I grabbed 4 of them. I don't plan on pushing them to get the most out of their amp limit, but I like the idea of the safety of the high amp limit. I have drippers that are the same but with different resistance coils in them, and one of the things I have thought about is accidentally putting a lower resistance coil on the AW 18350's than I intend to. These add just that much more safety headroom.
Can someone test them if they get it. I'm only debating it cause I have a kayfun drop kit and waiting for my stingray to come it to match. I haven't used 350 since my provari mini. Smallest I've used on my mechs were 18490. I don't mind varying 4 350 around if they perform good

i'll post here what i think of them once i get em. i ordered on 3/7 so they should be here soon.
Received my 2 18500 and 2 18350 today. Got them on the charger. They look a lot like Sony batts with the raised center on the negative end and similar style on the flat top. I'm guessing Efest is rebranded Sony?
Wrap is very nice, with the amp rating and mAh easy to spot.

Lol waiting for them to restock on the 18500. The price alone for a nice amp is the best I've seen for 18500

good to know. mine (the 350s) are in my mialbox at home, waiting for me
you are not the first ive seen to speculate that these are re-branded sonys. it would be interesting to find out for sure.
if youre willing to go with an 18490, AW IMR is rated for 16.5A. right around the same price as the efest purple 18500s.
Here's my results after testing my new Efests under load. Keep in mind, I just BARELY know what I'm doing. My results are to be taken with a grain of salt.
Testing done with Hcigar M16 Sentinel clone, and inline tank volt meter bought from 101, and an IGO-S built at 1ohm for testing under load. Batteries charged on a Nitecore Intellicharger i4 which tends to overcharge a touch.
Two Efest 10.5 amp rated 700 mAh 18350 (both measured the same). Measured 4.21-4.22 volts unloaded. 3.93-3.94 volts loaded. Also tested an AW 18350 that was charged a few days ago and has been recharded several times which had a little less drop at 3.98 volts under load.
Two Efest 15 amp rated 1000 mAh 18500 (both measured the same). Again 4.21-4.22 unloaded. 4.04 volts loaded. Only 18500 I have to compare it to are used EH IMRs that drop to an embarrassing 3.4-3.5 under load. My Samsung INR18650-20R do around 4.08-4.1 under load.
Overall not bad. I'm curious how the 18500 compares to others. My guess is almost, but not quite, as good as the AW 18490 based on how these compared to my used AW 18350.

i wonder if the batts being brand new have any effect on v-drop. i know that new batteries dont reach their full MAH potential until a few charge-recharge cycles, but im not sure is v-drop changes as the batt "breaks in".
Good point, I'm not sure either. I'll test again in a couple weeks.
I got mine in today also, and here is what I got for voltage drop with my setup.
Mod used- Nemesis clone
Measured voltage drop @ 510 w/ no load- None
Under-load voltage drop tested at positive/negative posts of each atomizer with my digital multi-meter. I measured 3 times in a row with each setup. The Panasonics have been used quite a bit over the last ~6 months. AW's have only been used sparingly over the same time. Efests are brand new.

I ordered mine from e-zigarette-onlineshop.de, but akkuteile.de got them in the day after (a euro cheaper a piece but more expensive shipping). Akkuteile also has a link to the only test of the efests I've seen (performance very similar to aw 18350s).

Here's what I got. Used a chi you clone with replacement slim top cap.
My aw is from 1-2013. Efest purple 18350 brand new.
I thought my aw was 4.2 but it's been charged for a few days and it lost some voltage.
Atomizer is a nimbus clone.
Efest
4.20 charge
4.17 w/o load
3.74 w/ 1 ohm load
Aw
4.13 charge
4.12 w/o load
3.64 w/ 1 ohm load
DMM is a cheap Cen-Tech.

Internal resistance seems to be fairly similar to AW 18350s, going by your tests, which should make these far superior to the red efests. I'll do some (incompetent, sadly) testing when I get mine, and compare to the older efests.

Just bought four of these from 101vapes. I really want them to run in my origin/aqua hybrid as I hate the seams on this device. I run at about 0.7 ohm and these seem to be the answer. Thanks for the data so far and looking for more!
Surprisingly, I received my purple Efest 18350s today. Testing with my Kayfun at 0.82 ohms on my Origin I get a voltage drop 0.42-0.5 (four different batteries, plus I'm very clumsy with my DMM). My red efest 18350s have a voltage drop between 0.65-0.7, my Panasonic 18650PFs around 0.42, and my Sony vtc4s around 0.35. So, the new efest 18350s seem to be on par with "regular" high drain 18650s, superior to the old efest 18350s, and behind the vtc4s. I'm happy with these numbers (though I really need to get a proper inline volt meter so I can take reliable measurements). Now to see how they compare to the old 18350s in battery life.

I bought 2 for my provair mini but forgot minis only use button tops. Oh well got nice batteries for my stealth 350 mechs
Shipping was super fast. Ordered Thur afternoon and got it Saturday, 2 day from Cali to TX with first class is rare lol

I use the efest 18350 reds with no problems at all, although battery life isn't great (par for the course I guess- cause I vape at around 10 watts). My usual vendor is selling these purple "high drain" efests, and they're the same price, so I'm not sure if these are worth buying. Do they have a higher life than the red colour?
