As usual the current rating is a bit optimistic, but they do look good with very nice tracking between the cell and constant capacity up to 15A. 20A is also handled, but at 30A the voltage drops.

Conclusion

These cell has very good high current performance for the capacity, but keep the load at 20A or below.

Whatever cell is being wrapped here seems to be a very good one, better than the one in the 4200mAh batteries from Efest and Keeppower, at least at 5A and below.

HKJ, do you have the 5200mAh Vappower in your test queue?

No more Vappower in queue, I only bought two types from Fasttech. Next up is vapcell (I have already started on them) and soon I have a load of Keeppower batteries.

I have tested these… Some months ago… Although my tests cannot go over 5A…
I bought a pair of these and a pair of 5200mAh… As comments on Fasttech suggested that below certain currents was useless the 4200mah… I do not have lights that would take advantage from the more current so I thought 5200 Mah would be a wiser choice… Well in the end I took both… But the 5.2Ah version had IN MY TESTS less precise capacity rating…. IIRC was something near 4.7Ah…but also IIRC the 4200 Ah had also few less capacity… Don’t know why I usually have less capacity in all of my tests

Do you discharge down to 2.5V ?

Thanks for testing!
As of now it seems to be the cell with the least voltage sag in the 5A range. I used your comparator and paired it with all of the usual high drain suspects – this one prevails.

As a result I bought 2 of these from FT. I have by no means the adequate equipment for proper testing (just a humble imax B6) but my quick and dirty test is to take all new cells, put them unter 1A load and measure the voltage with a DMM directly at the cells:
Examples:
Sanyo 2600 FM: 4.09V
Samsung 25R: 4.15V
Tensai 4500: 4.13V
MNKE 3500: 4.15V
Vappower 4200: 4.17V

At least that gives me a hint that I got some good stuff.
So the Vappower 4200 is very good for single cell / single emitter lights in 26650 format like the HD2010 and the UF-F13.

Anyone else pick up some of these? Looks like a few places carry them around $10 each seems pretty great for the performance shown.

Not much excitement over what appears to be one of the best 26650 high drain cells for under 20A?

I’m thinking about picking up some over the Basen deal. Whatch’yall think?

Simplest way is to use their 6-way-comparator and select the 2 cells. compare at 2A, 3A or 5A.
You can even include 4 more cells into the comparison.

Where are these made? China? Nothing written on the battery.

EDIT: I think I just found my answer on a Dealer website:

Vappower IMR 26650 4200 mAh

New Lower Price

These high drain batteries come from a collaboration of engineers from the Canadian battery company, MOLI, and a factory in China. Produced on automated machines.

This is a battery I have been always looking for, it is based on the published data, like the excellent here by review by HKJ.

It is a hard battery to find and at a reasonable price.

IT is hard to find,,,,,,,,,,,the few that I did were a few dollars more than where I got mine on Ebay from a reputable Dealer who i bought batteries before. I got it today w/ my EC60vn coming next week!

Not bad batteries but, as happens with many other random overpriced rewraps, the LiitoKala 26650-50As will smoke these with ease in every aspect. In the history of the 26650 li-ion cells, the Liitos are the messiah of a new age, combining good capacity, good power delivery and great price. 'Nuff said. 

Great review. Smile

I have a group of these batteries and you are correct, but I use these only in my single cell lights. They are a good battery at a good price. I hope to see some test results from HJK. Smile

I would not believe that until HKJ or someone comparable tests them! Wink

It can be clearly seen these cells have an internal resistance of about 26mΩ, easily deduced from the discharge graph.

I've grossly home-made tested the IR of six LiitoKala 26650As: less than 23mΩ. I say grossly because I used a millivolt multimeter but with a load just a tad above 1A, registering a delta of 23mV. 

My figure is consistent with other various results of users in the forum. 

Believe as you like.

Others have had much praise for this battery, and from their view point I have 8 of these batteries.

I find the results provided by Barkuti and others to be very good and helpful. Smile

They are not as good why would you want them!!! lol!

I got 2 for $19.99 w/ free shipping. r-sales on Ebay.

At least $4 cheaper,,, USA dealer,,,free shipping,,,got them in 4 days. I RARELY order from China,,,the wait is NOT worth it, even when you can save a few dollars,,,obviously for these batteries that[saving money] is not even the case!

Thanks for the suggestion. Cool

Sorry, my error.

I only glimpsed at the E-bay and I thought it was the price for just one. Smile

I just received my Acebeam EC50 II, and I notice that the Turbo mode only works with an almost fresh-off-the-charger battery (using the supplied Acebeam 26650). So I started looking at other 26650s, and this Vappower one seems to be one of the best, along with the Efest purple 3D 4200 mAh.

Has anyone seen a voltage graph of the LiitoKala 26650-50A? Is the LiitoKala an IMR? If not, I would expect that its voltage would sag more than the Vappower and Efest IMRs under higher loads.

Thanks Barkuti. If I’m reading the charts correctly, the LiitoKala performs very well, but it looks like the Vappower might maintain its voltage a bit better under heavy load. That’s the characteristic I’m looking for. I’m willing to sacrifice some capacity for longer run-time on turbo.

peteybaby, I do not think you're interpreting the data “correctly”.

The voltage/capacity graphs are nice, but please understand that, when making a comparison with a cell with a noticeably higher capacity, under the same load this means that, for the same runtime, you'll always be in a more “ahead” position of the voltage/capacity curve with the lower cap battery.

In essence, and despite if it seems the LiitoKala 26650A/Bs may drop a tad more voltage in the low-mid range, in practice this is irrelevant, at least by the comments of many experienced users here.

Yet of course, do as you wish.

Oh! If you are really looking for the amps/power, go get some IJOY INR26650 “40A”s. A real 30 amps continuous battery, tested by Mooch.

Thanks again Barkuti, but I was looking at not only those V vs. capacity graphs, but also the graph titled “Acebeam EC50 Gen II, Highest mode, Fan cooled” from user maukka in his review of the Acebeam EC50 Gen II (which is the light that I’m buying the battery for).

http://budgetlightforum.com/node/49555

Unless there are two types of LiitoKala 5000 mAh 26650, his graph shows that the Vappower maintains turbo mode longest.

Otoh, the LiitoKala is cheaper…
