Yeah, but the GA’s are made that way by design.
With the LiitoKala’s is is just hit or miss… certainly not designed to work in series. Let us know how the “new” ones perform.
Ok from that point I can assume that there are many liito kala 26650 versions, some genuine some not.
Look at this, according to website http://www.liito-kala.com/ ( I don’t know is this theirs official website ), official Ali store is :
https://liitokala.aliexpress.com/store/133859
But when you look at 26650 offer you can find only one type of a battery :
And it is completely different from other LK batteries that you can find on Ali, GB, BG etc.
They have also Lii-500 with adapter for only $17.76 and free shipping.
Hmm all of this is very very strange I will contact them and ask for other betteries and link to tell me are they genuine or not.
/\\\
Possibly I guess. I just know that all of mine are very uniform & test above rated capacity.
Add this link to your three & it gets even more confusing… :person_facepalming: … 
Hahaha, this is unseen mess :person_facepalming:
This your link http://www.liitokala.com.cn are this store :
https://liitokalahongkong.aliexpress.com/store/217753?spm=2114.12010108.100004.2.nk2WIT
Since their email contact is the same liitokala@126.com, and they have same things on the web and Ali store.
Hmm, this store is old 4 years, and other two are 3 and 2 years, so I guess that first come genuine then other fake or whatever stores.
Or maybe one is worldwide other china. I contact them so I waiting for answer…
Good grief……. :person_facepalming: … 
“Official Stores” are everywhere…… 
Good find…… :+1:
OK, I contact them on :
emily@liito-kala.com
and
liitokala@126.com
First mail and website / store : http://www.liito-kala.com/ / https://liitokala.aliexpress.com/store/133859
No response at all.
Second liitokala@126.com I get very unprofessional answer which you can look here :
And I accidentally find this :
So GB are saying that there is a new version of liito kala 26650 cells that this stores confirms it :
And since they are 4 years old ( most of all others ), there is confirmation of new version of cells from GB, I get answer from them, I suppose that they are genuine store.
Thanks for the investigation, vidramon.
Definitively the LiitoKala brand is doing their stuff right. For whatever reason they've changed their 5000mAh cell provider, and this results in a completely new wrap with a clear “this is a different cell” insight.
Now, let's wait for HKJ to review 'em LoL. If any of you gives him notice say so please. ;)
Cheers 
I order this new version and when it arrive I can test a capacity of cells, for much more complex test we must wait and ask HKJ.
Also there is some chargers that I see on the store and can’t find on HKJ tests, so it will be good if HKJ can provide a test for it.
Great investigative work vidramon…… :+1:
Thanks for sharing the info.
Looking forward to hearing your results when you get the new cells.
I bought from 10x 26650 “old ones” from here (https://www.aliexpress.com/item/10PCS-LiitoKala-26650-50A-5000mah-26650-Li-ion-3-7v-Rechargeable-Battery-for-Flashlight-20A/32791838898.html?spm=2114.13010608.0.0.0sigkl) and tested them with lii-500, they seem to be legit.
Oh and the price was quite reasonable 34.88usd for the whole lot with free shipping.
Sounds good. What kind of capacities did you find if you don’t mind sharing?
It is available now.
Sorry but the notes are not now with me but if I recall correctly, I think that they were all around ~4950-5100. I know that this won’t help but I get my hands on my other laptop next weekend…I’ll post the exact numbers then.
Hey, no problem; thank you for the reply. :+1:
That helps a lot actually. It shows they are all pretty close to & over advertised capacity.
Well, hope this is just a proper rewrap of the cell from their provider. I am not a fan of downgrades, and the blue cell has certainly been a top reference by providing capacity above the wrap figures (how many cells from the big ones do that, eh?) and great discharge performance combined.
Exactly…… :+1:
Let’s hope the new version consistently makes series connection.
Yes, hopefully it is still the same cell manufactured by PowerLong Battery (PLB). Otherwise it will almost certainly be a downgrade.
Test/Review of LiitoKala INR26650-50A (26650-50B) @ CandlePowerForums
Even if they've decided to switch manufacturer to Hengji Battery, I see it good (a very bit less capacity, a bit better discharge performance, or thereabouts).
Are you saying that the 50B was made by hengji?
