I bought from 10× 26650 “old ones” from here (https://www.aliexpress.com/item/10PCS-LiitoKala-26650-50A-5000mah-26650-...) 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?

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. Thumbs Up

That helps a lot actually. It shows they are all pretty close to & over advertised capacity. Smile

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.

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).

I found two Hengji Battery, it appears anyway. Any idea which is the “real one” as far as what we are discussing?

CuriousOne @CPF - Test/Review of LiitoKala INR 26650 5000mAh cells. wrote:

For testing purposes, I will call 2 pack cells "A" and "B", and will 
call single pack cell as "C" cell.
As online shops love to show inflated specs for the batteries, I 
decided to do a search, and find real manufacturer of these cells, so 
I can have more precise information about cells available. By using 
help from a skilled Chinese friend, I was able to determine (with 
high probability, around 99%) makers of these cells. In case of "C" 
cell, this is Chinese company, called "PLB": 
http://www.plb.com.cn/Products/rlx5000mas.html In case of "A" and 
"B" cells, maker is "Hengji Battery", website and battery specs were 
not found. Assuming that cells should be mostly similar, I will use 
specs for battery "C", as a reference for others too. So, specs are 
as follows:

Capacity: 5000mAh
Charge current: 2.5A
Charge cut-off current: 100mA
Nominal discharge: 5A, with 2.75V cutoff
Max. discharge current: 5C (25A)
So I will be using above data for testing (except cut-off voltage, as 
practice showed, belov 3V, discharge to 2.75V delivered maybe 30-
40mAh, so I decided not to force cells to that extent). 
The results are as follows:
Capacity, mAh:
Cell A: 4922
Cell B: 4900
Cell C: 5002
Energy, Wh
Cell A: 16.88
Cell B: 16.81
Cell C: 17.06
Internal resistance
Cell A: 22 milliohms
Cell B: 22 milliohms
Cell C: 23 milliohms
Weight
Cell A: 91.5 grams
Cell B: 91.2 grams
Cell C: 93.2 grams
Dimensions:
Cell A & B: 65.15mm length, 26.52mm diameter, Positive pin is about 
0.5mm below shrink wrap.
Cell C: 64.82mm length, 26.62mm diameter, Positive pin is at level of shrink wrap.

It’s funny that the 50A and 50B have similar markings and use a similar shade of blue. But they are different enough to think they are made by different companies. I agree the 50B also seems like a great cell. I have one of each and use them in series. From that CPF test their capacities are very close so I have no worries about using them in series.

Yeah, I hear you. But it does make perfect sense & matches up with what we found here too concerning the ‘A’ vs. ‘B’.

That being (in a nutshell), the ‘A’ cells have more capacity than the ‘B’ cells when “tested” the same way on the same chargers. They were Lii 500’s located in the USA & Wales UK. Best I remember I had/have 10 A’s & 8 B’s…. I think Ian had 8 A’s & 4 B’s.

Other people who reported also had similiar results. ‘A’ has more capacity than ‘B’… though it be slight (around 150 mAh IIRC) and most every cell was above the rated capacity of 5000 mAh.

Personally, I hope these “new” ones are made by PLB & spec in real life as the original ‘A’ cell did/do.

Time will tell I guess….. Smile

Those are the “new” ones. Hopefully they will be… They should be.
If you have a charger that will check discharge capacity, check them when you get them. That will tell the story… most of it anyway. Smile

Thanks.. hopefully they works great in two 26650 series. Else I may have to buy connector or solder blop..

They sell battery series connector for 26650 or 18650.. about $1.07 each..

Your welcome. Maybe they will, on all the others I have some will & some won’t. No rhyme or reason to it either… just luck of the draw. Smile

That connector is what I use on the one’s that need it. Only bad thing about buying those 1 or 2 at a time is shipping kills you …… Facepalm

So I bought a handful of them last time I bought and the shipping was not much more than buying one. Wink

If you want one PM me your address and I’ll send you one. Thumbs Up

Your welcome… my pleasure.
Wait till you need it if you wish, or go ahead & let me get it in the mail for you to have when you need it. Wink

Really looking forward to the info on the “new” LiitoKala batteries when you get them too. Thumbs Up

In case any of you still wanna bet on the blue winning horse, take a look here: C-26650 @ Colaier Direct Sales Store

Received a couple 30Qs from them two days ago, tad slow shipping yet all good in every other respect.

Some 5500mAh 26650 did come up a few month ago (can’t remember when or where, but same baby blue wrapping) and i would have expected LiitoKala to follow up…

Testing now a pair of blues from GB i received a couple month ago. No “F1” on the first line of label.

PS: Both cells came out over 5150mAh on my Opus BT C3100 at 1A – which is known to be a tad optimistic. Those are from the last batch GB was selling a couple month ago – they are out of stock now. On their pictures the cells had only one line of text above the bar code whereas the ones i received and tested have two.

+ 3.6V 18.0Wh F1 -
INR26650-50A VB15I19D 03327

I haven’t tried them in serie.

So far they look like the real thing – whatever it is.

Just ordered a pair of these Lii-50A 26650

Got the code here: Gearbest Official Deal thread (July 8th part 2 – code still works today)
When they arrive I’ll test capacity on my Lii-500 charger/analyzer and post the results here.

Yep, appreciate the tip beam0… Thumbs Up

I got four on the way. I’ll be interested to compare them with my originals also.

It probably won’t be anytime soon though… I chose Free Shipping. Big Smile

No problem, yeah great price, hope they’re good. I finally went to order those blue ones and found out about the change over to these.
I did the standard shipping but I added the shipping insurance ($1.20) …probably should have got the 4-pack.

Just receive mine new ones, I can tell you that they can’t be connected in series and that they came with 3.8V in them. Put one of them for NOR test and I will post result here after finish.

Well… not quiet as good as the light blue ones it seems. But, still right at the rated capacity. Thumbs Up

I don’t see any problem since capacity is as it says on the battery.
The only complaint for now is that they can’t been connected in series.
