Is it dangerous using 2.5+ ohms atomizers with a 18350 battery?

[chadmo]

I recently purchased a sigelei Mini Zmax mod, Efest 18350 3.7v 800mah batteries, a few rebuildable atomizers, and various 24-32 gauge resistance wires.

I want to make atomizers that produce very little vapor, and I plan to vape on the mods 3.0V setting. There is lots of safety information out there about the lowest ohms that can be used with 18350 batteries, but little to no information about high ohms safety.

What is the highest ohms that could be safely used at 3.0 volts with a 18350 battery?


Thank you in advance for your replies,
Chad.

Since you will be using the 3 volt setting, you should be completely fine since there will not be a lot of amperage being drawn from that battery. I'm not sure about the highest ohms that can be used, since it's usually about how low of resistance you can build safely within the limits of a battery (for me anyway since I sub-ohm). I'm not too familiar with high-ohm vaping, but I assume you should be fine with a 2.5 ohm build.

Check your specs out on your Mini Zmax mod and it should show you the minimum/maximum ohm limits for your device.

Would you see any safety issues with 3.0 - 3.5 ohm builds using 3V?

I checked its instruction manual and it had no information about ohms. And online specs only mentioned a error code for the units display showing "Low Load= low atomizer resistance (less than 1.2Ohm)"

Thanks for the reply,
Chad.

Here's a chart that might help. Most vv/vm devices will have an upper limit on ohms that they'll work with, just as they have a lower limit.
2.5 to 3 ohms should be fine.

You will be very safe. It is low ohms you have to worry about.

At 3v setting you should be able to go as low as 2.2ohms.

At 2.4 to 6.5ohms, you'll only be vaping at approx. 3.75-1.8 watts at 3.0v battery setting. That's pretty darn "cool"! Your battery will last longer, you'll be providing less heat at your coil, and you will surely use less e-liquid and probably not have many dry hits

Hope you'll be able to taste your eliquid

Most people vape about 6 watts minimum these days.

I have a few coils for kangers that read at 2.4 ohms I've run those at 3 v on my provari mini with no issues.

 

[Bunnykiller]

there wont be any issues going with hi ohms except for one thing.... flavor and vapor production will be minimal.... very minimal... but I think you said thats what you are going for

Thank you for your replies.

Here are my (initial) results. I used a Phoenix rebuildable atomizer that came pre-coiled at around 2? ohm. When I went to take off the coil some of the wire loops came off the +/- posts, and I had extra wire and both ends were still attached. So I re-tightened the +/- and tested ohms, and it was 2.7 ohms. I had extra wire to the coils so I raised up the coil, put the strings in the base, stuffed the base with cotton, and then filled with e-juice.

First I had to make the air hole smaller. And at 3 volts the vapor was heavy and not great. But at 3.3 volts the vapor level is low, the taste was acceptable, and I can feel the nicotine.

I'm about to rip off this coil and do more experimentation. But I can say this now "Rebuildable atomizers are great!!!"

May I ask, what your movation is to have as high of Ohms possible , very little vapor, and very little taste is? What and why exactly are you trying to achieve? (besides little vapor and flavor )? I'm trying to understand WHY? Why would you want this? Thanks. I just don't understand What you would gain from this?

There's no safety problem with using low voltage and high ohms. The question is whether it would work.

You don't just decide what voltage you feel like vaping at; you adjust the voltage to suit the coil

At higher voltage the vapour level should increase; what you saw happen was some variation from a fresh coil and wick; you probably didn't dryburn the coil either.

I don't know how the OP will answer, but I cut almost every eliquid I don't make myself in 1/2 (with VG). I am a person who finds a lot of flavor to be offensive. I like a nice cool mellow vape.

Most of the time I vape unflavored. I like it, but it also keeps my coils clean, it's cheaper, and it got me off the "flavor chasing" and vapers tongue (law of diminishing returns essentially).

I have an older Joyetech 18350 mod that runs at 3.4 volts. I use 1.8 ohm coils. (6.4 watts) I occasionally use 1.5 ohm coil which are still only 7.7 watts.

A 2.4 ohm coil would be 4.8 watts. This is well within any safety range.

Mainly for health reasons. I vape very often and I would like to take in the least amount of vapor possible. I also read that vaping at high voltages creates dangerous chemicals, and I assumed higher ohm's could be good for low voltages.

I also think vaping may make me cough sometimes, and perhaps sometimes even gives me a sore throat. And I thought low vapor output might help those problems.


When I first started vaping I always looked for the way to get the most vapor, but because of the reasons above I'm starting to look for lower vapor. Plus Racehorse's response in this thread has me thinking I could save some money by using less ejuice.

Have a nice day/night,
Chad.

What is dryburn-ing the coil?

I did use a cigarette lighter to heat the wire before coiling, and then I wiped the wire clean. Is there something I did not do?

Thanks,
Chad.

With 2.5 ohm you will be safe at any setting of your mod (including max setting - but you can burn your wicks). With 2.5 ohm do not limit yourself to min setting, you can try to go higher to find the best spot for you (it is possible at min settings you will have next to nothing of vapor).

Until my iStick 50 gets here I'm using an old school mech mod running 6V with 3 ohm coils. trust me, you have no safety issues running half of that voltage at the same resistance. It may not produce enough heat to melt an ice cube, but safety issues? Nah. Three ohms at 3 volts is a very weak vape indeed, (3v at 3 ohms is only 3 watts) but that's what you asked for
