Test/Review of Vappower IMR26650 4200mAh (Green)

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?

Any comparison with the Green Efest IMR 4200mAh batteries ?

dampfakkus.de tested both:

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.

Thank you very much .

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.

Thank you for the link.

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!

Thank you!

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. :-)

Cheers ^:)

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. :slight_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.

Cheers ^:)

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. :slight_smile:

Bang good.com has the VAPPOWER 4200mAh battery for $11.99.

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. :sunglasses:

Sorry, my error.

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