Conclusion
This looks like a good high capacity 14500 cell, it handles the rated 3A current nicely and it do not fall flat if more current is drawn.

Looks to be a great 1 to 2 amp cell with very good capacity.
At 3 amps voltage sag sets in but it still has better capacity and less voltage sag than most 14500’s. Above that and the Efest purple takes over.
Thanks for test data HKJ and all the other data you have contributed.
V11R and V10R Current Mod
Thanks for the test!
I like this new generation of 14500 batteries, I have 4 of these now and they caused renewed interest in my 14500 flashlights. Your comperator shows that up to 2A it performs similar (slightly better) than the Soshine 900mAh 14500, but at 3A it clearly outperforms it.

Thanks HKJ.
It will be nice if they ever catch up to peak 18650’s. I don’t know how it looks internally, but just using external dimensions and simple math, 14500 is about 46% volume of 18650. These “High Capacity” cells are surely better than the older generation cells rated 800mAh or less. But, if it were even close to representative of the volume relative to 18650, then over 1500mAh should be possible. I’m pretty sure we’ll never get that, because the development isn’t worth it for comparatively puny sales.
Thanks to HKJ for doing the testing and sharing it with us here!

Great review as always
I’ve been keeping an eye out for this one as it’s something I’m interested in!
Never say never
again.
The stuffing is already developed. Better small cell technology is anent to convincing a proper OEM into doing it. I am sure many chinese battery OEMs producing good 18650s could do it (Heter, Lishen, BAK, etc) or something pretty close, another thing i$ convincing th€m into doing it.

I wouldn't call that amazing, it's more like there's nothing better. There could be something much better.
Sanyo/Panasonic stopped developing 14500s years ago, probably a decade already. If they were to use their current technology in 14500s we would see 1500+mAh cells with higher discharge rates.
Structurally speaking a 14500 can does not need to be as hull thick as a 18650, so while the useable space argument is valid, it is also invalid to me.

When you consider that it takes so much space in a li-ion cylinder battery for the anode and cathode and the casing, the available space for the electrolyte decrease as the sizes decreases.
If you had a 18500 battery (50mm length) and it takes 8mm for the anode, cathode, button top and CID and a little space left for the connections.
That’s 16% of the battery space length used just to make the battery and 84% left for the electrolyte.
Now if you make a 18250 battery (25mm Length) you still have to have that same 8mm just to make the battery, but how much is left for the electrolyte.
25mm – 8mm = 17mm left for electrolyte. That’s 32% of the battery space length used to just make the battery and 68% for the electrolyte.
18500 84% electrolyte
18250 68% electrolyte
Same thing happens when you start shrinking the diameter. Making a thinner case as Barkuti pointed out or figuring out a shallower way for the anode and cathode might improve more space for the electrolyte.
V11R and V10R Current Mod
The Soshine 14500 900mAh is using the DLG NCM14500-850 cell core, while the Vapcell 14500 1000mAh is using the new generation DLG NCM14500-950 cell core, as shown by my tests below.
Vapcell also offers a button-top version of this cell (they added the top on their own), but the original DLG cell core is cheaper.
I just saw some 2800mAh 14500s advertised on Amazon!
Anyone believe that?
No reviews, yet.
Well, the highest rated (real) 18650 is 3500 mAh. Just scaling that down to 14500 size, with no other considerations taken, the most you could expect is just a bit under 2100 mAh. That’s still a lot more than we’ve ever seen in real life. But 2800 mAh should be impossible.

Fake, Scam what ever you wanna call it, the highest is the vapcell here in this thread at the moment.
Just because it’s on amazon doesn’t mean a thing, here’s another example that surely no one actually believes.
https://www.amazon.com/9800mah-Rechargeable-Flashlight-Electric-Flashlig...
All 8 together might make 9800mah, that only be 1225mah each. That seems more realistic.
V11R and V10R Current Mod
Looks like they just changed the voltage from 1.2 to 3.7 on some NiMh wrappers and left the mAh the same.
I think they are actually lithium 3.6v non-rechargeable, not lithium ion rechargeable and mislabeled when translating from the original language to English.
Then the mAh are in line with other 3.6v lithium primaries.
Nice. Are you willing to briefly share how do you attain those graphs toobadorz? Tools and etc. Thanks.
Shame on you Soshine and Vapcell, yet again rating inflation.

18650 cylinder volume (cm³) is πr² × h = π(0.81) × 6.5 = ≈16.5405cm³
14500 cylinder volume (cm³) is πr² × h = π(0.49) × 5.0 = ≈7.6969cm³
This means 14500 is 100 × (7.6969/16.5405) = 46.5337% the volume of 18650.
3500 × ≈0.465337 = ≈1628.68

That’s a little higher than what actually can be achieved.
Consider that the anode and cathode take up a percentage of the cell, the smaller the cell the higher the percentage of volume the anode and cathode take up.
If we say in a 18650 the anode and cathode take up 6.5mm (makes the math easier) that’s 10 % of the total volume, 90% left for electrolyte.
For a 18350 cell the anode and cathode is the same 6.5mm and that’s 20% of the total volume, that just leaves 80% of the cell volume left for electrolyte.
If you made a cell 18065 with the same 6.5mm anode and cathode there would be no space left for electrolyte, yet the cell still has volume.

Can understand moderator007, I could also consider the cell can thickness and bla bla bla. To me, and you know, these are just excuses. Everything can be properly scaled up or down and counter volume losses.

I used to test the batteries I bought with EBD-A20H (an electronic load for up to 20A discharge) and a 30A version BF-2A (a 4-wire battery fixture).
I purchased 4 of these from Vapcell direct off aliexpress (in their 11.11 sale) and after receiving them last week one died on the first use!
They all came at ~3.62v and took an initial charge but then the first cycle in a light I got a low voltage warning abnormally soon and saw it was at 3v after just a day of lite usage so I took it out and it’s self discharged to 90mv in just 3 days time.
The other 3 seem to be maintaining their voltage and the 2 others I’ve tried so far seem to work fine.
Should I chalk it up to cheap China sourced cells or ask for a replacement? The other pair of them I’ve been running are from liionwholesale and they’re button tops (these aliexpress ones are flat top) so I was a little concerned from the get-go…
RIP SPC Joey Riley, KIA 11/24/14. Now I am become death, the destroyer of worlds.
You should pm Vapcell_Dennis here. He is always very helpful. Always report problems to the manufacturers to help them fix problems and improve otherwise they would not be aware of it.
I need replacing battery 14500 for sonicare.
What to use
Vapcell ICR14500 1000mAh – 3A
or
Sanyo UR14500P 800mAh – 5A
What you sugest me?
svicar1, the Vapcell ICR14500 1000mAh (950mAh manufacturer rating) is overall better than the Sanyo UR14500P without a doubt. The UR14500P isn't a 5 A cell, but more like 3C or ≈2.4 A tops.
The choice is clear, imho.

And Shockli is even marginally better.
I don't think there really is any actual difference (besides cell grade or batch and etc.), both Shockli and Vapcell buy their 14500 “1000 mAh” cells from the same OEM as far as I understand (Heter cell; the manufacturer rating is 950 mAh, btw).

I’ve seen it a few times that Shockli cell measured by HKJ performs slightly better than Vapcell one.
I used to assume that they try to get better grades…but now that you made me think about it I wonder whether they just send cherry-picked cells to HKJ. Or whether it’s just a random effect caused by small sample size.
As to this cell – I tried to find some more information on Heter 14500. It is not present on hetercell.com. Could you please share some more pointers?
I doubt they are the same cell. The Vapcell measures higher capacity but noticeably less output in FET lights. So if you are using FET lights, then the Shockli 14500 is better for max output. But for most 14500 lights, there will not be any difference in output and Vapcell has the advantage of more capacity. Both are the best 14500 you can get.

I do not think battery OEMs may be willing to share their latest product advancements to the general public in their websites, that may require some digging. But maybe I could gather some info from a known source…
Despite certain manufacturers of li-ion cells may share one of the most characteristic “OEM traits” of cylindrical cells, the top pole shape or geometry, among big OEMs this is pretty uncommon. In some cases a closer look reveals subtle differences, this is what happens with the newer triple leg top of LG Chem which is very close to that of Samsung SDI, but not quite the same. Heter also uses a triple leg/lobe top, but with a quite wide leg. I've seen it on many other non-usual cell formats, like 16340s and 16500s.

Agreed. Comparing the discharge curves of the shockli and vapcell they are obviously different cells; different shapes and IRs.
I just received a shockli 1000mah 14500 ordered from their AliExpress store to upgrade my edc light capacity. However, the windyfire 600mah 14500 is still the highest performance 14500 as far as I know (lowest IR).
