Are IMR really that good? I can't find myself liking them...

I agree. I was just looking at them performance wise... especially when I see people refering to them as "high draw, tons of power, etc" I was thinking like... arg... I wouldn't put those in a plane... but safety wise, no doubt they must be a lot better than our average 50C lipo that will ignite if you look at them the wrong way
No harm done. Regards

I just thank the gods we're not stuffing our tubes with Hobby King Turnigy lipos, that's when things could really go sideways.

LOL, my flight packs aren't Turnigy, but I didn't think they were that bad. OTOH I don't vape my flight packs. I wonder what's in the MVP.
Too technical for me, but I hope you get to the bottom of it. I bought four AW18350s from RTD Vapors and a xtar VP1 charger. They have worked fantastic for a year now.
tony;
seems ryedan and baditude already have you covered.
be sure to post pics of your AW cells on candlepower forums and ask andrew himself if they're legitimate or phonies.
do some research on those particular efest batteries. the critics/gurus tend to sway from them because of mislabeling and inflating the stats on known cells. bad practices when near your face...
personally, i consider the safest battery to be one that's used in moderation in a safe manner. i'd consider a 2500mah 70c lipo safer to pull 40 amp 10 second bursts up to my mouth than any imr or hybrid i've seen on the market. but that's apparently just me. though, there is that rare occasion you get an unannounced hard short to account for.
most importantly, consider the source and ask before your future purchases until you're familiar enough with the products and the nuances (such as spotting a fake AW cell and finding legitimate retailers that carry them for example) so that you get the best products for your money.
p.s. you can get samsung 25R cells for a similar price as those efest batteries. they're great performers.

I like lipolice batts (65C continuous (325A), 100C max(500A))... something like that coupled with a low ohm atomizer would sky rocket the e-liquid, coil, wick, atomizer and probably the person holding the device... and that under normal operating conditions
I'll let you know when I make further tests. The el-cheapo charger should arrive tomorrow morning.

I saw those comments mostly about the 18650 (like 2600mAh or something like that). The 18350 don't seem overrated at 700mAh... actually they are quite lower than some other fire brands stating 800 and 900mAh...
Only times I had a battery vent or swell on me was in heli applications, as long you don't overcharge them and don't discharge them over their rated power/voltage, it is extremely rare to have a blow out (I'm talking about lipos)... Well... you could stick a fork in a lipo and it would a nice show but thats physical abuse unless you are disposing them and in that case they should be dead with the prior week length salt bath.
I guess the 18XXX line will be much safer than that.
Cheers

Hi again.
My "el cheapo" charger arrived (finally). Its an Efest Soda something. pretty basic but hey... it was made to charge those 18350.
Ok, so I charged all my batteries on it ( 2 x aw imr 18350 (uncertain if original or fakes) and two efest V2 18350 purple batts.
Final "charged" voltages are:
AW1: 4.186v
AW2: 4.174V
Efest1: 4.158V
Efest2: 4.167V
So, all in all, I'm getting exactly the same values as I did previously with my old and unfit ALC. I got all those batts from 3 different stores... one in Ireland, two in Spain and one in Portugal. I also tried a cheaper multimeter but besides rounding up the values a bit, it never actually read 4.20v
Don't know what to think. Those values do match my theory that those batts don't hold 4.2V for more than a few minutes off the charger but hey... its still under a 0.05V deviation in all cases. Obviously nowhere near the precision of a Li-po holding 4.340V for hours/days but like mentioned before... safety over performance. They are also a fraction price wise of a top dog li-po so one can't expect the same results.
Kinda reminds me of an old local saying: "An one eyed man is king among blind people"
Oh well... at least I had some fun measuring this stuff.
Best regards

Aside from the RC guys like some here in this thread, most vapers use chargers that cost under $30. They take the battery to 4.2v and there's a quick drop from 4.2v to 4.1v when it gets put into a mod and a battery voltage check is performed. I don't know how many verify the voltage, but I do it every time. My Provari mod drops the second digit after the decimal, so 4.1v might really be 4.195v. I'm just checking to see that it reached normal voltage.
LiPo doesn't get much press around here. lMR is king and some mech vapers use L-ion batts with fuse protection and/or sacrificial springs. If we get 8 or 10 hours of vaping from a battery, we are happy. Ecig discharge rate probably isn't anything close to what RC stress puts the batteries under, so we look for vape time, not necessarily voltage on a curve under heavy loading. We can crank the voltage in a variable mod to offset cell discharge, so time to 3.4v or 3.5v is how we judge a battery's performance and charge life.
The link below takes you to a long list of batteries that were tested and the results made available to vapers. Naturally, there are batteries in the list that I wouldn't put in my Provari even knowing that they tested superior. Anything with a name that ends in FIRE probably will at some point. There are others, but we like AW, Panasonic, Sony, Efest, and a few others for vaping. lMR is what I choose when it's time to buy new ones.
Battery test-review 18650 summary
I guess my point is that vapers use batteries more like a high end flashlight and not nearly as stressfully as an RC model. Granted, there are people around here that claim to vape at 20 and 30 amps. I wouldn't stand next to them at a vape meet without a clear egress path. That's just me. I"m not into stressing batteries beyond a few amps. Vape time is my goal.
It's a different world with vapers and you will find a wide range of preferences in the vaping community.

Hi.
Yes I realize that know. I just thought it was a contradiction seeing all the hype on some threads about super batt A versus hyper batt B...
I was used to other kind of stuff but, like you say, vapers have to deal with other priority needs (like safety). I'm sure that in time batteries in this world will become better and better while maintaining higher safety standards than in other applications. The tecnology is out there... somebody just needs to make them safer for vaper use.
Thx for the link. Really interesting
Regards
Tony

From that list of batteries in that test comparison, I only recognized the AW IMR and ICR batteries, and the dreaded Trustfire and Ultrafire batteries. The others in the list are not commonly used in vaping, probably because the tests were done for a flashlight forum. I didn't see a publishing date of the tests.The link below takes you to a long list of batteries that were tested and the results made available to vapers.

With sub-ohming becoming more and more popular (even I have joined the crowd), 20 - 30 amp IMR/hybrid batteries are in high demand.
I see the same thing right off the charger. An almost instant drop to 4.1something and then hours until it reads 3.7v ... and more hours until it reads 3.5v. Then, I swap out and charge again. I'm aiming for maximum battery life with little stressing. I rotate 6 18650s so they get some rest time. All four of my AW 18650s are delivering satisfactory vape time after over two years of swapping in and out of my mods. The two Efest 18650s are edging out the AWs slightly, but they are only a few months old.

Thanks for the info
I think that 4 batts will be enough for now. I'm still using my mini zmax mostly at home as I prefer the lighter Itaste V3.0 for vaping outside during worktime. Its more manageable than holding a potencial heavy weapon in your hand. Its also much easier to lock the itaste than the zMax to put it fast in your pocket without the risk of firing it acidentally.
All in all I'm happy with my setup. Now I only need to find the right all day liquid to build up some stock. I've gotten more dissapointments than happiness with that over the last few days... Oh well, I will eventually find something.

Hello Tony, Sorry for being in the late freight with this but Yes, As you suspected The iTasteVV (V3.0) contains a 800mAh Polymer Li-ion Battery. The MVP from Innokin contains a 2600mah Polymer Li-ion Battery.

don't forget the LG HE2 and the samsung R series (20R and 25R). some of the tech geeks and builders... especially ones that sub-ohm tend to favor them. i'll take the 25R over the vtc5 @ 11 amps every day of the week, myself.
i would stand as close as i could get. them guys usually put out a ton of great smelling vapor not muddied by lots of nic.
plus, a vape is a very short length of time. it puts a lot less stress on the batteries than one would think given the overall tone on the subject on this site.- Status
