The two cells do not match completely, but it is not bad for this size battery. The battery can easily deliver 3A, but it pressed above that.

Thanks for the test. Thumbs Up

These are a worthy successor for the discontinued AW 16340 15C. The discharge characteristics are quite different between them but the Vapcell is better at everything except the first couple of seconds.

Thanks for the testing info
I dont understand most of the charts, and I get confused by the visual clutter of so many colored lines

question about this Protection Test:

what does that chart mean? did the battery shut off, or you simply ended the test manually?

It is and therefor the line continues past 7A, one a weaker cell it would “slowly” drop until I stop the test at 2V. A protected cell it will terminate somewhere in the chart.
The slope of the line is one way to calculate internal resistance

Seems like a decent cell. Somebody want to convince Reylight to resurrect this wonderful little 16340 size light from years ago?

Reylight TLF Little Bonny

As I recall, it was a CR123A light, with a boost driver. But a new version with a FET+N+1 driver for Li-Ion could be interesting. Party

EDIT: Actually, forget the FET. Since this cell is good up to 3A, a regulated driver will work just fine. It would be great to have a 7+1 AMC driver with a modern BLF firmware.

EDIT again: According to CREE PCT, a XPL HI can do almost 1100 lumens at just 3A current! Wink

It looks like it did okay with 5A draw, but it faltered at 7A draw. It’s rated for 7A continuous, so maybe you’re right. Maybe he means “struggled”, because that’s what it looks like it did.

Very helpful.
Thank you for the reply, and all your time testing and sharing info

I like the Vapcell 16340 INR because the button top works in all my lights. Even the ones with physical reverse polarity rings around a brass contact button in the head of the light, such as Eagletac and Jetbeam.

The Vapcell 16340 INR even works in my Atom AL, that does not like my Olight and Fenix 16340, that are longer and have flatter button tops.

Im hoping at some point, for a protected version of the Vapcell 16340, since none of those lights have built in Low Voltage Protection.

I use one of these Vapcell 16340 cells in a little Supfire S1 host with BLF-A6 driver and Luxeon V led, all resistances minimised, and get around 1150 lumen at 30 seconds. I think that is close the max that you can get with this little cell and a single led. A XP-L Hi has a considerably higher voltage than the V, and being domeless that makes the XP-L Hi less efficient as well, so I think in direct drive you will end up well under 1000 lumen.

Thank you very much for HKJ’s test.

Battery consistency and power deficiency, hope to be improved in the future

We are doing this.

16340 battery with PCB, we also hope to come out as soon as possible.

At present we can do better 16340, but some battery factories have huge MOQ Tired

The 16340 market is much smaller than the 18350 market.

Hope the future will be good Smile

And Thank users for your support of vapcell Smile

I concur with DavidEF, the 5A discharge curve still looks sort of healthy. However, there is a large difference in internal resistance between the tested specimens. Iffy stuff which speaks bad with regards to product consistency. I also wonder about the button top spot welding quality.

I got this in an eBay email, assume US only for $5 off:

    Code: YUSRAOMY7HW9FPBM. Ends Jun 29, 2019. T&Cs apply.*

Wit this link for qty 2 of these Vapcell 16340's: https://www.ebay.com/i/233242085587?ul_noapp=true

 

If the code works, it's a pair for $5 shipped - great deal. Let me know if it works. I've bought from the eBay seller before - good as long as you know what you are buying.

I just tested the Acebeam TK16 Osram version with these three cells. The new Vapcell 800mah is clearly the king of 16340.

Vapcell 800mah
Output: 1,184 lumens
Tested capacity: 781, 782, 791, 757 mah

Acebeam 550mah
Outpu: 1,190 lumens
Tested capacity: 617 mah

Efest 700mah Red wrapper
Output: 1,112 lumens
Tested capacity: 685 mah

Acebeam for the win, deception free capacity claims. Top lumens, too.

Just to add a quick test of a cell that was bought “in the wild” (nkon.nl) a few weeks ago. I think it is genuine. It performs good in my Acebeam TK16, but are not as brilliant as the samples “provided by Vapcell for review”. I added the included battery of the light for a comparision. They were charged in a Graupner Ultramat 14 plus to 4.2 V, 200 mA and discharged with a Keithley Source Meter 2601 at 3 A to 3 V.

How did you obtain the “provided by Vapcell for review” and can you show comparisons? I also bought the Vapcell 800mah and it seems to match up with HKJ’s review. Also did a bunch of output test and I can comfortably say they are the best high capacity 16340 in existence at the moment.

I was referring to the original test, where the cells were provided, and those work better than the ones you might get when buying them. That goes in line with other overservations in this thread, that mention some inconsistencies. And while I would say, they are even some of the best high drain 16340 (this format seems to be quite rare anyway, so in my case they were the only option even), I guess it is fair to criticise the “optimistic” rating and the inconsistencies.

Ok, but I’m not sure how you compared your cells with HKJ’s results. I would like to see the “differences” you are seeing because for me, at least capacity wise, it is not any worst than HKJ’s test. I’m very happy with the cell.

Reality molds to your wishes, your beliefs so, are you believing right?

I am also sure that at least some or many people actually have no black sheeps, i.e. good cells overall.

Yes, fair it is to criticise the inconsistencies and the (to some point) optimistic rating. The former mostly disqualifies the product for in series operation or battery pack assembly, the latter is the shame of an industry who has been living on deceptive, overrated best case numbers for too long. A battery is a lot more than a freakin' number, most people needs to understand this.

Just compared by eye, the voltage in HKJ’s test is a little bit higher (so, the flashlight would light up a little brighter). I don’t have the means to test it at any higher current. I don’t think I would get a comfortable 7 A discharge out of mine. But as I stated, it works good in the light and I thought the comparision with the Acebeam shows that is a very good performer, and certainly a good cell overall. Which means that I’m also happy with mine.

Well, if you bought enough pieces from different batches, you could see the “differences”. I did so, let me show you some of my results.

I bought more than 30, however I’m a bit tired of verifying their inconsistency…they are still the best 16340’s you can buy though.

I bought 4 pieces of the Vapcell 16340 tested in post #22. You cannot expect 100% consistency. Even the famous Panasonic/Sanyo NCR18650GA I tested varies from 3,375mah to 3,631mah but it is still my all time favorite high capacity 18650 because other high capacities like the Samsung 36G rated at 3,600mah measures between 3,328mah to 3,463mah out of the 5 I bought. It is common for batteries to measure much lower than rated capacity and wide variations between the same batch of cells. There are a few exceptions like the Acebeam 16340, Shockli 5500mah and Vapcell 5500mah that consistently measure a good amount more than the label.

I do not believe the recent batch of Vapcell 16340 I bought is any worse than the batch HKJ tested. Sure there’s inconsistencies just like with any other batteries.
