I don't have one in my arsenal!

Should I?

If anyone has any info on this model 520? If so please feel free to shout out here.

Cheers or Jeers!

Stehle

Anybody?

You might already have one.

From what I can tell it's a 510 with a mega battery.

oh is that all? :|

Pretty much sounds like it. The 'characteristics' of any e cig is derived from the atty and the carts, or cartomizers. The only other component is a power source. Building a power source is eashy. I have one 18650 (2200 battery) that was 'donated for destructive testing' (I seem to have this reputation around here!) and two powered mods, one that plugs into my ciggy lighter and one that plugs into my computer (NOT usb!! I mean, you REALLY plug it into the computer!!!) And I wonder why I'm blowing attys all the time?

Anyway, aside from that, the atomizer is what really is the e cig. So anything that uses a 510 atomizer is going to act like a 510, a 901 like a 901, etc. The problem is, with a standard battery, you start at 4.2 volts for a few puffs, and then it settles down to 3.7 volts for most of it's life before it has to be recharged. Once it hits ~3.4 volts the vapor gets weak, and on Joye 510's, the LED starts flashing and it shuts off at ~3.2 volts. This is to keep from going below 2.5 Volts, which is VERY bad for a lithium Ion battery. Very bad in that they kind of melt down and explode...

Enough scary stuff...a battery mod stuffs a larger battery into whatever housing you can make/find, and the bigger the capacity (std is 280, a Mega is ~900, and homemades are ~2200). The bigger the capacity, the longer the voltage stays at 3.7, which is where we want to be (well, we really want to be at 4.2, but that level fades fairly quickly. I charged the 2200 Friday night overnight, used it about 2 hours Saturday and an hour today, and it's still at 4 volts. That makes nice vapor...)

What it really comes down to is watts. The higher the wattage, the better the cloud. At 5V the wattage is 10 watts, more than enough. At 4V the wattage is about 6.4, enough to cook the juice good. At 3.7V the wattage is about 5.5, still not bad, but below that the vapor starts to get weak.
So a battery with more capacity will hold a higher voltage longer and make stronger vapor longer. That's actually a secondary concern for some. If you're like me, you use up a standard battery in one session, and have to keep 2-3 batteries and a charger handy. I got sick of that, and have 2 mods and my plug-in mods. If I'm home or in the car, I hardly ever use a battery! When I do use a battery, one of the larger capacity mods keeps me puffin' till I can get back to the car or home.

Hope that explains it a little bit! Now, if I can just keep from burning out attys...

Stehle

Yes quite, but does this have the higher ohm atti?

The way I understand it, that atti might be better for higher voltages. (hotter vape? mods?)

I was also informed it may be thinner than a standard 510.

(Perhaps I was just misinformed.)

Thanks guys and gals I always get the straight dope here!

I don't think it has the higher resistance atty, those just won't work worth a crap on a regular 3.7 volt power source. The High Volt (higher resistance) atty primarily reduces the current flowing to a level that won't FRY the atty at 5 to 6 volts from a High Voltage MOD. A single battery mod that runs off 3.7 volt batteries only gives you more hours of vaping than a small battery. A regular atty on 5 volts gets hotter but "some people" have experienced reduced life using a regular atty on high volts.

I hope the 520 is not thinner than a 510. That would reduce space for the Li-ion battery inside. Ain't much in there as it is.

To give you an idea of battery life (i.e. vaping hours) here is a cell photo (emailed, reduced, really crappy and fuzzy) of a regular 510 battery next to an 18650. Both start out at 4.2 volts and then fall as you vape (one falls faster than the other). The 510 Mega battery is longer than the regular 510. I'll replace the photo tonight from the house with a Mega included.

Newton was wrong. The bigger battery falls slower, much slower.

Thank you for the clarification Rocket! Happy Holidays!

Any first year electronics instructor tells his class: Electricity is like water. The current is the water, the voltage is the water pressure, and the load is a resistance to the flow.

Using that, the atomizer is the load. The current (measured in amps) is the amount of electricity flowing through the atty and the battery is the supply.

With a higher ohm atty, you need a bigger supply to get current flowing through it, therefore a higher voltage. That's why the places selling the 5V atomizers say they won't work with a regular battery, It will take a lot longer to get the temperature of the atty high enough to vaporize the mixture.

I'm thinking of getting one of these to see what happens. I'm running 4.2V in my mods, which should emulate a fully charged battery, but the circuit I'm using is capable of delivering 2.25 amps. You can push current through just about any load, but by pushing it through you shorten the life of the load. Could be what's happening with my mods.

An e-cig is all very fundamental. Ohm's Law, nothing more. But I think when an atty starts to die, it's resistance decreases, and therefore allows a lot more current to flow through it, until it burns the heating element and breaks the connection. A broken connection allows NO current to flow!

Yikes Even!!!! Think I just got a free electronics lesson, I'm still figuring out the whole vapeing process.(Brain explosion)hahahaha

Steampunk

It's all quite simple, until you get into the MOSFETS used to control flow at the push of a button.

THen you need a Rocket Scientist..or JJ...

gmama55

Ok still don't got it hehe, I'll just keep vapeing and I will get there, Hmmmmm, maybe not hehehehe

berger

How about lower voltage vaping with NiZn batteries (safer)
higher current lesser voltage...now that is cool ....errr... hot

Steampunk

LiFePo batteries are getting more plentiful and cheaper, 3.2V, charge like Li Ions but don't go <BOOM!>

berger

Is that because apple is using them?

Steampunk

Hmmm..are they?

berger

I was looking at macbookpros yesterday (for somebody else)
and all had LiPo batteries
I think a lot of their stuff does

chicopee

Brilliant! I printed a copy of your explanation for future reference - thanks. I had some of it in Physics back in the Ice Age. I forgot this stuff.

Awe man! You've already had to live through another Global Warming! What a bummer!

berger

Actually theres a global cooling problem developing
check the history this will be the 3rd time since the 1800's
Total BS - just to work up grant money

Rose

I know. It's all a big joke

berger

Im just saying that will be the next global crisis (again)

Steampunk

LOL! http://www.global-warming-and-the-cl...-core-data.gif

Take a look at the URL...I guess the chart on their web site doesn't give them a clue.
No surprise there...

Steampunk

Look at the link I posted...it's from a Global Warming web site.
The chart shows that the heating period occurs every 150,000 years (give or take 10,000...a geological wink....) and that we are at the end of one of the 150,000 year cycles.

SO, is this dire cold snap this month just a glitch in the "Earth is going to burn" fad....

Or the signal of what's to come? If there isn't any oil left, and they don't start working on some replacement soon, it's going to be REAL COLD for some! The last glacier to cover the US made it through Penn. Now, the current 'glacier' is at the Arctic circle, so with ice in PA, what is Florida going to feel like?

Rose

I know that it's just a cycle. But some folks are freaking out.... stupid,stupid, people
