The necessity of high voltage attys for 6v?

[skipjenkins]

I'm been vaping my Chuck at 3.7 since I got it, but today I got a pair of RCR123a's from madvapes just to see what all the fuss was about.

I've got 4 atomizers, all Joye afaik, that I rotate through and all work great at 3.7v. Just backstory. So I charged my 3.0v cr's and popped em in my Chuck. I drip, so I gave the atty 3 drops and took a drag. I got one weak drag, then POP, an air rush as I was drawing on the atty. I assume this is the pop of death, is this the case? Is this a foregone conclusion when using a stock 510 atty at 6v? I've heard that high-voltage attys aren't necessary, but will last longer, but I'm not so sure I should have believed that.

I'm going back to 3.7v now because I only have 3 attys left until I get some feedback to you guys. Is there a different priming sequence I should use?

Any help would be appreciated.

tl;dr I popped a normal atty the second drag at 6v, does 6v require a hv atty?

What you are looking for when vaping is a certain amount of power (heat) being delivered across the coil inside of the atomizer. To judge how much heat you are getting, you need to look at Ohm's Law. Basically

V=i*R
P=i*V = (V*V)/R

Power is equal to the square of your voltage divided by the resistance.
P=(V^2)/R
So if V=3.7, R=2.5 (stock 510 atomizer is around 2.5ohms), power is:
P=(3.7*3.7)/2.5 = 13.69/2.5 = 5.48 W (watts)

The "sweet spot" for most people is considered between 8 and 10 watts across the coil. With a higher voltage, you can see that the power increases very quickly as we step up in voltage. For example,

Given that V=6V and R=2.5
P=(6*6)/2.5 = (36)/2.5 = 14.4W

14.4W is way too much for what we want. To get around this issue, we use a "high voltage" atomizer, or, an atomizer with a higher resistance. This allows us to tone down the power to whatever we want it to be. So, with a 4.5ohm "high voltage" atty, we get:

Given V=6V and R=4.5ohm,
P=(36)/4.5=8W

So you can see, the power falls in to that "sweet spot" and you would get a nice warm vape. If you increased the resistance the heat would drop. This is also why the lr (or low resistance) atomizers are so nice. If you have a 1.7ohm atty,

V=3.7, R=1.7
P=(13.69)/1.7=~8W

We can get the same power output from a lower voltage simply by playing with the resistance. The atty blew because there was too much heat being applied to it too rapidly (and it probably dried out) and snapped. I hope this helps.

I'm gonna be honest. I understood about 25% of that. Would dripping more often, keeping button pushes short fix the problem, or should I still expect to pop my last remaining 3 attys?

Hey Skip i have never used a HV atty on my chucks at 6volts however a new one i would recommend breaking in with a 3.7 batt unless

When you attach the atty to the chuck for 6v you drop 3-4 drops take several 1-2 sec Max hits to get it broke in and keep applying drops until it
Burns less hot

and after that i do 2-4 second hits until broke in further then i do 3-5 second hits

If the atty is used it might have been too much to handle but as long as you keep it wet and take 3-5 second hits on a used atty you should be fine

I have blown one or two attys at HV mainly from being old or not breaking in properly

Hope this help!

Usually, with 3.7v I know I've dripped enough when it starts to gurgle when i draw. Is this adding enough at 6v?

Now maybe I'm wrong, but I fail to see what wattage has to do with PVs. It's my belief that the only thing that matters is the current. Current is what creates heats and the heat is what vaporizes the liquid.

Just for the record I'm an electrician, and in the field I never worry about watts, except when matching a replacement part. Not once have I asked or been asked what the wattage draw on a branch circuit is. Current draw is another story.

Power (wattage) is basically a measurement of current flow per unit time. (in this case, 1W=1J/s, and energy (current) is the actual measure of heat/flow. I use wattage because the circuit is not always closed, and we would want to know the power crossing through that node based on the length of time the circuit is closed.

I may be wrong about some of this (I'm a mechanical guy, not electrical), but that is my understanding of it. Yes, I could have taken the measure of current across the coil, but either measurement should suffice for comparisons.

I also have never used a HV atty .... at 6V with my Chuck I use a Joye 510 (from Rocky Mt. Vapor) and Tenergy LifePo 4 batteries .... works like a charm.

I had been using a DSE901 atty for about a week at 3.7v on my Chuck then last night I switched to 6v and the atty blew immediately. I have used new DSE901's for long periods of time at 6v without any issues?

When I first started using 6.0 volts I blew out several regular 510 atomizers. The HV works better but you don't get as much flavor or power. It works better with a regular atomizer at 6.0. After breaking in my mod and keeping my atomizer wet I don't have much trouble.They will not last as long as a HV atomizer will.

But if using a HVatomizer with 6.0 volts you may as well use the 3.7 volt with a regular atomizer. Some people are talking about LR atomizers on a 3.7 volt to get more power but again you have to be careful.

And I understood less than 25%.

That's what I've been thinking since I first saw the HV atties. Which is why I asked about the watts. With the HV atties they increase resistance therefore reducing the current. If this brings down the current to a normal atty, but with a higher voltage then of course the wattage will be higher. But once again current is what creates heat. I'm just trying to understand the fascination with wattage on this site.

You are correct. Increasing current increases heat production. Wattage, or power, is a measurement of energy/time. The power (wattage) is dissipated in to the resistor (atty coil) which converts electrical work to heat. Higher wattage => more work done on coil => more heat => possible blown atty.

I don't know from wattage but i just got a couple HV attys from Ikenvape today and tried 6 volts for the first time. I use a 901 HV atty with RCR123s and compared to the 18650s with a standard atty there's a world of difference. The vapor is warm and really flavorful (my home mixed juice). I would estimate about 30% increase in vapor, so 6 volts with HV atty and 3.7 with standard atty Not the same at all (at least not with the 901).
