Barkuti:
I understand vapcell Dennis , but FaintReality reports twice the internal resistance of an EBL 14500 for his Vapcell 14500. I know his figures are far from real DC resistance values but to me that means his Vapcell 14500 is likely well above 200mΩ of internal resistance. So pretty bad. Being so removing the button top and using a rotary tool with a grinding bit to gently fix the welding remnants is a wise choice.
Using the Xtar Dragon VP4 plus, I got the following results from my current 14500 button tops:
EBL #1 - 54 mohm
EBL #2 - 49 mohm
EBL #3 - 49 mohm
EBL #4 - 54 mohm
Vapcell (gold) - 103 mohm
Efest (2018 purple) - 29 mohm
So although the Xtar may not be 100% accurate, it is more than sufficient to use for comparison sake, which raised a red flag when comparing the Vapcell to the Efest and the cheap eBay EBL batteries.
I would remove button top and re-wrap, but these batteries are for a Sofirn SF14 V2.0 which requires button tops. I may just do it out of curiosity sake…

I just got the 4 wire cell holder today. Still not entirely sure how relevant or useful this information is.

Vapcell fellows please correct the thread's title. “Ture rating for you on flashlight batteries,Buy the battery now to send free zipper case” is wrong for many reasons. I understand the culprit here is a language barrier, so let me help you. “Ture” is a misspelling; “batteries” are just batteries, no need to specify “for flashlights”, “for vaping mods” nor ;-) “for anal hair clippers”; the last part is the worst one, I guess what you want to mean is you send a free zipper case with each pair, don't you? Since you seem to sell your batteries in pairs this is what I would write in the title instead:
Vapcell, true rating for you on batteries. Buy now and get a free zipper case!
Cheers

Well…
After nearly a month of exciting anticipation waiting on the new Vapcell 16340 cells to be delivered the package finally arrived.
Just the package.
An empty box.
Oh, except for some packing material to keep the air inside from being damaged.
Very thoughtful
I need a little help here I think.

Interesting. What country? This is more than coincidence now.
What say ye Vapcell?
Vapcell has apparently sent me replacements too so we will see what happens but if I don’t get them soon then yeah…
Here is another test of the Vapcell 14500 with a 8x7135 driver in the meantime:
I hope you will receive it as soon as possible.
Do you know how to delete previous posts on the forum?Thanks

There is a delete button on each of your posts but not for threads.
You need to ask Admin to delete threads.

I received my Vapcell 16340’s today. I ran a 3 amp discharge test on the icharger from fully charged. I got 638mah at 12 min and 45 secs down to 3v.
Down to 2.75v, I got 726mah at 15 min and 25 secs. This test was done at a constant discharge of 3 amps and there’s no doubt this cell will make 800mah or more at a 1 amp or less discharge.
When I started the test the voltage stayed decently high. It started at 3.7v under the load and fell rapidly to 3.6v where it slowly crept down to 3.5v after about 3 mins. The cell done very well holding around 3.5v for awhile.
We have a new 16340 King, less sag and more capacity .
Thanks Vapcell for improving on these smaller size cells. Great Job :+1: .
sounds like a great option!
and I see on page one:

The new product releases vapcell 16340 batterys with high capacity. Battery with button top , which is
more suitable for flashlight. If you are interested in review or test, please contact me by private letter. and this battery will also sell in Ali-express
I volunteer to do a real world test in my Jetbeam TCR-1, Jetbeam RRT-01, Utorch S1 Mini, Olight Ti S Mini, Novatac, and MecArmy PT-16.
Only One of those lights has built in Low Voltage Shutoff, so Im volunteering to live dangerously, and promise to tell all about it.
I applaud the arrival of this new buttontop INR offering:

Why only button top? Batteries are not manufactured that way. I know the answer and despite I can sort of accept it, it is not of my liking.
If anything a wide button top is better, providing extra contact surface.
Cheers :-)
:+1: or a Raised Flat Top like the VTC5A…
not for me
my lights with physical reverse polarity protection rings, (example Jetbeam RRT-01) dont make contact with flat tops and wide button tops.
Why dont you want to use button top?.. They work in everything, unlike flat and wide tops…

Here are the reasons behind button tops:
Original equipment manufacturer (OEM) concealing.
Lack of reverse polarity protection in devices.
I didn't say I wouldn't use button tops. I do not support the reasons behind, though.
Cheers ^:)
