Fairly high capacity, good current and not that expensive, is this cell as good as it looks?

Discharge curve looks good, the tracks fairly well and capacity is nearly constant up to 15A.

At 30A the cell get hot enough that I terminates the test a bit early.

Was about time, again perfect from HKJ

I could say only not “one of” but the best, especialy considering its low int resistance, price , capacity and perormance

P.S

Something else,

HKJ reviewed the better part of those batteries, there are others( prolly fakes?, or made by another manifacturer, or God knows who) that aint that good, they look like this:

They have higher int resistance abd lower capacity

I have one matching cell in the comparator.
The protected Soshine may also be the same cell.

I think it’s baby blue, not cyan.

Mitko can you show “real” VS “fake” ?

Edit : I guess the difference is on the words over the barcode.

@ HKJ,

Many Thanks.

Confirms what those of us who have these already know, they are really good batteries.

Interesting what Mitko said re. look-alike batteries.

He had already informed us that the 2nd batch seemed inferior, so, good to be able to tell them apart from the photo’s.

Cheers,

Finally, I got my priorities straight.

@ Mitko,

Thanks for helping us with the pictures of the Non-Original batteries.

Very Useful.

Nice I got some of these from Banggood back in early November for <5$ each, but now they don’t seem to carry them anymore. I wonder if Banggood may be getting out of batteries due to the shipping restrictions.

Did any of those underperforming “26650-50A” cells came from GearBest? Banggood? Aliexpress maybe?

This 5000mAh cell is actually manufactured by PLB (INR26650-50A, link). They also have a 5500mAh 26650 available (INR26650-55A, link), which is indeed the best 26650 known in the market (almost 6000mAh with 0.2C discharge!):

Shockli IMR26650 5000mAh is also the INR26650-50A cell from PLB, but some of them are of lower grade, i.e., smaller capacity. HKJ’s Shockli 5000mAh samples are also the ones of smaller capacity. 1 out of my 9 Shockli samples shows less capacity than the usual INR26650-50A (as HKJ’s test), while all the others are identical to the common INR26650-50A.

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

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!!! Thumbs Up

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

Mitko, if your theory is correct (and it appears to me like it may very well beThumbs Up .); 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.

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.

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
