V-Drop on VV eGo on partial Discharge

[VirusZ]

Hi,
I noticed reduction in vapor on VV eGo, so I measured it with multimeter without load and on partial discharge (3 lines left) the 4.2V was 3.8V, 3.7V was 3.2V and 3.2V was 3V.

Can someone else measure it and see what happens?

Thanks

I measured mine at 3 bars with a voltmeter and it's 3.7v. I don't think it's supposed to maintain at 4.2v unless it was mentioned somewhere and I didn't see it. I did get 4.17v fresh off the charger.

it seems to drops off a few points, some more then others. others had it at 3.9 at the 4.2 setting half drained.

you shoot dual coils at it and various other stuff you may get varyign results but under no load it provides what it states with a full charged battery; with the battery half charged or less it still provides a high, medium, low setting. We don't know exactly what the electronics do inside these and it capability with any said lithium battery without gettign intothe weeds but the bottom line is it provides a low, medium high a full charge and as a battery discharges.

The manufatcurer told us it provides what it does under no-load but even in the manual it only states a low, medium and higher expereicne, whatever that may fall at dependig non the charge of the battery and i assume you won't see a ton of difference until you get to a third of its charge. At that point you can either recharge or keep vaping at the settign wwhcih works for you best

Well at least it work, better then any eGo or Riva, Im very happy about the VV eGo.
Maybe they will fix it in next revision or make a 1000Mah device......

P.S. I sent you a PM's mate, can you check your messages

hmmmmm, that does sound interesting virus

Ah ok..
I didn't measured on load just pressed the button, I dont have the tools to measure on load...

Thank you for testing...

I had an idea to disassemble 1000Mah Ego PT, and swap the electronics from the VV to the PT and see what happens.
I will loose the battery indicator but in theory I should gain 1000Mah bat and USB port

hmmmmm, that does sound interesting virus

be patient mr virus, patience my friend

The only way you can get the exact voltages at each of those 3 settings with a battery is the device would have to have whatever the Provari has in it to boost the voltage of a battery that is not fully charged. The Darwin has a 12.9 V 1800 mah (I think) battery that can deliver 6 amps so even when not fully charged it still can deliver the needed voltage and current to get the desired power setting. I would think the variable voltage pass through would be able to always deliver 3.2, 3.7, 4.2 V

Here are some unloaded and loaded measurements made by my friend ITA:

[COLOR="black"]Atty resistance: 3 Ohms

Vu - Voltage unloaded
VL - Voltage under load

Fully charged - 5 led bars: 
Vu:   red: 3.03-3.3V;   purple: 3.70-3.8V ;   blue: 4.2V
VL:   red: 2.80-3.1V;   purple: 3.46-3.6V ;   blue: 3.9V

With 3 charge led bars (while working):
Vu -   red: 2.82-3.11V;   purple: 3.47-3.60V ;   blue: 3.90V
VL -   red: 2.65-2.92V;   purple: 3.26-3.39V ;   blue: 3.68V

Going to 2 charge led bars (while working) - end of charge:
Vu:   red: 2.68-2.95V ;   purple: 3.28-3.41V ;   blue: 3.69V
VL:   red: 2.52-2.76V ;   purple: 3.10-3.21V ;   blue: 3.49V[/COLOR][/B]

not bad and im sure it can get better, not bad for whats it doing at all .

Would have to agree with that.
And the actual usage experience is very good.

Nope mate, the opposite is true (tested already).
The VV PT had MAJOR V-Drop on load.
I got it day one, was maybe the first or second customer...
The VV eGo is WAY WAY better, the VV PT on highest settings had less vapor then Joye 1000Mah PT on 3.4V

as I said earlier, this one is the best eGo type device, Its a Fact.
But obviously it can be better, like 1000Mah, USB port and better voltage regulator

... and an OFF setting.
... and a better button.

 

[VirusZ]

yeah mate that too
And a new LCD screen like in GotVapes Volt that actually shows the voltage used

... and an OFF setting.
... and a better button.

 

[ita]

Well, they could skip the 3.X V modes and try to make one with 4, 5 and 6V instead

 

[robl45]

so it won't hold 3.7 the whole time while vaping? that ruins it for me.
