Got in my GearBest battery order: 4 LK’s, 4 SONY VTC5’s, and 2 GA’s – total of $47 is simply outstanding. Could have spent that on the VTC5’s alone from some other sources.
I did a capacity test on my Opus of 2 of the LK’s (LiitoKala) and got:
5420 mAh
5428 mAh
So seems right in line with what others are getting/have posted. Quick test in my FET+1 (ATtiny25/SIR800DP/dedomed XM-L2 U4 1C) based Convoy L2, and got the following measured at the tail on a clamp meter:
So for internal resistance, seems right in line with the BASEN cells, and also the EFEST 4200’s I’ve measured in the past on the L2. This a somewhat limited test though without testing actual lumens output over time, comparing the cells, so not sure how much it’s worth.
Bottom line is having a 5000+ mAh cell with performance at, or around, the best performance on any cell available is pretty amazing. I’ll be ordering more…
My Opus 2.2 is showing 54 and 50 on the IR quick test with 5130mAh and 5205mAh on the two LiitoKala cells I acquired.
As if I were to trust those cheap electronic devices with regards to precise DC internal resistante readings…
Get a decent multimeter capable of at least reading to mV, and a load with precisely known sufficiently low ohmic resistance to induce a noticeable reading delta on the meter. Do your math then (promediating both initial and final no-load voltage readings in order to dismiss any potential inherent variation in it due to the own discharge process).

Now this is interesting, used Heters in the S70 and Liitokala in the L6
The L6 got much warmer and was brighter.
Since the Heters have buttons I have to remember which one was placed head side and swap each charging.
The Liitokala have no button so I use a magnet. Before charging I put the magnet on the other one so the swapping is easy and requires no remembering.
Decided to do the same after checking the ano of the inside of the S70 and seeing it is good.
And now the S70 is brighter then the L6 and not just a tad but really obvious brighter. It also gets warmer then before
These Liitokala cellsist provide more power, nice!

OPUS test result for IR is not accurate
Agreed, it has been stated on here several times that the OPUS gives higher than true readings.
However as long as you always use that same charger for analysing you can still get get an idea of how your cells are.
I already got like 16 of those, they all have the same good quality: a bit better than Efest 4200
For me its the best high amp 26650 battery atm: and overall the best too, the price is lovely also
P.S
A tip: orther them from GB – they somehow manage to ship them safely to EU- all my orders came very fast so far, declared as kitchen goods, “ srom stuff”( dunno what that means , a quote) or just el. components

Thank you again for updating information on this battery. I have ordered 8 of them from GB too, but they still are on route.
They seem to be a good battery and very much like my favorite Vappower 4200mAh, but at much lower price

I also got several Vappower 4200mAh before, they perform lesser than Efest 4200, they are like Keeppower 4200 actualy, good battery but nothing like Li 26650, the last one realy shines with out BLF fet DD drivers

This is good news the Vappower 4200mAh are older and very hard to find in the U.S.; I have used the Keeppower and the Shockli 4200mAh’s and found them to be good too.
The Li is a bargain.

“…This is the first 26650 I’ve tested that acts like an 18650. Its internal resistance is lower than many of the good 18650’s and it held its voltage well. At 30A/100W pulsed it ran approximately 75% longer, and 0.15V-0.20V higher, than the Basen and Brillipower 4500mAh cells down to 3.2V. It doesn’t match the appearance of any other 26650 I have so I don’t know where this cell came from…”

That $22'99 (Ouch!) I-Joy 40A 4200mAh is just another niche product for preppies with horrible price/performance ratio. Meh…

Excerpt of a report about my findings on internal resistance for these batteries, published last wednesday 2016/09/07 here (e-cigarette-forum):
0K. Just to let you know I've done some smartass battery IR testing on the sixpack. With a LiitoKala Lii-100 charger (pumping close to 1'05A, maybe ≈1'047A, no lab equipment sorry), my standard multimeter and this mV accurate voltmeter: Well, the voltmeter drains 10+mA (I think the eBay ad claimed 11mA). All the cells have shown 23ish mV load/no load deltas (measured with the wires under the flat top button, it shouldn't have any significant impact at this current though). The numbers look pretty good, 22-23mΩ of resistance for these cells. Clearly 20A continuous 26650 cells, with 5+Ah of capacity.
Just remembered…
Cheers

Sorry for bumping this thread, but i had ordered the same liitokala 26650 from aliexpress to use in a flashlight.
The thing is that i need to put 4×26650 bateries in serie.
After the fact of ordering and receiving these batteries i read i cannot put them into series?
Or can i with the help of something like?: Assuming a coin wont work?

Tested the jaxman connector in my Opus and Liitokala charger and did not see resistance go up
http://s.aliexpress.com/qMZJ3aaq
(from AliExpress Android)
Nice thingy
But after testing the inside of my S70 and L6 tube I know the anodization is good and it is not conducting
So I choose magnet for connecting and when charging I put the magnet on the top cell before putting it in the charger so it becomes the bottom one and every charge their position changes (idk if it makes a difference it just feels good to do it like this)
I decided to use non-protected batteries that can be used in series; there are quite a few to choose from that have a positive terminal suitable for vertical series connection.
I use the Liitokala batteries in my single cell 26650 flashlights.

There appears to be a new 26650 champ in the 4200mAh category. Tested by Mooch at the ecig forums:
https://www.e-cigarette-forum.com/forum/threads/ijoy-40a-4200mah-26650-b...
Excerpt from his test report:
“…This is the first 26650 I’ve tested that acts like an 18650. Its internal resistance is lower than many of the good 18650’s and it held its voltage well.

the construction resembles the bak cells.
likely made by bak.

Is that $22.99 per cell
If so that is about the price of 4 Liitokala 26650“s.
Ian
Yep, in fact it is $3.40 higher than the last 4 I just bought & received. I got 4 for $19.59 at GB.

I nice blob of a silver based solder will do better m8, ways ways better
Doesnt need to be silver based solder its not stainless, 60/40 is mustard. Just use some extra flux or scrape the top a bit if its oxidised or dirty

That Jaxman connector works great by the way…….
