I stand corrected. I am however a little confused. As I stated before, I've used the Provari's with AW IMR 18650's, 18490's, and 18350's. So, I decided to do a little test. I took my Mini and put in a fresh AW IMR 18350 battery and a new 3.0 boge carto in my Lavatank. I vaped it exclusively and got 10 hours before the light started blinking using a full 3ml of juice. I then put in another fresh battery and changeto a 2.0 boge carto in a different tank getting just under 8 hours before the light blinked and using about the same amount of juice. So, Str8V8ping is correct. The batteries last longer with the higher resistance carto's.

Now what I'm confused about is I've never been able to get more than about 10 hours out of a 18490 and around 14 out of a 18650. Could it be because my other Provari's are V1's? I started the same test with the 18490 in the Mini and amcurious as to what kind of runtime I'll get with it.

Maybe your 18490's are not holding charge .Shouldnt really measure by time tough as theres a million variables like how long the button was pressed each vape,Actual run time etc. Best is to test by mls . I get 1 3/4 lava tanks full with the 18490 and just under 1 lava tank full with the 18350 .Those numbers make sense to considering each batts mah rating .

I did get just under a full Lavatank out of the 18350, but I'm not even going to get 1 1/2 tanks out of the 18490's. The 18490's are about 8 months old so they might be starting to get a little weaker I did notice one other difference as well. On the Mini, the light starts blinking at 3.2v and on my V1's at 3.5v.

I think thats the problem . The 18490 is really old.I recommend changing it since you never know what will happen when it goes. Think of battery age as 10 years old for every month . A 8 year old battery is like a 80 year old man. A 80 year old mans not going to perform well and most likely will die soon. I always go by that.

3.5 low battery light is a bit strange. My light on both my v1 and v2 go on at 3.2-.3.3v

You're disregarding that in order to boost to 5.2V, the battery is providing more than the 1.7A's going into the cartomiser. Boost circuits don't magically add extra power to the system, more current has to be drawn from the battery (one of the reasons for the use of IMR).

Assuming a 100% efficient boost circuit, you'd be pulling approx 2.4A off the battery in both those setups and have the same battery life.

Of course it won't be 100% efficient, and the efficiency will vary with V, so there will be some minor difference in battery life between different Voltage/Resistance setups.
I'm not sure I understand, since I figured that the decreased amp draw from a higher resistance atty delivering the same wattage would be easier on the battery than a lower resistance one. Boost circuit aside, higher resistances draw less amperage given a set wattage so wouldn't that take less battery power? Considering that with a higher resistance, the mod is "asking" for less power from the boost circuit? I'm no electrical engineer and wouldn't say I'm knowledgable on the subject though so I'm curious.

Well, if you put the boost circuit aside, then yes, the less amperage for a set wattage would take less battery power, however in that circumstance, you are limited to 3.7V.

In the case of Provari Mini we are discussing, we are varying the voltage, using the boost circuit, the battery is still providing all the Power, therefore any calculation of the amperage drain on the battery must be done using its actual potential (voltage) which is nominally 3.7V.

If the boost circuit achieved the impossible 100% efficiency level (Power in == Power out), you'd be drawing the same current from the battery to drive either resistance at the same power level. Therefore, your battery life will be identical.

Think of the boost circuit as a power converter, if you are using 9 Watts at 5V, 6V or 4V, the drain on the battery is 2.43Amps (3.7V x 2.43A = 9Watts).

In reality the efficiency is probably more like 90%, so 9 Watts output requires 10 Watts from battery = 2.7A.

3.7 is pretty low for a 1.5dcc but id guess around 3-4 hours.DCC's never get good battery life which is one of the many things why i dislike dcc's

Just bought my first vv tube and only getting about 2 hours out of it and that's only if i have it set at 3.7 anything higher than that is a lot less time. Was using a 900 mah ego battery with the same 1.5 dcc and it would last me about 7 hours . What should I be using to get better battery life ?

Single coil cartos .Boges imo perform so much better then DC's as well. That doesnt seem right at less then 2 hours. WHat battery and vv mod are you using.

That seems unusually low, I use a 1.5 DCT daily and generally get around 3-5 hours use (About 1.5-2.0ml juice) on a 18350, but I'm running it at 4.8V.

As I am sure others have mentioned earlier, time is a difficult measurement because we all vape differently, juice consumption is a bit better. But you are comparing to a standard Ego battery, and I would certainly expect most VV mods to exceed that with the same vaping habits.

What VV are you using? and what batteries? perhaps the batteries can't keep up with the drain required? (although at 3.7V that shouldn't really be an issue).

Am using the mininova from V9 and the bats that came with it they are High Drain 18350 Rechargeable Battery 700 mah.
I just ordered a AW IMR 18350 3.7v 700 mah battery to try

The thing I like about the provari is you can use it with just about anything . I use to use boge 2 ohm but now I use an ego adaptor and the kanger 2.3ml 1.8 ohm cartomizers . They are a good size and are single coil . There is no 510 connector in them so you must use an adaptor for the outer threads .

Ah thats why . You got a lavatube. I bet those battery are not really 700mah. Id be surprised if they measured out to be 400mah.
