Those are my favorite 16340 cells for high current lights. Even though the graph looks good at 3 amp discharge when you apply that to a flashlight, it’s still under performs. Voltage sag creeps up really quick on these cells even though they are the best 16340 cell for high currents.
From my testing at a 3 amp load the cell is at about 3.5v within seconds of applying the load, then in about 20 to 30 seconds after that its at 3.4v or so. At 3.4v it holds fairly well, dropping voltage gradually for several minutes until it gets to 3.0v. I got a little over 500 mah in 10 1/2 minutes with a 3 amp load at a cut off of 3.0v. Not really what I would call a great cell but it is currently about the best 16340 cell around for now.
Will these become available with a buttontop?
Any chance on a black friday sale for 6,99?
Mine came in today.
What discharge current was that at Djozz?
Hum, will these be “good” to the Led4Power LD-A4 (3A) drivers?
I am thinking of modding a light with that driver and single emitter for a good output and “decent” runtime! If these cells are good for those Amps, I may get some 
Wow it’s legit! Thanks!
Yeah, but at what current. Most 14500 lights now a days draw 2 to 3 amps.
I liked to see a 3 amp test before I replace my Efest 14500’s. I’m still on the fence about these.
I may have to bite the bullet and order a set to test on the icharger.
The discharge current during the test in the Opus is 500mA.
I’d like to see a full test by HKJ up to 15A to see how these hold up in voltage and capacity against the purple Efest 14500 cells at high current (the Vapcell test at 3A already shows a lower voltage).
A hint that these still do pretty alright is the following: I checked the current in my direct drive 14500 zoomie with KW CSLNM1-TG led, two dark purple Efest cells and two Vapcell 1000mAh 14500 cells, right next after each other:
Vapcell1 4.68 A
Efest1 5.11 A
Vapcell2 4.78 A
Efest2 5.07 A
So just 7% less current in a 5A flashlight. If the Vapcell 1000mAh 14500 cell can hold up the capacity at this current remains to be seen (the purple Efest does hold its capacity up to 5A, at 7A the capacity starts dropping)
Sure we do 
The best is high drain combined with high capacity of course but I understand if that is a trade-off.
The best high current 14500 cell is, as far as I know, the purple Efest 650mAh 14500 battery. The high current is really impressive for a small battery. If you can find a battery with that performance and more than 650mAh capacity, or that capacity and even higher current, that would be fantastic.
I drool for one.
I am at your site an have the batteries in my cart. (Vapcell 14500) One thing I am just a bit confused about is: “Are they button top or flat top batteries”? Some of the photos look as if they are flat top others show a button. I need button top cells. Thanks.
Both options are available. Aliexpress gives you the option to choose the one you want. Look under “Color”.
Thanks Pete7874
I missed that simple choice of flat top/button top option. Alibaba does not seem to have all the kinks worked out with the Paypal system. Wanted to use my Paypal line of credit but was not allowed to be used on Alibaba or at the store. Made me grumpy. Could just have used a credit card but did not wish too.
It allows me to use PayPal just fine, alas, there is an additional fee for using PayPal.
I was not clear I could have used a credit card Via Paypal but did not wish to. I wanted to use my Paypal line of credit instead.
Agreed! The Efest 14500 is best at handling high current in the lights I have used them in.
I modded a Ultratac A1 using a Mountain Electronics 17mm boost driver running a XHP50.2 and it draws 6.5 amps from the cell.
Any chance yet of having a suitable shipping method to my country, the Philippines?
I know some AliExpress stores that sell batteries, but cannot ship bare batteries to my country.
So what they did was to bundle cheap generic flashlight and put their battery inside those flashlight — based on my experience some time ago.
What I did: I ordered a couple of 26650 from an AliExpress store, I was not expecting it to arrive (will just dispute if it didn’t arrive).
Then surprisingly, the battery arrived placed inside “generic” flashlight (the flashlight is bad looking, but it worked when I tested it) — so the ‘generic flashlight’ is “free” with the 26650 battery I ordered.
I’m not sure how to do that with your 14500 battery. Maybe can place them inside some cheap AA/14500 flashlight host, then ship your 14500 battery inside the flashlight host.
Grab the PayPal debit card. You can use it just like a normal debit card but it uses only your PayPal balance. It’s free to get one.
What about a powerbank? It’s just a plastic box with a few connectors. You can put more than 1 battery inside If it is enough to workaround that no shipping rules
Wow, these are really 1000mAh !
