Test/review of LiitoKala INR26650-50A 5000mAh (Cyan)

Nice info, toobadorz. That 5500mAh cell looks impressive. It has a bit higher IR from looking at the discharge curve, but not too bad.

Thanks for the review HKJ.

I bought four of these last summer from GB.

They still have them although they are to restock on Feb 8 - tomorrow. However and from the actual pictures on GB, they look exactly like the supposedly fake mentioned above…

Mine look genuine but don’t have the exact same marking above the bar code. It reads “+ 3.6V 18.0Wh -” (no F3) and below it differs in the VBxxxxx number. I remember testing them with the my BTC 3100 and they all ranked above 5Ah.

One thing that’s worth mentioning is that the LiitoKala logo is not printed on the wrapping like the other informations but applied as a sticker.

toobadorz, that INR26650-55A is nothing but a paper launch. Well, there's nowhere to get 'em, as far as I know.

I'd also prefer to buy non-rewrapped products, but that's a different story and, thus far, LiitoKala is doing nice. :THUMBS-UP:

Cheers ^:)

Hello Barkuti,

It’s difficult to get that INR26650-55A, but not impossible. Some Chinese sellers, like JAXMAN, do source some of this cell from PLB directly and sell them retail. I have some INR26650-55A and get satisfied with its performance. About 10% more runtime compared to INR26650-50A.

Regards.

Thank you HKJ for reviewing these cells as well and adding it to your impressive list of other great reviews!!! :+1:

The thoroughness & accuracy of your reviews never ceases to amaze me. :slight_smile:

Mitko, if your theory is correct (and it appears to me like it may very well be… :+1: .); have I labeled the pictures of the cells below correctly???

I had the impression that the manufacturer was the BAK from Korea.

Someone who has cells from the original batch and from the “probably fake” should test them in the same charger with the same parameters, its the only way to know for sure.

I thought/think this is correct also.

Just an fyi, The LK's are a little wider than most, maybe all 26650's and barely fit in the new Lumintop SD26. Some get a little stuck, some don't do too bad. I have the SD26 fully modded with a TA triple driver and the new NarsilTriple v1.3 running a XPL2 V6 3B, getting 8.6A (on an EFEST) out of it and 2,000 lumens.

I have 2 separate batch's of LK 50A's I bought, first original batch from 08/2016 GearBest and a 2nd batch from 12/2016 BangGood, slightly lower capacity, with the "F3" marker as shown above. What I think I'm seeing is variations between batch's, nothing more, but I don't have any missing the 3.6V label line though.

Ordered some from a new chinese shop , more on Tuesday that i will have them in my hands …

Ha nice
Got 6 of the old batch
2 unused for later.
Thanks for the review

Thanks for the review, HKJ. I’ve been waiting for this one.

Cheers!

Can someone confirm the cells with the missing 3.6V text line are ‘fake’ or under performing?

I cant say for sure that “the fake ones” are realy fakes, cause they work and they perform like…lets say Keepower 4200 with our fed dd drivers, yet there is a difference with the better liitokalas
Good ones are like 5200-5300ma and have lesser int resistance, “fake ones” are like 4800-4900ma and have higher int resistance

What about this pic that teacher posted ?

Shows high capacity for the batteries with the missing line . But i guess it is because it is in charge mode

To be clear, the picture I posted came from This Post by Mitko in another thread.

I was using it as an example of the “missing line”. :slight_smile:

Since that pic keeps coming up, I sure would appreciate it if somebody would give me a shout out on how to work and read that charger! I’ve had one for a long time, virtually never use it. Mine seems to stop the charge at some 4.17V, I NEED those extra 3 hundredths of a Volt! :slight_smile:

As far as reading internal resistance and checking capacity, I really don’t know how it works.

Got one last week .

When i mentioned the exact same line ( Mine seems to stop the charge at some 4.17V, I NEED those extra 3 hundredths of a Volt!
) to some people in another forum they thought i’m crazy :stuck_out_tongue: Mine stops too at 4.17V .

Here are some words from HKJ’s review , i hope they help a little :

When display is flashing it is possible to select mode and current.
Using the slot button it is possible to reselect a slot and change parameters for it, also when charger is working.
When putting multiple batteries in the charger at the same time, it is possible to select mode and current simultaneous for all of them (Very nice).

When charging or discharging it is possible to use the DISPLAY button to select between V, mA and mAh.
The display button can also be used when the charge/discharge is finished, but the charger will change back to “full” display rather quickly.

Are the “the fake ones” suitable for high drain flashlights?
Thanks

Honestly, I don't like much the way the Opus-C3100 works: PWM charge current, PWM over its load current beyond the power supply's rating, fan, etc.

At times, I've thought how “easy” would be to attach inexpensive CC/CV modules to slider trays, mounting them with volt and amp meters (DIY crowd, of course). With knob attached external potentiometers, that would really be a li-ion/LiFePO4 “dreamcharger”. These modules are easy to buy for less than $2 a pop. Examples:
