Shortened 18650 Battery Life

[mikebabs]

Interested to see if anyone else is experiencing shortened battery life when switching over to variable voltage.
Im a long time user of the Silver Bullet with Dual Coil 1.5 ohm cartomizers. I could EASILY get around 6 hours of heavy vaping using an 18650 battery.
Enter the Lavatube. I cannot speak to other VV devices as I dont own one.
What I have noticed is a SIGNIFICANT decrease in battery life, at least half of what it used to be with the above method.
I have been using 3 ohm cartomizers in the lavatuve at between 4 to 5 volts and quickly see the dropping voltage of the battery.
I have been thinking, this is not very efficient....I understand that the voltage is more regulated with the VV, but at what cost?
I always enjoyed dual coils at 3.7 volts and am beginning to wonder if the higher voltage with higher ohm (high resistance) cartomizers is simply a battery killer.....especially with an 18650....protected or unprotected, IMR or not, I have them all...
Any thoughts or comments??

When you say heavy vaping, how many ml's do you vape in that 6 hour period? Thanks.

If you set your V V device at 3.7 or 3.8 its not going to affect the battery life in my experience, but when vaping at a higher voltage like say 5V to 6V your using more energy so naturally the battery life is shorter. However, V V devices are used for versatility, say you have a HR atty and some juice that vapes best at 5.5 or 6 Volts, then you would experience less battery life than if vaping on a 1.5ohm dual coil cart at 3.7 volts. Variable Voltage is for options not for battery longevity..IMHO

I can vape 1.5 mils in 5-6 hours, IMHO I think thats pretty heavy...not sure what others do....As for setting the VV, especially the lavatube at 3.7 to 3.8, my experience has shown that to be a WASTE of time...the LT doesnt like LR cartos and anything above, lets say 2.0 ohm to 3 ohm at 3.7 to 3.8 just will not provide enough power to heat the coil....
Im thinking about a provari for truly regulated voltage using a Dual Coil 1.5 carto.....
The Lavatube just cannot do that....
As I said in the original post, I have nothing to compare it too as I only have the LT...
Im beginning to think there is WAY too much hype with the Lavatube....
Its just too bad it doenst like dual coil stuff and additionally bad it doesnt really regulate anything....

Not sure about the efficiency of the LavaTube regulator, but yes, it will drop the usage on a given battery. Of course, with VV its so easy to turn up the power higher than you would get with 3.7 on a 1.5 ohm carto. The recommended high drain IMR's do have a lower capacity...

studio52 hit the nail on the head, I notice the same thing with my provari.
