What ohm atty to shoot for

[TENDERFOOT91]

Im using a VMax e cig with a rat tank that I can make my own atty for. Question is what ohm should I try to make , and why. I believe I read that one higher or lower was better for battery life. I just need it in simple English , I'm real new at this stuff. The one I made came out at 3.3 it was four wraps of the wire but should I try and make it lower?
Thank You,
Don.

it depends on how much vapor and throat hit you want. try experamenting i belive that most Genesis Mods and Hybrids only do 1.3 -1.5 and the produce great TH and Vape. check youtube.com. there are some really cool guys who do reviews and who can break it down to you pbusardo - YouTube is one of them. or hit up one of the threads out side of the Newbie Spectrum. Vape Hard or go home

Thanks for the info.

The Vmax isn't like other PVs. It zaps the coil with high voltage in pulses. You could have your voltage set to 3V and it'll be getting 6 volt pulses half the time. 3.something ohms is fine for it. Just turn it up. It's better for the battery to use a higher resistance. A low resistance uses a lot of current and is only good for low voltage devices so that they vape like a higher voltage device. You'll still get plenty of power with 3-4 ohms. A low resistance coil will just burn out faster and drain your battery faster.

Here's why. Forget for a minute you have a Vmax. Say you have a regular variable voltage without pulse width modulation. What you set it on is what it gets.
If you want 9.12 Watts because you like a warm vape you could...

Use 3.7V and a 1.5ohm atomizer.
OR.. You could
Use 5.23V and a 3ohm atomizer.

What's the difference?
The 1.5ohm atty will be drawing 2.47 Amps of current from your battery.
The 3ohm atty will be drawing 1.74 Amps of current.

Both attys are using the same 9.12 Watts.
Watts = heat. They're both cooking juice at the same temperature.

Lower current draw from your battery is always better than high current draw.
Your battery is rated in mah. That's milliamps, or 1/1000 of an amp.
The fewer amps you draw, the less strain is put on your battery and the longer it will live.

3 ohms is ideal for the Vmax or other VV PVs that go to 6 volts. You're very close to that and you'll get all the power, heat and throat hit you'll want.

Hi & Welcome to ECF! I'd say around 3 Ohms is a great place to start. Higher resistance = less battery drain, lower = more drain. On the other hand with a variable volt PV you will presumably adjust the voltage for optimum vaping pleasure with whatever atty/juice combination you're using so I wouldn't worry too much about that... it'll work itself out as needed to get the job done.

My best suggestion is to start about where you are, experiment from there, keep notes as needed & learn everything your new PV can teach you. I just got my 1st vv PV a couple days ago, using a store-bought atty and a couple of Vision Vivi Novas at the moment, and the control the vv gives me is amazing! I hope you can keep it fresh & fun so you don't run out of new things to explore anytime soon.

Best wishes & Happy Vaping!

The problem is that his Vmax is very poorly calibrated. The displayed voltage bears no relationship to the loaded voltage, which bears no relationship to what the vape feels like or the voltage delivered to the coil. The way the Vmax works, they shouldn't even call it voltage. They should just make it a power level indicator because it's really just a relative scale. If the Vmax teaches him his atty burns out or his juice tastes best at 5 volts, it could very well be the case that his juice would taste best or his atty would burn out at 6V on any other PV. Unlike other PVs that don't use PWM, lessons learned on the Vmax are only good on the Vmax. They're not transferrable to other PVs, even other PVs that use PWM.

Thanks for the info, I wanted something that I could rebuild a atty on without too much trouble getting things perfect with ohm but I didn't know what to try to get for battery life. This thing has all the power I will need if I don't try crazy numbers of wraps.
It's a newer one I believe, it defaults back to three volt and reads all the store bought atty correctly with what the boxes say some did have a difference of .5 and it's shiny I don't think Stainless but shiny. They said stainless but I doubt it .all in all I'm happy with it.its keeping me on the right path , day six no smokes and I'm feeling better. My sleep seams different though.
I appreciate all the good advice and information.
Take Care,
Don

Don't get me wrong. There's nothing wrong with your Vmax. It reads resistance fine. It just hits harder than a PV without the kind of electronics (PWM) it has. All PVs with PWM do that. If you like 5 volts at 3ohms, or 8 watts, with a regular non-PWM PV, you'll only need 4.*V with a PWM PV, like the Vmax, to get the same hit. They feel like you're using more voltage than what is on your display. So, you can't really "learn" what voltage is good for what resistance or juice type, except on that particular PV. The info really isn't transferable to anything else.

Regardless of all that, 3.* ohms is a good resistance for a VV. You're right in the slot with the wraps you used. There's no sense in going to 1.5 or 2ohms, unless you enjoy the smell of burnt juice and popping coils.

I didn't take what you were saying wrong. I was just explaining my reasoning. Knowing the Vmax was stronger and I was doing my own atty , I would be able to use whatever ohm I ended up with. Had my supplier had the better one starts with a P I'm not going to try and spell it. I would have had a harder choice. I think I would have still picked this though.
Thanks for all the help. I love the idea of not ever haveing to use a bad or dirty atty. when it gets bad or I change juice I'll just replace it.
Take Care,
Don
