Hiya Issac

2.0 rocks. 1.5 is too harsh, kills the flavor.Thats my story and I'm stickin to it :)

Oh ya and short 801s rock them all!

Mine are going on a month, still kickin, but starting to give out on me. Still that is longer then any atty has lasted me ever as I tend to kill them with dark juice. Usually I am lucky to get 2 weeks out of an atty.

Gonna have to rob the penny jar to get a couple more LOL

So ya 2.0 thats the one:)

Haven't tried 1.5 as 2.0 works for me on full power 3.7v mods...

But what about 1.5 on a regulated device (eGo) vs 2.0 on a full powered mod (Lizard)? Are those comparable to one another or is 1.5 even on an eGo overpowering? Curious because I just ordered an eGo for my brother and don't know what direction to point him in wrt LR attys.

Glad you asked :)

1.5 Ohm = 6.4 and 9.1 watts respectively (eG0/3.7V)
2.0 Ohm = 4.8 and 6.8 watts
2.2 Ohm = 4.3 and 6.1 watts

Current draw is what we need to look at IMHO

1.5 Ohm = 2.06 - 2.46A respectively
2 Ohm = 1.55 and 2.05A
2.2 Ohm = 1.4 - 1.64A

Mathematically speaking neither one can be truthfully used on the eGo. That being said a stock 510 atty cannot be used on the eGo as well, neither can a stock atty be used on a reg 510 batt. The resistance is too low. However, when we look at the figures (and why I was waiting for a 2Ohm atty for my eGo) 0.1A increase in stress is not as bad as 0.51A with the 1.5

When talking proprietary batts at $30 a pop here in Canada a single 14500 at 3.7V was more than adequate to do the job, at a fraction of the cost. The difference, it doesnt' vape as an eGo, because of the cone. That being said, even the 14500 was being stressed because...

*** fire series batts have a C rating of 1.5, and unless specified otherwise, the remaining batts are to be considered at 1C. The continuous power rating of a batt can be calculated as:

(mAh/1000)*C or (mAh*C)/1000 for the 14500...

(900/1000)*1.5 = 0.9*1.5 = 1.35A max discharge rate.

Now take the same set up and use 2 x 14500 in parallel

((900+900)/1000)*1.5 = 1.8*1.5 = 2.7A max discharge rate. More than adequate to handle the load.

Even the BDL IMR 14500 at 600mAh with a C rating of 3 is not adequate to handle the load in single cell applications.

(600/1000)*3 = 0.6*3 = 1.8A max discharge rate. Inadequate for both

The IMR 16340 however is more than adequate with a C rating of 8

(550/1000)*8 = 0.55*8= 4.4A max discharge rate.

That being said, the AW RCR123As with their 750mAh are not with their 2C rating, which equates 1.5A max discharge rate.

How stressed is the eGo batt. That is a hard one to fully grasp. Does pulse modulation play a part in reducing stressed produce by the large power demand? The batt is being used at 2 times + it's intended capacity. One thing we do know. Using LRs on the eGo increases recharge frequency, every 3-4 hrs versus every 6-8hrs.

That all being said, yes I use the 2Ohm SLB on my eGo, but not the 1.5

Here's my review of the 2.0 vs 1.5...

YouTube - LR Atty's 2.0ohm vs 1.5ohm.wmv
Pretty much a bang on review Stu.

One thing I have noticed is that that burnt taste dissipates somewhat after the atty has had a chance to season. This is not subjective as an atty that gunks up (seasoned) will produce less heat, therefore a smoother vape.

I have not tried any LRs from anywhere else (besides Drew's), so I cannot categorically say that they are all like that, but I suspect they are. Too much heat... regardless of liquid vaped in my experience and personal opinion.

Since becoming a "technical" vaper, I have found the sweet spot and that is around 8 watts of power, 6 on some more delicate flavours. What I did find however is that Isaac is indeed headed in the right direction. I use the 2Ohm on my eGo as it was bought for that purpose. My previous post explains this.

FWIW wrt the burnt taste of the 1.5 from Drew, it is even apparent using a bottom fed juice box. Constantly blowing out spent liquid helped, but the burnt taste was always lurking around the corner.

On a side note, have you tried the mega eGo carts and attys yet? My opinion can be found in the eGo Social Group. Pretty much what I had surmised from the beginning.

As always I enjoy your candidness and keep on vaping! :toast:

Oops! Actually we're both wrong!
There must've been a change since AW started manufacturing these.
Thank you Chingas!


IMR14500 Specifications :

Nominal Voltage : 3.7V
Capacity : 600mAH
Lowest Discharge Voltage : 2.50V
Standard Charge : CC/CV ( max. charging rate 1.5A )
Cycle Life : > 500 cycles
Max. continuous discharge rate : 4A
Operating Discharge Temperature : -10 - 60 Degree Celsius
Size : 14.07mm ( diameter ) x 48.80mm ( height ) +/- .1mm


Chelsea, Haha Switcher is right. We haven't had them produced...yet ;)

Thank you Everyone for your input on 1.5 vs 2.0! I'm very glad that we're all in agreement with these variations. We too, feel that 1.5 is awfully harsh in usage, batteries and atomizer lives as well. I just wanted to make certain that you guys are enjoying these as much as we are and to confirm that there's no need for change as we nailed a smooth good vape.



Mr Madness, I owe you an email my friend. Thank you for the recommendation! I really hope your bro finds bliss in all the products you got for him.

Confused about something. Switched, you said IMR 14500's have a C rating of 3 but the specs on IkenVape say they are 8 C. Which is correct?

I've corrected my post to add the BDL IMR 14500 has a C rating of 3, whilst I believe there is a typo in other batt specs (referring to the 14500) as the AW IMR 14500 has a 4C rating in actuality 4A which does indeed equate to 8C but the 16340 has the 8C.

Then again with all the "official" wrong info out there, I could very well be wrong again :)

ETA: A Cloud9 vaping post here at ECF does indeed have the AW IMR 14500 listed with an 8C rating, which I do not believe is accurate from my research. But I welcome all corrections especially with the project I am currently working on.

Post modified to compare apples with apples LOL

I would expect the 16340 and 14500 to be pretty close in capacity and drain rate based on their similar volumes, with 14500s having a slight edge due to being slightly larger.
