Choosing a LR atomizer?

[Vidi]

We had a meet up last week at which I noticed that others were putting out CLOUDs of vapor where as I was putting out puffs of vapor. Turns out they all had LR atomizers. One of them gave me a LR atomizer that simply rocked ( he got it from a coop with China ) but last night it died. and I mean died, it just wont do anything.

So today Im shopping for more. I'm thinking 4 should be enough for now.

Unfortunately I read that with my eGo batteries, I have to stay above 2.0 ohms as 1.5 ohm LR attys can kill the batteries.

If this is true, which LR attys should I go with? Where do you purchase yours from?

Also, there appears to be different kinds. Joye, SLR, Cisco...which do you prefer? Which seems to work best with eGo 650/900 batteries?

I appreciate any help/info on this as I am now moving into more advanced vaper territory here.

I prefer the Cisco LR510 attys, but they are rather expensive - $8.95. I also like the LR510 attys from EastMall and they sell for $3.00 ea. in packs of 5.

Using atomizers below 2.0 ohms will definately shorten the life of joye ego batteries and other brands that are similiar like the RIVA, Vgo and others. I have even toasted several Hello 016 batteries with them as well and they have a 1300mAh rating. The problem is the discharge rate of most li-ion batteries. Typical chinese e-cig batteries (especially the ego and knockoffs) are simply not capable of sustaining the discharge rate demanded by a LR atomizer. They may work for short periods but they will eventually fail. I have not had any fail with any serious safety effects but i did have a couple completely melt the battery buttons when they ran away. IMO, the real issue is not which atomizer brand is better or in the case of the Cisco ones, specifications rather than brand, but with the characteristics that are presented when using a LR atomizer at 3.2 - 3.7 volts. True Ego batteries don't produce a working load of 3.7 volts since they oscillate between ~3.2v and ~3.7v so they don't really produce the same performance as a HV mod running the same atty with a voltage closer to 3.7v, and even then only when the battery is fully charged. Almost any brand new 2.3-2.5 ohm atty will produce great results for the first 30-40ml of juice at true 3.7v. What most people say they get from a LR atty is better TH, personally i find it more throat burn than TH. LR attys produce what i consider flavorless and harsh vapor but theres a lid to fit every pot as they say. If you are looking for a chinese model that will handle 1.5ohm attys and last a long time, good luck. If you want better performance, flavor, and TH I would recommend looking at some of the HV mods and staying with higher ohm attys. The batteries are cheaper although they do require an external charger. The higher ohm atomizers should also last longer. The new high-drain IMR batteries being adopted by most of the mods are much more capable of handling the increased current demands and still lasting a good while. The sacrifice to get more power (watts) is always going to be something... either short battery life using smaller 3.7v ones or a much larger device when using larger batteries and/or multiple batteries. There are some brand new devices available now that can produce variable voltages which allow you to "tune" the output for just about any atomizer to your liking. The Provari by Provape looks promising and produces higher voltage from a single IMR battery. A lot of people like the buzz from notcigs as well. The Prodigy V3 by Puresmoker, Xhaler by Nhaler, SB by Altsmoke and others can produce higher voltage but require stacking batteries.. On specific atomizers I will say that the LR attys from Eastmall are harder to kill than many others as David changed the design by altering the number of windings in the coil and using better ni-chrome wire but i find their performance diminishes very quickly (as i found with almost all LR attys). I was going thru 2-3 a week to get any real performance. Ikenvape attys also perform well. My overall preverence is using the cheap slb 510 attys with about 3.4ohms at about 5.7v. They produce tons of vapor, are cheap (google dse-510 atomizer) and you can find them for about 5 buck apiece. Again, IMO there simply is no substitute for increased voltage.

 

[Vidi]

So ( and forgive my noobiness here the whole voltage thing has me stumped ) my eGo batteries are putting out around 3.2 - 3.7 volts. A LR atomizer takes that down to 1.5 which produces more TH, more throat burn and more vapor.

In order to really take advantage of the LR atty, I need a mod not the ego?

Is there a list of the various mods and what their agreed upon ( I realize thats asking alot ) performance qualities might be?

MrGrimme,

The eGo battery Cycles between 3.2 and 3.7 volts. The LR doesn't take it down to 1.5. The LR atty is about 1.5 ohms. The eGo battery will not support the current required by the lower resistance atty. To support a LR atty, U need a true 3.7v device, IE a mod using a stock Li-ion battery, but still to support the higher current U need a larger battery like the 18650 or a high drain in anything less.

I use a rough stack with a 18350 battery or with a 18650 battery with the extension tube (Maxi Rough Stack) and it works great.

Hey Dude! Glad to hear you are digging LR's...just wish I had been the one who turned you onto them last weekend. I'm selfish like that

At any rate, Best e-Cig Mod List | e-Cig Mods Database will give you a list of most all known commercially available ecig mods. Excellent resource!

As for LR's themselves...you can run a Cisco 1.5 ohm LR on an eGo, but you are correct that doing so will probably shorten the life of your eGo batts. That being said, it's still an awesome vape. Same goes for the EastMall LR 510's.

If you're looking for a 2.0ohm LR, a couple of places that sell them. If I recall, the Bauway LR's from Madvapes come out to about 2.0 ohm. Welcome to IkenVape also sells 2.0 ohm attys...and these are definitely 2.0 ohm.

Hit me up if you have more Q's.

I'm sorry... but this is simply not true. There are other threads on this subject, and I really don't feel like repeating all of the technical details every time I hear this claim..... but bottom line: somebody got it in their head that the eGo class batteries can't handle the LR atties. Others people repeated it, and now it has become urban legend. But at the end of the day it is still not true.

Nope, the Bauway's from Madvapes are nominally about 1.7 Ohm.. with a +/-.3 Ohms spread. BUT, you got to keep an eye on those atties. The have a bad habit of developing coil-shorts which will drop the resistance into the 1.0 Ohm range. And due to a design flaw in the protection circuit on the eGo/Riva class batteries, that can/will cause the MOSFET to fail (not the cell).

What about the SLB's? I know I got an LR from MadVapes a while back that was marked as LR but ran at 2.0 ohm. Then again, maybe I am incorrect. As always, I will yield to your knowledge of the electronic side of vaping, Sir Scottbee!

Hoogie threw in a couple of the SLB's with my Bauway order quite a few months ago. In that specific case, those atties measured in at about 2.0 Ohms. BUT... they are listed as 1.7 Ohm devices on his web site.

I knew I wasn't completely crazy!

In terms of LR atties the best two varieties IMO are:

1. The Cisco LR's - Excellent lifespan, great flavor, great vapor - Every Cisco (510 or 306) that I have metered out has come to 1.4 ohm. That could be my meter, but I have a feeling it's not
2. Eastmall - These consistently meter at 1.5ohm for me - The consistency and quality of the NiChrome wire are not as high as that of the Cisco attys, and thus they do not produce as warm of a vapor

 

[akcrabslayer]

Cisco atty's all the way and my son has been using these 306 Lr atty's for eight months on the same two e-go batteries,and my wife and i switched to these atty's two months ago using e-gos and have not had any problems.

 

[Scottbee]

I find that I can't recommend any specific LR atty any more. Not because I haven't had/found any good ones.. but because the manufacturers have such crappy quality control and have a bad habit of "losing their secret formula" from batch to batch!

I try almost every new LR 510 atty that comes out. I'll get some good ones..... then order another batch from the same supplier/manufacturer and they'll be completely different in both construction and performance. It is really disheartening!

Sometimes urban legends are based in some part on facts. None of us can argue with Ohm's law or that the batteries should handle it if the circuitry in the ego batts performs as specified and all aspects of every battery performs to specs as well, but i can honestly say that i have 8 of them dead in a drawer after only about a month of using 1.5ohm LR's on each of them. 4 were true Joye's and 2 were EM Rivas and 2 Hello 016s. Like i said in my post, the only ones i had fail with any kind of fireworks were the Hello 016 batteries. Both ran away and completely melted the circuitry and buttons. They got so hot i couldn't hold them long enough to unscrew the atty. I did check the atty for short after both run aways and they were fine and i went on to use them on other batts without incident. The 016 batts did however produce great results for their short life though ;-). All the ego and rivas failed in much less dramatic fashion, they either wouldn't go into charge mode anymore or they simply wouldn't hold a charge that lasted for more than about 20 minutes and as far as i am concerned, that's a failure on a month old 650mAh battery. Probably not a cell failure but still a battery failure. If handling the load means will they fire and produce vapor for x amount of time then i agree that they will do that. I also fully agree that a "proper" or ideal 1.5 ohm load lasting the brief 3-5 seconds that most people inhale should not produce a drastic decrease in cell life if the management circuitry is working properly, even though the cells of that chemistry and capacity should not be able to provide enough current to produce the wattage desired. I can also agree that given the complete inconsistency of the specs and quality of atomizers comming from China that shorts and faults in the atomizers are possibly (likely) the cause but that's the practicality of the situation, dealing with the actual products and not ideal formulas. If the only parts of the circuit were the cell and the coil then it would be a lot easier to negate claims that these batteries do fail under low resistance loads. What i can say for certain is that 8 batts of that design died quick (quicker?) deaths after consistant 1.5ohm loads while other i have never exposed to those conditions are still living nice full lives. FWIW.

I started using LRs with my REO Mini back when I first got it. I've found that they don't last nearly as long and are always on the fritz, especially with a bottom feeding mod like the reo mini. It's always a case of too little or too much liquid, and it goes from almost gurgling to glowing red hot in about 3 vapes.

I just ordered some of the new LR Atties they have up on MadVapes to try them out. I was not impressed with the Bauway ones I had ordered before. If I can't find something that isn't better than 50/50 hit or miss, I'm definitely going to trade the throat hit of a LR for the relative ease of using regular old 510 atties.

 

[BlackMetalBuick]

I just got the Cisco 306 LR for my Inferno. Liking it so far. Lots of vapor. I'm still getting over a cold so I can't comment on if the flavor is any stronger. Thankfully Volcano has a 12 month warranty on their batteries, and they themselves sell these LR attys, so I anticipate no problems if my battery does decide to die.

After almost a year working with the eGo/Tornado and Riva batteries (my own, and the returned batteries from one of the larger Midwest suppliers) I have only seen one or two failures that can actually be attributed to the demise of the Li-ion cell. And that's out of a pretty large sample size and a heck or a lot of use. The rest either had a popped MOSFET, or an "iffy" connection to the cell. In my personal collection, all of them have gone beyond 100 charge/discharge cycles, most beyond 200.

YMMV. I'm just telling you what I've seen and what I've actually tested.

Pretty much right on with what i was trying to say (in my usual long-winded way). I doubt any of them were actually cell failures, except in the case of the 016s perhaps. I started using the original Ego when Mik first announced it and had great service (albeit typical performance) from them. I still box up an older but still functional one every now and then to give away to someone to try. I am with you that the majority of "failures" are most likely the poor tolerance of the other electrical components or poor quality.

What is MOSFET?

IIRC... Metal Oxide Semiconductor Field Effect Transistor..... or something like that.

In the commercially available "traditional" PV's, it is the transistor "switch" that actually routes the current to the atomizer. The small tactile switches, or vacuum/sound switches used in autos can't directly handle the requisite current for firing an atty. So circuitry is required, and the "last stage" in that circuit is usually the MOSFET. And when the current demands exceed the capabilities of said MOSFET, it fails. Sometimes they fail in the "on" condition, sometimes they fail in the "off" condition. Sometimes they fail and just become a smoldering little blob of plastic, silicon, charcoal, and little shreds of metal.
