That's a snazzy looking cone you got there MatrixTech where did you get that from?

 

[zoiDman]

Right on....

To me that looks like a drip shield from empire mods. They look cool. I may be wrong.

You are correct thanks

I don't know anything other than the research I've done on my own, but I understand the batteries are 650mAh. If GotVapes will sell the batteries separately that'd be wicked cool. The only way I've been able to find this beast is as part of a kit

just wondering how 4.2V will perform on a 650-700mah in terms of vaping hours considering it has a lighted ring and an LED indicator to supply with. Oh by the way thus it measured 4.2 volts under load?

 

[MasterofChaos]

Does this device contain a booster circuit?

If not, then how does it maintain its 4.2V output?

 

[badkolo]

I have been told it has a circuit inside and when you switch to 3.7 it stay around 3.6 to 3.7 and when you switch to 4.2 it stay at 4.1 to 4.2 and does not drop. each voltage stays at the voltage chosen. this is what I have been told to let you guys and gals know.

 

[MasterofChaos]

Okay then, so if it maintains the voltage at 4.2 volts then the only way it can do that using a single lithium cell is if it has a booster circuit.

If that is true, then that is quite a impressive little device, since booster circuits require large inductors and capacitors that would be very hard to build into such a small form factor, never mind being able to retail the whole unit for $30, with the LED battery indicator and all.

Here's another question: If it maintains the 4.2 volts, which means it has to have a booster circuit, why would you limit the maximum voltage to the same maximum voltage as the battery? I mean, if there is a booster in there, why not make it some other voltage like 4.5 volts, or 5.0 volts, or whatever?

You can choose any voltage you want, so why make it the same as the maximum voltage as the battery?

Thanks for answering my questions.

 

[arjay55]

To my way of thinking this is a inexpensive way to try out variable voltages without going all out on buying a provari (etc) and finding you don't like the super high voltages. $30 compared to a couple of hundred seems a good deal to . I have thought about getting a vv-mod and this can give me an insight.

I don't really care if it's .1 or .5 of a volt off the stated figures. I guess they have a +/- built in to them anyway. As long as the starting point is the same as my ego/ego-t batteries then the rest is a bonus.

If someone is so intent on having perfect voltages all the time, every time, they should maybe be looking at something waaay more expensive. imo of course

 

[MasterofChaos]

Arjay,

That's fine if you are okay with the voltages being off, however the specific voltages ARE claimed by GV. If they claim it, then it must be true, no? So I am just trying to figure out how the unit does this, is all.

I have another question:

Is this unit made by Joye or some other manufacturer?

Thank you for your response.

 

[badkolo]

When i get full technical details ill let you guys know here.


Ill get further info for you all and reply here when I do so.

thanks

The eGo variable is indeed a bit longer than a standard 650 battery to account for the electronics...

Why they dodn't go to 5v? I am not exactly sure but it does vary between the three popular voltages with enough difference in the three that gives a different experience between those three levels. As far as the variance...a variance is a variance. You have variances with every atomizer and cartomizer ohms on just about all stated products. The manufacturer told us there is a variance at each voltage setting.

Okay then, so if it maintains the voltage at 4.2 volts then the only way it can do that using a single lithium cell is if it has a booster circuit.

If that is true, then that is quite a impressive little device, since booster circuits require large inductors and capacitors that would be very hard to build into such a small form factor, never mind being able to retail the whole unit for $30, with the LED battery indicator and all.

Voltages measured without load:

(Charged battery)
- low: 3.15V
- medium: 3.77V
- high: 4.18V

(Half charged battery)
- low: 2.9V
- medium: 3.5V
- high: 3.9V

(discharged + 1 minute charge)
- low: 2.7V
- medium: 3.2V
- high: 3.6V

Correct me if I'm wrong, but that doesn't look like its maintaining anything. Its not even keeping the voltages constant sans load as the battery discharges. If it drops that much without a load, when a load is applied it will drop considerably more. pmos, can you make some measurements with a load attached?

BadKolo,

Can you please comment on this? His measurement results would seem to be counter to your assertion that the battery maintains the voltage as its discharged.

And yes, if you could supply the full technical details that would be much appreciated. Specifically I would like to know if the unit has a booster circuit in there or not, for reasons I have already outlined.

Dannoman - If there is a variance at each voltage setting, then what is it? If 3.7V is not 3.7V, then what is the correct voltage?
The manufacturer will know what the real values are, and should be able to supply you with a tolerence value for each setting.

 

[dannoman]

I would imagine it does have booster circuitry (I can ask the manufacturer for sure for you, but common sense would seem to dictate that as the battery discharges a booster would be needed to raise the voltage) and as the manufacturer stated there can be a +/- .1 variance...

It is the weekend in China but they often come on sometimes on their Saturdays...

 

[pmos69]

pmos, can you make some measurements with a load attached?

Unfortunately, not at this time. haven't got suitable gear where I am.
Sorry.

There has to be a booster in there, or else it would have to have 2 cells.
(3.9V at mid charge is quite a lot)

If it's a single cell in there, I would guess the regulator has to be some sort of hibrid (switching + boost?)

Compensation is what seems not to be that efficient. (On the other hand, maybe it only works well under load...)
Well, this is only my unit. Perhaps others have different results.

Not bad , thank for the measurements, so it holds it load and drop offs at half battery, nice to know. thanks.

 

[GiMante]

Just got mine today, working rather well. Thinking of buying a whole set when the SS is stocked again

View attachment 49041

Only things I don't care for is the loose button and the cutoff time, hoping the price goes down abit, liking the VV

I check the site everyday

Thank you GotVapes!!

MT, that is sharp! How you liking it?

Haven't read the whole thread but Healthcabin do a 4.2v echo battery which fits 510 threads.

Haven't read the whole thread but Healthcabin do a 4.2v echo battery which fits 510 threads.

Most lithium cells give 4.2V for a very short time when fully charged.
Thy quickly drop to around 3.7V for most of the charge lifetime.
