5V Issues

[WillieB69]

My new 5V is a monster. It killed an atty and melted the sticker off one of my cartomizers.
Do I need to go to high voltage attys for this thing? The atty I had was a standard atty, not LR and it just died after less than a day's worth of use.

Sounds like your not at 5v. If you have your regulator hooked up backwards it will pass the full voltage instead. Check it with your meter.
I always build my circuits on the bench first and test before applying them to my mods.

Well, I don't have a meter so I'm outta luck there.
I didn't build it since I suck with a soldering iron.

I checked the wiring against various schematics around the forum and everything looks correct though.

I suppose I could write the atomizer off as being bad if it wasn't for the melting cartomizer.

For 5v+ I use HV attys and *knock wood* haven't had a problem frying one. If you are going to dwell in the upper voltage range, I'd get a volt/ohm meter or at least build a volt meter.

Parts are about 10 bucks

....for a few bucks you'll KNOW what you're running

It's probably at 5V. That's considerably more than atties are designed for.

No reason to build that one-trick-pony shown above. This is cheaper and you can also check ohms and continuity.

I use 5v and haven't blown but one atty. I was getting it too hot. I had to do shorter draws, let cool a tad, do it again. I vape heavily. The biggest thing, let the atty cool between hits and don't hit it for longer than 3-5 seconds. 5 seconds is pushing it.

D'oh!

I actually do have one of those in my toolbox.
I never learned how to use it though and can't find the instructions for it.
I bought it with the intention of using it to check resistance on speakers but never got around to actually doing anything with it.

That might be part of my problem too.
I don't let 'em sit long between drags.

If you actually read and comprehended what I wrote, my first suggestion was to get a meter.......

As far as instructions, there are dozens of tutorials on how to use one on YouTube.

 

[WillieB69]

OK.... Thanks for the input, guys.
I'll try and figure out that meter thing and see what it says.

Parallex.... If I promise to put some pants on will you ask your avatar to please quit staring at me?
It's creeping me out.

LOL. And what does your first suggestion have to do with my statement?

 

[WillieB69]

Gentlemen.... Please. Let's all holster our e-peens before someone looses an eye.

I dug out my old multimeter and watched a couple of quick tutorials on the Tube as suggested.

I tested the box and it read 4.97V so that is obviously not the issue. Since that is the case, I went ahead and ordered some HV attys from My Vapor Store to see how those fair up. I didn't figure I would really need HV stuff for this box but apparently I was mistaken.

On a side note, I did a test on my 3.7V box as well. It actually read 3.87V on a battery that had about 3 hours use on it. It's been a good little box.

Just a heads up most of the batteries like the 14500 and such start off at 4.2v at full charge and hit about 3.2 just before they stop pumping and need to be recharged so 3.9 after about 3 hours sounds about right ^^

Willie,
I still use standard atomizers and cartomizers on all of my devices from 3.7 to my 6V Prodigy with no issues. Maybe you just had a bad one. I hate to have you run out and buy extra atomizers you dont need.
Hell I have a standard 510 right now on my VV Tekkeon and I have been vaping it at 7+ volts from time to time without frying the atomizer.
I dont see the need for a higher resistance atomizer unless you are trying to tone down a device like the 6v prodigy.

You need to check for vaping, loaded volts.

Hook your meter inside the box at the atty connector, without an atty and hit the fire button. That may give about 4.2V on a fresh charge. Now install your atty and press the fire button. That will give you the volts that matter, the ones you vape at. Typically it will be at about the batteries nominal voltage, about 3.8V... that's right off the charger.

so 3.9 after about 3 hours sounds about right

It doesn't to me. With a Joye atty and a 14500 at the 3 hour mark vapor production has really started to fall off.

Come on now you should know if he didn't even realize he had a voltmeter he's probably not checking loaded volts and unloaded is what I am referencing which would sound about right at least in my experience as 14500's usually go over 12 hours for me, which would put 3 hours of use at around 3.9 unloaded. I haven't used a joye atty but I've never had vapor dropoff before around 6 hours.

No offense, but that's impossible. But maybe you have some super batteries that do in fact only drop 0.1V per hour.

I can sense the drop off after the first hour. I use 14500's at work, I usually swap them out at the 3 hour mark for fresh. They are OK at 4 hours, but I prefer better than OK.

 

[Nepherael]

Haha yeah the same ones he used when he got almost 3.9 after 3 hours. Granted I thought I was a heavy vaper (go through about 3-5ml a day direct dripping through a top feed tube) but maybe not as bad as I thought.

 

[WillieB69]

Actually, I'm still trying to figure out how to check the loaded volts since the builder seals everything tighter than a Speedo on a fat man.....

 

[Nepherael]

Yeah same here. I don't know hoe to do it without using the one that para posted. Other than just trying to hold wires to the atty and connector and putting the meter in line but I don't have enough hands for something unstable like that
