well mine is the very first release and i like it a lot so the newer ones can only get better...

This is the reason why I'm holding off. Once this comes out with the USB passthrough, I will be like "Shutup and TAKE MY MONEY!"
Will sneak up on bad, hold a gun to his head, and hand him my wallet. "Put the new battery down, and take my credit card, or you know what'll happen." XD
A multiple, multiple dual here: http://www.e-cigarette-forum.com/fo...-pictures-brighten-your-day-just-relax-9.html at post #83. With more volume, the length of draw may be reduced.
Pretty sure that what you will find on the oscilloscope is all three levels of selection are pulse width modulated - and no boost present. Low will have a duty rate of about 76%, mid-range at about 90% and high 99% or so. AC measurements are showing about 1.6 at low, about 0.9 at mid-range and very small at high but not zero. At same time I read the AC, DC read 2.77 at low, 3.33 at mid-range and 3.76 at high. The AC and DC reads suggest RMS values of 3.21 at low, 3.45 at mid-range and 3.76 at high. These numbers suggest that power at mid-selection is about 84% of power at high and power at low about 73% of high. Had readings perhaps been more precise and accurate I think the RMS values would have turned to have produced power reductions identical to the duty rate percentages.
It seems to me the VV eGo is a hybrid of a Joye eGo and a Riva. Joye eGo varies the duty cycle of the PWM output so as to produce a consistent DC reading and, I think, relatively consistent power output throughout its discharge cycle life. Riva does not modulate and as a result produces greater power output in early stages as compared to eGo but less toward the end. The VV eGo is basically a Riva at its high selection and is a moderated Riva at the other two selection levels using PWM to achieve the moderation.
Not meaning to derail the thread but this is the reason I think I'm gonna use KGO batteries instead - as soon as someone gets some in.

That level of efficiency for the blue setting from a PWM circuit is unlikely.
Even more when the previous "DC" readings (most likely flawed) show a performance a bit higher than a simple li-ion bat.
About RMS. You need a "true RMS" voltmeter.
AC readings and "average RMS" or similar readings should be more or less flawed, since the device output is most likely a square wave.

Which "previous" DC? Are you saying a 99% duty cycle is unlikely?
I do want to make a quick point for newcomers seeing this thread, you dont need to go through all of this to enjoy your led 3 stage variable ego, simply charge it and screw on your cart,tank or atty and choose one of the 3 levels to achieve your desired vaping experience.
To the techies of this thread, thanks for all your input, its much appreciated and helps everyone with a better understanding as to what makes these cool 3 stage ego's tick but try to enjoy your batteries a little more because before you guys are done investigating this one, 3 others will be arriving ,hehe funtimes ahead.

Is "mine" the same as listed at post #220 (pg 22)? If so, those readings tend to substantiate 99%+ duty at high (blue) IMO. I took other readings and likewise confirmed the very high duty rate. It is seeming to me that mid-select (purple) is very, very close to eGo for most of discharge cycle and other two are plus or minus ~10% power of mid-select.
Think maybe we should open another thread if you want to keep discussing this.
Perhaps this is just a bit too tech for the OT.
(What I was telling you is that I don't know of any low voltage pwm circuits with 99%+ efficiency, so to get those end results you need to pre-boost the signal. Open another thread if you want to discuss it.)

here is just fine, it can stay in this thread, or you can do a separate, whatever floats your boat guys ,all good , no worries
Gotvapes website has posted to contact us does that mean they are out of stock? thank you.
First, I love this damn battery. I was disappointed with my Smoktech eGo batts when I used anything other than dual coil cartos. I wound up sticking my last box of CE2's on a passthrough, because those batteries just didn't cut it. I was saving up for a VV mod til I saw these, and decided to wait for more stock to come in. After just a few days with one of these, I'm seriously considering buying a couple more and giving my old batteries to a friend.
I just have one confusing (non-)issue with this: if I set it to 3.7v, the ring eventually flashes red and steps down to 3.2v while I'm vaping. It doesn't happen often, and it never happens at 4.2v. It's not even an inconvenience to me, but I'm wondering if this is actually a feature. Is there some programmed way to lower the voltage, rather than just hitting the button ten times?
