Cartomizers/Batteries

[TexasRain104]

I have spent the past couple of days looking for an answer but could not find one. My question: Which battery goes well with which cartomizer for the vapor/th/flavor? I know its all subjective, just trying to get a basis for the next order.

Ex: mini needs cool cart or premium?

XL needs cool cart or premium?

PT needs cool cart or premium?

I dont have a mod because im assuming that the mini, XL, and PT covers the 3.7 and 5 volt range. Is this assumption wrong?

@3.7v needs cool cart or premium?

@5v needs cool cart or premium?

Sorry for the noob questions, just having some confusion...

 

[LastOutlaw]

I don't think it matters one bit which carto goes on which battery. The new coolcarts are just bigger and burn a bit cooler to my understanding. V4L is supposedly moving to the premium carts and I guess coolcarts for all batteries they supply.
Feel free to order what ever size batteries you want...they work with all cartos.

 

[TexasRain104]

Yea, I know they all work, im wondering if its like high resistance/low resistance...

 

[Adrenalynn]

"regular cartomizers" are higher resistance. "premium" and "cool" are lower resistance. Neither of which have any business being run on 5v, imho. The regular cartomizers, which are getting scarce, are a better choice at 5v and above.

Hey Adrenalynn, question for you,
You say the cool carts are lower resistance (as are premiums) but are they the same as the premiums ... Im getting so confused with all the choices anymore! if they are lower resistance then what makes them "run a little cooler" and if they run cooler do they produce the same vapor as the premiums ....

Sorry that was a few questions wasn't it ..... I'm just soooo confused !!

Sorry to the OP for the OT

I don't consider this a noob question, Tex...I've been around these parts for some time and I was considering posting the same question.

High resistance, low resistance, Ohms, Voltmeters...it's all a little daunting to the layperson. I never thought I'd need to know all of this to vape.

Alynn's post helped. If I'm understanding correctly, she's saying HV should use HR (old style cartos) and vice versa (use premium and cools at LV) but if that is the case; what cartos will we use at 5v+ vaping with the old style cartos being phased out?

 

[Adrenalynn]

Yes, CM - and there-in lies the rub.

Mech - I'm not so sure that "cool" means "is different thermodynamically" rather than "Wow!" "That's Cool!"

Marketing wins over technology every time, ya know? I'll drill some holes in this one I have here, slap a thermistor or three in there and confirm that the profile is typical before I absolutely confirm or deny.

Leaford posted the following when he first introduced the cool carts:
NEW!! CoolCarts empty cartomizers! We have had two styles of premium cartos for a while now, but only one type came in blanks; now they both do!

To distinguish the two, we are calling the new ones CoolCarts Blanks!

These are the same cartomizers as our old hard caps, but with soft caps now, and are also available prefilled in many flavors, like Pink Lemonade, Green Tea, and Margarita.

They are slightly longer than the Premium Blanks, come with softcaps, and have the rubber condoms with the nipples inside. They have a higher resistance than our Premium Blanks, resulting in more puffs per fill, and many people say they have a higher fill capacity.

These are the cartomizers I worked with the manufacturer to improve, and which have already been carried by some of our competitors at a higher price.

Personally, I've used the higher resistance variety at 5v without a problem. But, I agree that the lower resistance Premium cartos are best at 3.7 v

 

[TexasRain104]

Now that the cartomizers have been somewhat grouped in my head, the V4L batteries (KR808) are 3.7v? and their PT is 5v?....

 

[TexasRain104]

and if thats true, why does the friend I know have a "quoted" 3.7v device that produces less vapor/TH/flavor on the same liquid as my mini/XL?

 

[GrannyM]

AFAIK, that is correct.

Not sure about your other ?. Is your friend using a KR808 battery?

 

[TexasRain104]

A Riva e cig from Vaporescence...

and what ever battery purchased to make it 3.7v

 

[GrannyM]

I think a Riva is a bigger batt 510, but I could be wrong, lol. Anywho, the 510 batteries have a lower voltage than the KR808, (maybe 3.2?), so that probably accounts for the difference.

Edit to add: I don't have any 510's or the Riva, but just checked in the forum elsewhere where someone posted that the Tornado/Ego/Riva all are at 3.2 v. So, I'm sure the difference in the voltages explains the differences for you & your friend.

Thanks, Ill await your analysis before deciding to purchase or not (this time)

Sounds like maybe you better check resistance while at it (according to the quote from Leaford above "They have a higher resistance than our Premium Blanks"...)

You know ...someone should be paying you for all this !!

 

[leaford]

The Premium cartos have 2 ohm resistance, and the Coolcarts have about 3.5. V4L batteries run at 4.2volts on a full charge, dropping to about 3.7. 510s (including the ego/riva/etc) run at only 3.2volts or so.

I disagree with Addy that you shouldn't use Peemies or Cools on 5v, I use them on my passthrough all the time.

And there's no difference between battery lengths, so you don't need to use particular batteries for a particular type of carto.

 

[Adrenalynn]

Ok, Leaf. What's the USB standard max current draw in order to bear the USB logo, and what is the current draw with a premium carto?

 

[CatMommy]

So, I have to ask/put this out there:

Is there anything in the works for a V4L HV carto to be used on a 6v mod?

First... Thankyou for the help, and this goes out to everyone else as well.

Second... Leaford... premies... not "pee"mies. Thats going to take some time to get rid of the mental image.

LOL

Yes, I know I'm not Leaford...

Good question.
If I were a usb developer, I'd probably have to know the answer.
Best I could find is:
Portable Device attached to Dedicated Charging Port can operate up to 5.25V and 1.8A

There are currently two types of cartos being distributed through V4L as Premium (most of them are the newer style, but there are still old ones out there).

The older premium is slightly longer and comes with a glued in hard cap and a 3.0-3.3 ohm resistance range.

The newer premium is shorter and comes with a softcap and 2.2-2.5 ohm resistance range.

Now, they have brought the old style back, but with softcaps, made them blanks and distributed as Cool-Carts (named obviously due to the higher resistance.)

I honestly prefer the lower resistance cartos, even at 5V (my usb PT measured at 5.09 V). Actually I love mine a 5V.
The higher resistance cartos just don't give me the throat hit and vapor I want, especially with 3.7v batteries.

Now my question is to Adrenalynn - What is it (from an electrical engineering standpoint) that is not reasonable, to be operating a device at 5V at 2.3 ohm resistance? Amperes too high?

 

[Adrenalynn]

USB Charging is a "non-standard" (draft) at present. 500mA * 2 on a single root is the USB 2.0 standard. But even given the 1.8A of USB Charging and assuming we're just going for the immediate future and adopting the draft:

Ohms law states: I = V/R, but would more properly be stated as V/I = ΔV/ΔI = R

We can way over-simplify (over-simplify because we really need the voltage AFTER the resistance) and just take it as:

Amps = Volts / Resistance

Amps = 5 / 2.3 = 2.174

Of course, that's simple wire resistance assuming ΔV = 5v . Heat raises resistance, some of the batteries are PWM, etc. The upshot being that we observe up to around 1.78A right now. Well outside of any safety margin for USB compliance.

The engineers designing the low resistance cartomizers never intended them to be used outside of their design envelop, that's pretty clear.
