Trying to figure out what point your are trying to make.
For instance, if on an electronic mod such as the eVic I increase the voltage, the wattage indicator also goes up and the batteries run down faster. Or have I misunderstood something?
Andrew Wong is his name .... wonder if he has the little (AW) sticker trademarked?
I think Rader is messing with us....
He does have a point though.....
Just talking about how long you vape at any particular voltage means nothing without considering the resistance of your atomizer.
If we were talking wattage it would be more specific.
For example: you can vape at say 12W running 4V or 6V. You just need to attach the proper atomizer.

Doubt I will be vaping at 6V very often but I was curious how vaping at higher volts affects a smaller battery like the 18350.
Your replies are appreciated!

Not messing, just asking some thought provoking questions.
In your example, both configurations would have equal battery life because the power is equal. Voltage alone has no indication of battery life.
Yup, a 4Ω atty at 6v would last a heck of a lot longer than a .3Ω atty at 3.7v, even if it's the same batt.
Whoa!
That .3 ohm atty would blow your face off at 46W!
Better forget the AW and Efest and go for them MNKE bats if you're gonna go there!

IMR is slowly, but surely going toward a retirement.
Now when 2 best batt. manufacturers are united (Panasonic-Sanyo) we can expect new much better products.
How many of you know about new Panasonic-Sanyo ncr18650-PD 2900mah?

All these newer hybrid batteries are based on IMR chemistry. The Panasonic GCR18650 that many of us use aren't true IMR either.
Will be interesting to see if Panasonic continues on the 4.35 volt path that Sanyo was going down but it's beginning to look unlikely.
I've heard that the NCR18650 is slightly thicker than most other 18650s. In which case I doubt they will fit in some mechanicals and hybrids.
Those MNKE batteries have been all the rage lately as well but I think there was a guy on youtube who load tested them and found that the AW outperformed them. Could be wrong on that .... been awhile.
Just Googled the MNKE video test.
Although not completely scientific. (He left a few variables unaccounted for)
He demonstrated an AW IMR 1600mAh delivering higher voltage under load.
I have also read that same as you stated tc1 on hybrid battery chemistry.
That said, has anyone seen a high drain battery shorted than an 18650 using any other technology than limn (IMR)?

LiPo batteries ... but they aren't generally in the same form factor as what we are use to.
Hmmm, didn't know you could do high drain with those.
I've got a 7000 mah lipo I use as a portable back up for my small electronics.
It has to do with amperage.
4v @ 2Ω = 8w @ 2amp
6v @ 4.5Ω = 8w @ 1.34amp
That isn't taking into account boost circuitry and their effect though. To my understanding stepping down voltage can be easier on the batteries, which I interpret as less amperage draw.
LiPo was invented for high drain application. They are used in the RC hobbyist field a lot ... even to power electric turbine motors.
Have any idea on what the C rating is on that battery? Let's for argument sake say it's a 15C battery ... that would be 105 ... yes 105 amps of continuous power. Something that big is probably more like 30-40C. At 30C you are looking at 210 amps.
No idea about the C rating on mine.
It has regulated outputs. (5V@1A and 5V@2.1A)
I've had it a year and a half charging twice a week. It's been a real workhorse.
I agree: 4.35V good idea, but I do not see Panasonic-Sanyo will go in that direction. They will play with chemistry instead. New 4000mAh will be based on Si. I think this is the guy. ncr18650-PD outperforms MNKE, and AW in a real world of sub-ohms (0.3 - 0.6 Ohms):
ORBTRONIC 18650 2900HD Part 2 - YouTube
0.3 Ohms - that is some serious vaping.
Thompson pretty much nailed it... It's amp draw from the battery that determines how long it lasts between charges.
The 1 thing I haven't seen mentioned yet (please forgive me if it was an I missed it), is the battery's "C rating". The C rating tells us how fast a battery can be safely discharged. It also indicates how long it can maintain its peak voltage before it starts to sag.
Basically, the higher the C rating, the greater percentage of the battery's capacity will be available at a given amp draw.
Batteries with high C rating usually have lower rated mAh rating and the batteries with high mAh rating tend to have lower C ratings.
So... Just because a high (3000 mAh) battery drops before a battery with a lower mAh (1400 or 1600), doesn't mean that the manufacturer of the 3000 mAh battery lied... It means you're using it in an application it wasn't designed for. High mAh, low C batteries are designed to deliver small amounts of power over long periods of time. Batteries with higher C ratings are designed to lots of power over shorter periods of time.
E-cigs tend to fall into the high power category
Edit... Just found this thread that gives a great example of what I said above... Notice that the Panasonic is very close to the AW and lasts longer in the 2.5 amp test but gets beat pretty handily in the 5 amp test...

It's really a shame that is is so hard to get accurate specs on most of these batteries.
With my current batch of e-liquid on my RBA it's hitting really good @ 12W.
(A little higher wattage than I have been running.)
I didn't notice anything different with my Panasonic CGR18650CH batteries, but I loaded in an Efest 18350 V2 IMR and when the battery hit 3.6V my vape became noticeably weaker. That usually didn't happen until it got solidly in the 3.5V range.
I am looking at it still charging and the next one is already to 3.8V.
It'll be interesting to compare my AW 18350's at this power level.
That is, I am curious if I'll notice the drop off at 3.6V like the Efest bats.
Crap, I took another vape and am showing 3.7V.
