would produce the same 8.1 watts but would they differ in experience?

Hello Incognito,

I dont know about the dual coil but I bought a clearomizer from Liberty Flights (Electronic Cigarette - Cartomizers - Clearomizers).

I have about the same setup as yours but the LR cartos. Do you have any feedback or comparison about the Standard Res. Boge Cartos and LR Boge Cartos?

How much time did they last for you?

Incognito, hello and welcome to ECF! Is there anyone you know, or could hook up with in the Canada forums that has a variable voltage/wattage device you could try? I'm not using 5v so I might not be the best one to answer your question, but I'm sure someone who is familiar with 5v will chime in. Glad you are here.

I use my LR dual coils on my VV mod box at around +-3.7v. If you have a high enough mah battery, I think they say over 450mah, then you should try them out on it. If I vape them at higher voltages I get a burnt juice.

The 3.7V with a 1.7 ohm carto will use about 2.1 amps. The 5V with 3.1 ohm will use about 1.6 amps. Therefore, the LR carto will drain the battery faster than the 3.1.

@rule62, thats good to know but I'm more interested in the differences in experience.

Every different thing you put on a battery has a different experience. One experience is the warmth of the ohms and volts resulting watts. But everything else is different too - the higher ohm accessories may have thicker wire with more surface to vaporize. The brand or type of carto may be different and the stuffing may give easier/drag/wicking or harder, have coils in different places. But basically some say if you have equivalent brand and type of atomizer (for example) in different ohms on different volts but producing the same watts that the experience is not that much different. Others who are devoted to high voltage will say it's totally different and the only way to go etc etc. But people are fond/loyal of what they use - what works for them - so I think you would just have to try it and see how different you think it is.

i dont know how true this is but i was told by a few that dual coil is low res and single coil isnt?? and with h igher voltage is this at all correct or did i mix that up lol

Actually theres both LR and SR for single and double coil.

 

[dormouse]

I think there is only SR and HV for the actual coils of DC cartos, but the carto itself draws twice the power so the carto is listed by the combined ohms of the carto (i.e. the ohms of each coil divided by 2)

1.5 ohm dual coil is SR (two 3 ohm coils)
2.5 ohm dual coil is HV (two 5 ohm coils)


So a 1.5 ohm single coil carto is very hot on a 3.7v device
A 1.5 ohm dual coil carto is double quantity of standard resistance cooler vapor

A 2.5 ohm dual coil is for high voltage mods

And in either case - 1.5 ohms can sometimes damage mass-produced fat encased batteries like Ego (melt internal switch and cause it to short/overheat). Many only use ohms that low on decent size mods.

Many only use ohms that low on decent size mods.

Thats actually why I am not using LR cartos so far... I am afraid to deplete the battery life too fast.

Thanks for the info dormouse, really useful!

I have the same juice in a 2ohm boge on my 3.7v SB, and in a 3ohm boge on my 5v PT, and the taste, the TH and amount of vapor is quite different.
Everything you do will change the end result in some way. Even taking the carto that you are now using, and punching a couple of holes in the side, and putting in a carto tank will change the vaping experence.

I'm just trying to figure out what dual coils add to the experience over a single coil at the same ohms.

The two combos you listed vary in wattage quite a bit. I have to agree the two combos are different; Using my 2.7 ohm carto on a 3.7v batt vs a 5v passthrough makes a quite noticeable difference.

I've used 15 different model PV's from mini batteries to variable wattage models and just about every cartomizer and atty on the market with different resistences.

I can say categorically that there is a difference between vaping on a 5 volt or variable volt or variable wattage model and any 3.7 volt model. Regardless of the numbers, any good 5 volt model provides warmer vapor more consistently than any 3.7 volt model. And with models like the power regulated, variable wattage Darwin, you get warm vapor, great flexibility and the most consistent model I have every vaped. Every inhale is as good as the one right off the charger till the battery dies after 21 hours.

I also agree that different size/type attys/cartos vape differently due to how they are made, coil size, air flow, etc. I now mostly use dual coil cartos on the Darwin, although I also still use 801/BE112 attys/cartos also. The 801 is a good example of the differences mentioned. On a 3.7 volt PV, the 801's basically suck. But put them on a good 5 volt or variable volt model and they really come alive and hold up longer than most other attys.

If you want more consistency and warmer vapor, I would definitely suggest a good 5 volt model such as the GLV2 or even better, the variable wattage Darwin.
