Help undersatnding LR and HV atties

[themysterious1]

Ok I hear all the hype over the new IKV i06 atties but im not sure witch to order to try? I see all of there atties are either LR or HV. I have never used LR or HV atties b4 I just buy regular atties. So I would use them on my Red Sky VV mod and what would somebody suggest to get? I usually buy 2.5 ohm regular atties. All this technology LOL. Thanks

They are for the guys who can't figure out how to use a simple 510 or 3.7 volt ego so they waste a bunch of money on a high voltage mod. A 3.7 ego with an 1.5-2.8 510 or lr306 atomizer will perform just fine. Are the I atty still $75?

I have no idea about the I Atty never looked into them. Just was hearing how long these lasted and how they performed so I thought I would try one out.

Nice... 3.7 volt fanboys and gals... but it doesn't answer the OPs question.

BTW. Standard atties last longer than LR atties. Usually, the way they make LR is to use smaller (shorter) coils (Less wire = less resistance).

IDK about HV atties, I use standard atties (3.0 ohms) at 5 volts (regulated). That's the other nice thing about vv mods... voltage regulators so you don't have to follow battery voltage. And with vv, it is adjustable.

Anyway... It's mostly about the watts (power). I'd do the math for you in this response, but you didn't say what voltage you normally use for those 2.5 ohm atties. The equation is V*V / R. V is the voltage (squared as the numerator) and R is the atty ohms (resistance). So for me, 5 volts and 3.0 ohm is 8.33333 watts of power ((5 * 5) / 3 = 25/3 = 8.33333).

Here, use this too. Plug any two known values in and hit calc. Ohm's Law Calculator

As a general rule, the HV and SR atties will last longer than the LR atties due to more robust construction.

Since you have vv, you can use many different ohm atties and just change the voltage. Stay around standard if you wish. Note the squaring of the voltage in the equation. This implies that the device gets more efficient at higher voltages. You'd pair higher ohms with those higher voltages. This is the same reason that household 220v is more cost effective than 110 for running things like air conditioners and such.

I'd say try a few at various voltages. I don't really see the need to go above 3.0 ohms and pay a premium on HV stuff, but some love em.

He's not talking about imeo's iatty....he's talking about the io6 from IkenVape...

Thing about the io6 ..it's either a dripping or Atty for feeders from what I hear...has a bridge but no wick...510 threads and looks like a 306 but is slightly bigger so you need the io6 specific drip tip...

Since you are using vv I'd say something in a Hv range...LR you'd run real hot and burn out quickly depending on what you normally set you voltage at..

LR attys came out before vv so that you could effectively vape at the wattage produced by a 5 or 6v battery configuration ..but get the same wattage from a 3.7v battery.. HV was so you could drop your wattage from what was put out from stacked batteries (producing effectively upwards of 8.2v when they're fully charged) and not have everything taste burned or immediately pop the Atty....

That's the long story... I figure it this way... 3.7v a 1.7 ohm Atty gives you right about 8watts... any higher voltage and you want the resistance to start going up...

With a linear regulator, as opposed to a pulse width modulation regulator like the Ego, efficiency is higher toward the high end of the voltage adjustment. Turning it down to 3.7v will result in power being dissipated by the regulator chip itself and battery capacity and charge life will suffer. So, to be efficient, you need to use 3 ohm or higher atomizers to get the best charge life.

Using a LR atty turned down to 3.7v is best done on a Riva batt or something similar.

Thanks guys that has helped me out a TON. I like to vape my 2.5 atty at 5v so thats about 10 watts I like a warm vape.The thing is my atty seems to get hot b/c I like to chain vape when I vape. So I guess I will give the 3.5ohm HV out and see how it goes. I like to drip sometime plus I have a bottom feeder so it should work good.

I = V/R & P = IV, so either higher voltage or lower res should in theory have roughly the same effect: more current, which at constant voltage means more power (wattage). In practice, the battery can only reach a certain amount of current before the voltage drops off. Otherwise, if you took resistance down to zero, you would have infinite current.

All of this is rendered somewhat moot by the VV mod. If you're stuck with one (or often 2) voltage, you have to find the proper resistance of atomizer to achieve the desired output. With variable voltage, you can be more flexible with resistance.

Ego is *not* 3.7v, btw.

Just to put a finer point on it, eGo batteries are 3.3 Volt output, with a 650mAh rating, with 1000mAh rated batteries available.
