Dual coil (mega)cartomizers, clearomizers, tank-cartomizers

[elfstone]

I promise I tried to figure this out for myself, but I keep finding contradictory info on this forum and elsewhere. The problem is with these 1.5-1.7 dual coil devices and whether they are safe and reasonable to use on which batteries.

Here are the pieces of info I keep finding: that <2.0 ohm cartos damage regular batteries because they drain too much current (you can say it in various ways - higher amperage / higher wattage / higher power output / higher drain than what the battery can handle). However, on supplier sites I find statements such as a "1.5 dual coil mega carto is designed for eGo" (which is not a high drain battery) or that "We recommend 1.5ohm for Ego batteries or 3.0V-4.2V batteries and 2.5ohm for 5V or higher". Is there something I'm missing? Is there a difference in the dual-coil thing?

Bottom line, should I use a dual-coil mega / XL carto on 3.7V / 900-1100 mAh non high drain battery?

On a 900-1100mAh bat ... no problem.
on a 180-220mAh bat ... problem.

You will find a lot of the REO people that are really down on Li ion bats, but that is a specific use problem related to using LR atties on their PV.
So which 14500 PV are you using?
As an example of different points of view, I wouldn't even think of using a non protected bat in a PV that doesn't have built in protection ckts.

I'm not using anything I'm looking into a kGo/Riva 1100 mAh... Hope it makes sense.

Both have protection ckts in their switch. The only thing you will find is that the DCC drains the bat pretty fast.
A DCC wouldn't be my choice of cartos on them, but that's just me.

Slim ecigs should only use standard resistance attys/cartos. Low resistance and dual coil attys and cartos are only for bigger battery PVs. Egos and 3.7V PVs are considered bigger battery PVs and can handle them.
For an eGo though, I wouldn't use anything lower than 2.0ohm. EGos are mosfet driven PVs and 1.5ohm and 1.7ohm cartos put alot of stress on the mosfet and can fry it, killing your PV. Some eGo users use below 2.0ohm and have never had a problem, but there's also alot of people that have fried and eGo using them. 1.5ohms are the biggest culprit to a fried eGo and they put the most stress on the mosfet. 1.7ohms stress the mosfet too, but not as much. I know quite a te people that use the Ressurectors which are 1.7ohm on an eGo without problems, but at the same time one of my best friends fried his eGo about 2 weeks ago with a Ressurector. That's why I recommend not using anything below 2.0ohm, more or less just to be safe.
3.7V PVs handle the lower ohms better than a 3.3-3.4V eGo, and that's one reason I prefer them over the eGo, like an Epower, kGo, etc. all I use is 1.7ohm Ressurectors on my Epower and have never had the slightest problem, but have also used 1.5ohm cartos on it too with no prOblems. I don't know what PV you use, but if it's a 3.7V PV you should be fine.

I don't know why some vendors say stuff like that, and I think stuff like that has a lot to do with why some new users unknowingly fry their eGos and wonder why. There are also quite a few vendors that say its not recommend to use below 2.0ohm on an eGo, or I've also seen some say 1.5ohm cartos and dual coils are not recommended for eGos or other mosfet driven PVs.

You can use dual coils, but personally I find they really arnt that great on lower voltages. They are alittle better on 3.7V PVs compared to an eGo, but their still nothing special. I find that dual coils only really shine when used in the 4-5V range. Personally I think a good single coil carto is just as good if not better than a dual coil on my 3.7V Epower. I've tried quite a few dual coils and the Ressurectors which are single coil produce just as much vapor. A 1.5ohm dual coil is actually 2 3.0ohm coils running parallel. Personally I think a 3.7V PV and especially an eGo just doesn't put out enough power to run them that well. Since its 2 3.0ohm coils it gives a cooler vape and personally I prefer the warmer vape and more TH that a good single coil provides. On a PV that puts out 4-5V though, dual coils work great bc the PV puts out enough power for them to actually pack a punch.

 

[elfstone]

I see. But it doesn't shorten the lifespan of the batt?

It does to me. I am a Noob, too, and I would like to know the inner workings of the dual coil when it says 1.5 and 1.7.
On dual-coils in general; I thought that it meant 2 coils rated at 1.5 and 1.7 respectively; meaning a total of 3 and 3.4 total resistance, but, since it was split by 2 coils, it would not feel like it had that much resistance, because 2 coils were utilized to help heat the liquid.
I was wrong, but never understood it just the same.
I wish I knew what it means in a complete Noob type of way.

That said, a kGo will indeed work with either one, as it's rated at a slightly higher voltage than the rest of the eGo type of clones. I don't have the Riva, but from what I understand, they are just like the kGo as voltage is concerned- just a tad higher than the regular eGo's and clones.

 

[mynameisrob]

The kGo is a good PV and I think youd like it. The Epower is similar and I almost got a kGo, but went with the Epower bc I really like that it uses non-proprietary batteries like a mod does and the non-proprietary batteries are alot cheaper, plus everything is replaceable on the Epower so it's much cheaper to maintain.
The kGo is a solid PV though and gives a great vape and has long battery life. Personally I don't like the dual coils on the Epower and kGo, but you might like them. I would also try the 1.7ohm Ressurector cartos bc they work absolutely awesome on the kGo and EPower.
Keep in mind If you do try dual coils, like tj said, they do drain your batteries alot faster and they also eat thru juice alot faster than a single coil too

It's the other way around.
A 1.5ohm dual coil has two 3ohm resisters for a total resistance of 1.5ohms.
Where it differs from a 3ohm carto is the juice is exposed to twice the heating surface. So twice the amount of juice is vaporized.

I see. But it doesn't shorten the lifespan of the batt?

You will be charging the bat more often which in essence shortens the lifespan of the bat. (so it lasts for 5 months instead of 6)

Thank you- I had it backwards. This makes sense to me now.

This is what I learned through using a dual-coil (1.7) on my kGo. I actually like the single coil 2.0's better. I wasn't having battery issues, I just liked the vape better.

I found I def like single coils more too. I tried dual coils bc I figured theyd be better but realized they really arnt at the lower voltages like 3.7V PVs or 3.3-3.4V eGos. Honestly I think alot of new vapers that have eGos etc use them bc they just assume they are better. Personally I like a warmer vape and the added TH that the warmer vape provides and the dual coils just don't give that unless the voltage is higher. If you try a 1.5 ohm single coil and a 1.5ohm dual coil, you'll notice the difference. Even though they are the same resistance, the dual coils vapor is alot cooler bc it's really 2 3.0ohm coils and 3.0ohm generally provide a pretty cool vape.
Everyone's different and you might find you like dual coils, but I find the downside of draining your battery faster and going thru alot more juice is not worth having 2 coils instead of one.

 

[elfstone]

This makes perfect sense!

Now please let me remind you that I am a newb: I'd like to try one of those tank things! Everywhere I look it seems (most of them?) come with dual coils or with >2.5 ohm cartos. Is there a reason I shouldn't just stick a 2.0 Boge in a tank?

 

[mynameisrob]

You def can just stick the carto you want in as long as its the right siZe tank.

Personally I use the Smoktech tank on my Epower. It's cheap and works great. It even comes with a carto in it and a drip tip! The carto is a 1.5 ohm dual coil though which I'm not a fan of so I didn't use it. Instead I put a Ressurector carto in it and I absolutely love it now! Crystal Clear Vaping sells prepunched Ressurectors for a great price and they have the metal base on them to be used in the Smoktech tanks. You don't have to use a carto with the metal base, and toy can just punch your own and use whatever carto You like, but I actually like the metal base bc that stops the tank from being able to slide down. You can get the tank and prepunched cartos from CCV to make a great setup for a kGo or similar 3.7V PV like Riva or Epower. I also recommend getting a Big-belly drip tip to go on the tank. They look super nice and they fit snugly so they don't wiggle around at all. The reason I like them for the tanks is bc they are slightly wider than the carto so they stop the tank from sliding up. So with that drip tip and a carto with the metal base, the tank can't slide up or down and possibly leak bc of it. You can also get the same prepunched cartos, tank, and drip tip from Hoosier ecig supply, but I like CCV bc they have free shipping.
Smoktech makes a 3.5ml tank and a 6.5ml tank. Personally I use the 3.5ml tank on my Epower. I find that the bigger tanks look funny on Epower, kGo, riva size PVs and they make them really topheavy. The 3.5ml tank doesn't look awkward and is about the same size diameter as the battery tube so it looks good and isnt topheavy. Even though the 3.5ml tank is smaller it still holds alot of juice. I fill it in the morning and easily am good all day and don't have to worry about refilling it till the next morning.
With the smoktech tank, you couldn't use a Boge carto though bc they are too short. The smoktech tanks need XL cartos like the Ressurectors. If you do like the boges, Hoosier does sell the XL boges that are the right size to fit in the tanks.

There are also a bunch of other nice tanks that will work with the shorter Boges like the Chibi tank from parkes vaping or the j-tank from electronicstix

Thank you so much, sir. Now I'm watching pbusardo going on his fishing trip with the J-tank

I think some of the newer eGo batteries are designed for LR (low resistance)..probably they just went a little more heavy duty on the electronics to handle the load. I would only suggest a eGo that was listed a LR to use below 2ohms. I've been seeing some SmokTech at MadVapes that have LR right on them.

Yeah there is a new eGo battery out that is designed for LR attys/cartos.

I havent used one so I can't say anything about it, but it seems to be getting alot of really bad reviews. Most of them about it breaking and/or stops working.
It wouldn't be a bad battery to get for eGo users that prefer below 2.0ohms, but what good is a LR battery if it stops working.
I wasn't planning on getting on anyway, bc I prefer the 3.7V PVs, but if I was thinking of getting one, I would be very hesitant after reading all those really bad reviews, and they were from numerous vendors carrying it, not just one

Yeah I have seen the bad reviews..I try to tell people to read reviews on things. I'm sure it will be sorted out with the LR eGo's because I'm sure the vendors get sick of replacing them as I'm sure the manufacture has to cover the broken ones too..they will either drop them or the manufacture will fix the issue. With electronics a 3% failure rate is considered acceptable...

Hiya Guys & Gals

Looking for some guidance here as I'm still confused.

My current Sweet Spot is as follows

SmokeTech Dual Coil 1.5 ohm carto / tank on an eGo C Twist at 4.6 Volts (my own DIY 70/30 PG/VG Juice).

This combo gives me a good warm vape with tons of flavour and decent amount of vapor and nice throat hit - yes I do go through juice fast and have to recharge the batteries fairly frequently but I like the vape so will deal with the downside.

My question is this:

Just ordered a Provari V2 - What carts should I be using to get a similar or better experience - so much contradictory info on the web. Can I still use my dual coil 1.5 ohm carts or do I need to use a higher resistance cart?

Any guidance would be most appreciated.

Cheers.
