So what IS high voltage vaping all about? (Everything you've wanted to know plus a bit of electronic theory)

[BiffRocko]

Exactly, which makes it sort of ridiculous to vape at really high voltages, in my opinion.

Now I get it! Great info

Thanks for the post. This is the first physics post my teeny tiny brain has been able to understand!

Agreed. I've decided that all of my battery purchases from this point forward will be the AW LiMN high drain variety. From what I understand, the fact that they store less charge (less mAh) doesn't translate directly to shorter battery life because it can keep up with the current draw. Do I have that right?

Once you cross into 18650 territory the answer is no.

Here's a 2A drain test, notice how the HighDrain (LiMN) quickly pans out (green line at the bottom).

I'll stick to Li-Ions.

Thnx for the info.
Still don't get the point of HV attys though. Increasing resistance means less current. Are they supposed to offset a voltage that's too high?

to me, it's convenience. I use cartomizers that have 3.2 ohms of resistance. They SUCK when using a 3.7 volt device, but at 5.5 volts they are awesome. I make DIY juice, and it's tough to justify using a new cartomizer for each new flavor I make, so I test them with atomizers. If I were to purchase standard atomizers, I would have to lower my supply voltage to get the same power as I do using a cartomizer, because standard atomizers have less resistance. Instead, I use high voltage atomizers, so I don't have to do as much voltage adjusting.

I do have 18650 IMRs now and they don't last nearly as long between charges. However, I'm enjoying the vape I get from them so much more, especially since my daily vape is a dark, cloudy atty killer. Regular and LR 510s couldn't keep up with it, so I switched to Cisco LR 306s. Even with the bridge and wick removed, they still clog up in a matter of a day or two with Li-Ions. The extra heat from the IMRs really helps to keep them from clogging as fast.

I get at least a day from them, usually a day and a half. That is just fine for my needs.

That's a legitimate use if you don't want to mess with VV. Still that seems to be a rather obscure need. Glad it's working out for you though.

That's why I love my VV so much. I have several types of cartos, some suck @ 3.7, so I threw them aside and bought more. But with my VV, they all can vape well! Then its down to the carto construction, and taste factor. And in my case, it changes from day to day. Most days I'm happy with 1.7 ohm resurctors @ 3.5 volts on the provari.

Thanks for the info!! Well written and easily understood!

I've got a decent multimeter tht I use primarily to keep an eye onmy Li-ion batteries. When I use it to measure the resistance of my cartomizers I don't think I a doing it correctly as I a getting a lot of variation. I take one lead and press it securely on the outside of the threads and kind of wedge the second lead inside the hole in the carto. Is this correct?
