difference between low and standars resistance atty's, please??????

[Cobra GT]

What is the difference in standard resistance and low resistance atty’s? I see on avidvaper.com you can get standard resistance atty’s from 1.8ohm to 3.0ohm. The low resistance atty’s are from 1.5ohm, 1.8ohm, and 2.8ohm? I thought the low resistance atty’s were low ohms. I know what the HV high voltage atty's are for, just not sure on LR. Am I missing something? Can someone explain this to me or direct me to a link of a post where this information is explained, thanks

Generally, low resistance is 1.5-2.0 give or take a few tenths. Standard is generally 2.4-3.0 give or take. High voltage (or HV), is generally anything above 3.0ohms.

With a LR or Low Resistance atty, most enjoy them around 3.4-4.0v range.

With a Standard, 3.7-5.0v range.

With a HV, 5v+

This is all purely subjective as everyone likes different varieties of a resistance/voltage combination.

Hope this helps at all

The simple answer: The lower the resistance of an atty or carto, the hotter it gets and the warmer the vape. It's an easier way to simulate the higher voltage vaping experience without having a high voltage or variable voltage device.

The technical answer: It's all about the watts. Just like light bulbs, the higher the wattage you can push out of your device, the warmer, more flavourful and harder hitting your vape will be. To increase watts, you do one of two things: Increase the voltage you're shoving into the atty or carto, or decrease the electrical resistance of the atty or carto so more of the battery's power can flow through it at once. For the purposes of vaping, the wattage can be easily figured out with the formula: (volts^2)/ohms. So, let's say you've got a standard eGo. eGos are regulated at about 3.4V. If you use a 2ohm LR atomizer or carto, then 3.4V squared is 11.56, divided by 2 ohms = 5.78 watts. Got a true 3.7V device using 1.5ohm dual coil cartos? 3.7 squared = 13.69 / 1.5 ohms = 9.12 watts.

Yeah, resistance is measured in ohms. Don't know why they list 1.8Ω as both standard and low. The actual readings on them when you put a meter to them vary though. You're not going to get a batch of attys that are all going to read exactly 1.8Ω.

Guess we could always list low resistance atties as low, lower, and lowest.
LR and SR are nothing more than generic terms that anyone can place their own perameters on. Compaired to 100 ohms, every atty out there is low resistance.

Thanks mindfield that is what I needed to know, I don’t know how to slow down that thing. when I put a Fluxomizer on it and hit it the element got cherry red, wtf. The only things that seem to work at 7.4v are like I said the Dripomizers, and both of the ones I have metered at 2.4 to 2.6ohms.

Misinthewoods I tested all of my attys/cartos and non of them are what they are supposed to be. I have a 5pk of Fluxomizers that should be 3.0 to 3.2 and non of them are above 3.0. I don’t have a cheep meter but maybe there meter is better than mine.

Thanks fella’s you guys gave me a better understanding of what I am dealing with. I know there is no regulator or any type of board in this device and I am not sure why it only works on certain atty/cartos. I read in another post that they were having a similar problem and used and extension (510/510) and that solved the problem. that is going to be my next try unless someone has another solution, thanks again.

tj99959 i like your signature that is what i can tell my wife, peace.

 

[tj99959]

Wow, you want a minimum of 4 ohms at 7-1/2 volts!

Try one of these
HR 4.0 ohm 510 Atomizer - Avid Vaper

Even at 4 ohms you are at about 13-1/2 watts

Here is an easy to use calculator

+1

It used to be that anything under 2.5 was LR and that 3.0ish ohms (2.8-3.1?) was standard for Joye 510's. Who knows now. I see sites listing < 2.5 as standard. I give up. As long as they list the ohms it's OK.

Whatever device it is.... if a connector helps... it's probably the center posts not touching. Clean the threads / contacts with ISO (isopropyl alcohol) and pry up the centers GENTLY with a paper clip. Both e-cig battery side and cart/atty.

2 cents.

I have checked the connections and i have tried it with the three attys that are over 4.5 ohms that i have checked. I can pull the two 16340's out and put in a 18650 and it fires right up on all my stuff. I cant understand what the hell is going on with this crazy thing.

 

[AttyPops]

Wow. Frustrating. Some thoughts.

What about either connection issues with the 2 batteries themselves (like pushing too hard on an internal connector and shorting out the connector), or maybe tripping the protection? Are they 3.0 volt or 3.6/3.7 volt batteries???????? It looks like there are 3.7 volt and 3.0 volt 16340's.

7.2 volts at 4.5 ohms is 11.5 watts and 1.6 amps. A bit hot. Maybe someone with 16340 experience will chime in here. If a 510/510 connector solved the issue for another user... it's either connection problem, or maybe the added resistance of the connector tipped the scale. IDK.

If lower ohm stuff isn't working, but higher ohm stuff is... that's usually protection. What's worse is that freshly charged batteries are 4.2 volts for a while, so that's almost 1.87 amps and 15.68 watts. If it turns out to be a protection issue, high-drain batteries will help.

I do know that some stack 3.0 volt batteries (special charger too) for 6 volt vaping. At 4.5 ohms, that's 8 watts and 1.333 amps.... more in the normal range. This is probably what you are after, but IDK if it is what you have (3.0 v... good batteries).

Like I said... maybe someone that uses unregulated HV stuff will chime in here with experience.

Also, I saw several negative reviews of a set of 16340's on a vendor's site saying they cut out.

Remember this too: Watts = voltage * voltage / resistance.

 

[tj99959]

Hate 16340's
How's this for a problem?

I have no plans to use that bat type being as Ultrafire can't even figure out how long they should be.

 

[Mindfield]

That's why you buy Trustfire or AW.

 

[AttyPops]

OK, well.... since I don't use unregulated HV stuff above 5v.... do they make (they must make these!) a 6.5/7 ohm atty or something for stacked 3.6 volts? Or is the target wattage different for these due to coil differences? Assuming he's using 3.6 v volt batteries... what's a good atty to use?

If he's at 3.0 volts and the connections are working/not shorting.... it's probably a bad set of batteries.
