Bottom Coil or Dual Coil? Difference?

Status
Not open for further replies.
I am currently using bottom coil cartomizers for my Kr808d-1. The vendor that I ordered them from just sent an email that he will shortly be getting in some steel dual coil cartomizers. I am sure that answer is somewhere buried in the forums, but the sheer volumn of info here can be daunting to say the least. Can someone explain the difference to me? I was going to place an order, but perhaps I should hold off for a few days?[FONT="]

Take what I say with a grain of salt, as I am a newbie and not much of an electrical engineer. (Others who know more will chime in.) But I believe that the problem people are identifying is that the dual coils would generally have a lower resistance (ohm rating) which would overdrive your battery. My guess is that the orientation of the coils (horizontal vs. bottom) would not affect this much.

But let's hear from the more knowledgable folks.

You are right in the battery matter, but not in the orientation of the coils, the cartos with horizontal coil are much better then the regulars.

I think I actually understand that. Thanks.
I have already proved to myself that ecigs will work for me. Maybe it is time to upgrade to a system that is better. The big problem is figuring out what that is exactly.

Don't feel bad... that's always the problem for everyone! lol.

There's a lot of mods on the market. Lots of voltages and options.

You may wish to experiment with standard cartos a bit, or atomizers. However, if you want to be able to use DCs (dual coil cartos) you need to think about AMPs. DCs are like plugging two cartos/atties onto one battery. For example.... you could use a single 3.0 ohm atty and it would be a cool vape at 3.x volts (I use them at 5v). A 1.6 ohm DC is basically TWO 3.2 ohm coils side-by-side. Still cool but 2x the vape.

It takes twice the amps as a single coil version at the same coil-ohms. Many devices will be over-amped by this. Sometimes batteries cut out, or regulators over heat and quit. People have used them on the eGos and seem to like them. Of course, a charge won't last as long.

Do your research. If you want a voltage regulated mod, for example, check around and ask how it works with DCs.

Well, could be an issue. I think tho, that the DC's net out to 1.6 ohms. This is still a bit higher than the 1.5 ohm LR single coils. So if you'd use 1.5 ohm LRs, you could use 1.6 ohm DCs, except that they may be too cool to vape if you can't get the amps. So from the batteries perspective (not the user's vape quality) it's a little bit less taxing.
 
The big problem seems to be that the more I read, the less I know. I guess ecigs aren't much different than anything else. :)

I am not married to the idea of dual cartomizers. I just saw that they would soon be available from a supplier that I have used, but didn't know the difference.

Another large issue for me is that I would like to find one single supplier for juice and accessories. I would like to use a Canadian supplier to avoid any issues with customs. This is proving to be a problem.

...... Can someone explain the difference to me? ........

The duel coils are different because they have more surface area and produce more vapor at slightly lower temperatures. That's great for the folks that like good vapor production but not so much heat. In addition, they hold up well to higher voltages. At 5v, they produce hot thick vapor. Lots of folks like them at ~ 4.5 volts.

The bottom coil cartomizers have been getting good reviews. I'm thinking there's a possibility you'll prefer them to the duel coils anyway, unless you go to a higher voltage. Just my .02

I think they were trying to say that coil orientation has zero effect on battery life or it's ability to power a dual-coil.

Maybe I've got things wrong but it was my impression that bottom-coil and horizontal-coil are the same ... I mean the coil is horizontal in the things. What's the difference if that's not it?

The orientation of a coil has no effect on it's resistance. The length and thickness of the wire in the coil determines that. The only change between the horizontal and vertical is location in the carto and internal design. This changes how liquid gets to the coil nothing more. horizontal coils are near the middle of wicking material and horizontal are at the bottom near the connector.

Dual coils should really only be used with a very large battery like an 18650 or IMR high drain batteries, or lifepo's stacked for 6v. Smaller batteries including the ego don't have a suitable maximum discharge rate to use dual coil without added wear and possible failure. At the least you would significantly shorten the useable lifespan of your battery. The type of battery you use isn't suitable for an atty or carto lower then 2.5ohms. You may use anything you like at your own risk.
 
So let's see if I have this right...

The complete idiot's (pick me! pick me!) answer would be that dual coils should only be used with a large battery. It would work, but would kill a small battery rather quickly.

The difference between bottom and horizontal coils is basically only where it sits in the cartridge.

If I am looking for additional parts for the SmokeNV system that I currently have I should be considering Volt, Bloog or Halo batteries and cartomizers (unfortunately, I have only been able to find one source for Bloog in Canada and none for the others).

Have I got this all correct?

I will vouch for the bloog caroto's. I use them on my 808 as well as my higher voltage unit, and they perform amazingly!

You can buy the bloog stuff in Canada as well as quality juices from a few different places. You will pay a little more here, but it's nice to support the local vendors whenever possible.

Pm me if you'd like I'll hook you up with some vendors I love!
