Increasing voltage of electronic cigarette

[frotsmud20]

http://www.e-cigarette-forum.com/forum/joye-510/65055-battery-voltages-surprise.html

Scottbee goes through the process of checking the voltage of electronic cigarettes:

1. I am not sure exactly how he hooked the battery up to the dvm (as in the contraption the battery is hooked up to), if somebody could tell me how to do that I would appreciate it.

2. Is there a way to increase the volts that an ecig puts out? I have a Joye510, and if it needs to be upped a bit to get to 3.7 v's, then I'd like to get it up there.

Thanks in advance.

The digital volt meter has a positive lead and a negative one and these are placed at the battery connector to the center pole and the threads. Scottbee did this with adding a resistor to simulate voltage under load. He also discovered a resistor in the ego battery responsible for the voltage drop and bypassed it. I don't believe he has said yet which one.

 

[frotsmud20]

Still a little bit confused here asdaq, bear with me (plz):

Why would you simulate voltage under load?

What resistor did he use to simulate the voltage under load (I guess that's where the problem lies; you have a positive and negative charge cable and you just put those on the battery threads is what you are saying (to my understanding). So where exactly does the resistor go/what is it/why not just push the button instead of using a resistor?)

He has however definitely found a resistor in the eGo that keeps it below what the marketed voltage is, am I correct?

 

[asdaq]

Simply to measure the voltage of the battery while it is firing an atty (working under load). Since an atty has a given resistance, he used a wire wound resistor of 2.5 Ω between the positive and negative leads to simulate this strain on the battery. And yes he found which resistor in the circuitry is responsible for this reduced voltage in the ego. Calling it marketed voltage isn't really fair as it is a '3.7v device' in that the power source is indeed a 3.7v battery, what happens to the voltage later is secret sauce. To be fair, an ego batt delivers the same voltage right up until the charge is too low, giving the vaper a balanced vape throughout the cycle. Disabling the resistor defeats this feature too, but he also made a handy charging stand that keeps the battery topped off when not vaping... unless he goes somewhere far from the charger.

 

[frotsmud20]

So if you disable the resistor, the voltage continually drops as the battery drops?

And when you say the eGo battery delivers the same voltage right up until the charge is too low, you mean it delivers the 3.0 that Scottbee tested it as? If so are Joye e-cigs naturally bound to run below 3.7 and would have to get a different e-cig (I assume the Kanger that he tested since it runs at 3.7) in order to have it run there?

would I*
in order to have it run at 3.7 volts**

Sorry a few typos.

Basically I'm just trying to figure out what I need to do to get an actual 3.7 volt ecig, then put a low resistance atomizer on there b/c what I am getting from reading other forums is low resistance atomizer= lower battery but greater vapor/flavor, and finally I want to add a drip tip because from what I've read they work well but I still need to research exactly how that works before going about it.

If you want a 3.yvolt battery you can get a KR 808. They run at 3.7. The voltage will drop as it is being used. Liberty Flights also has a Riva that runs at 3.7.

You should ask to make sure. Despite what the specs say.

If you use a lower ohm carto you will get the same affect as using a higher voltage battery.
Lower ohms gives you more watts or power to the coil.
Higher voltage does the same thing.
Hence more hit and smoke.

Does the manufacturer say that they run at 3.7 or do they actually run at 3.7?

 

[frotsmud20]

^That is just something I am wondering about because as Scottbee showed, it may say 3.7 but run at 3.0.

Scottbee tested one of these a few weeks ago and it was a true 3.7. Others ran at 3.O. Don't assume that the other vendors are selling the same one. Personally I wouldn't go by the what the manufacturer say because you can't tell if it's the same model you are buying. Here's the thread:

You may have to go back a week or three. I haven't looked at it recently.

I read over his thread last night and everything, I'm just wondering how would I know if the one I am buying is an actual 3.7 as marketed instead of a 3.0 like Scottbee showed some of the ecigs to be? Or if you really can't know how you would modify a 510 or an eGo to 3.7 instead of 3.0?

 

[jufreese]

any guaranteed 3.7v battery will be 4.2v fully charged. But even fully charged, as soon as you press the button, the battery will drop at least .2v.

When you press the button on an Eqo with a catridge it will drop to 3.2. A KR808 will drop to 3.7 same with most american mods and some Rivas. I don't care what voltage it runs at without a carto.

You have to ask the vendor if he tested it under load or if he will guarantee the rubbing voltage under load.
As far as I know at this time all of the KR 808's are true 3.7 batteries.
GotVapes has started to sell 3.7 volt VGO's. you can ask about it here:

Bad will answer any questions you have.

Or if you really can't know how you would modify a 510 or an Ego to 3.7 instead of 3.0?

You can ask on the other thread or the moders forum. It doesn't look like you are going to find someone with an answer here.
