OMFG! LiitoKala 26650-50A 5000mAh li-ions?

1PCS LiitoKala 26650-50A 5000mah 26650 Li-ion 3.7v Rechargeable Battery for Flashlight 20A

If this is serious :)) , we need a review ASAP!

Cheers everyone :-)

I think there´s just a 0 too much. 5A could be true, with the real capacity around 4000 mAh for those.
K.

Size-for-size, there is plenty reason to believe a 26650 can be 5000mAh, if a 18650 can be 3500mAh! In fact, if total volume is the determining factor, it should be possible to reach 7000mAh with current technology! And 50A discharge would only be a measly 10C rate for a 5000mAH cell - also easy to do! I can’t think of any reason not to believe a 50A 5000mAh cell exists!

Wait-a-minute! LOL at this nugget in the description:

No, folks, this cell cannot be used as a direct replacement for AA in any device!

26650-50A seems to be a sort of Samsung style model number.

5A continuous would, in fact, be considered a poor rating. 20A, a decent one, for sort of a 18650 2500mAh 10A rated 26650 equivalent battery.

Cheers ^:)

Surely there is some mistake in this part of the description “Exact replacement for standard AA size battery in all the devices.
Can be used as a exact replacement for standard AA size batteries in most all equipments.”
A 26650 is a completely different size & voltage to an AA ?
Also it also says 20A in the description so it is being rated at 50A pulse & 20A continuous.
Plenty of 26650 clls are rated at this or even higher with some rated at 64A pulse & 30A continuous.
However when they have been tested by HKJ or mooch it is has been found that the claims are exaggerated.
The price though, which I guess is what Barkuti was OMFG”ing about is exceptionally low so just to see I have ordered 2 pieces & will test them to see how they compare to my KP, Basen & Thorfire 26650 cells :wink:
I think I will need to buy some more 26650 form lights :slight_smile:

Liitokala make good quality chargers, I have 5 of them, so based on that I am prepared to risk $12 :slight_smile:
I did the same with the Thorfire 26650”s which were about the same price as these Liitokala 26650”s.
I knew that Thorfire made good quality lights as I already had 3 of them so took a chance when I saw them advertising 5000 mah INR 26650 cells & bought 2 & have been very happy with them :slight_smile:

Any reason to believe this is actually made by liitokala? I only see claim by seller, but nothing else.

Did you checked the seller's store? Snow White's store Electronics.

I like what I see there, pricing & product range wise.

Those ICR18650-30B perfect laptop pack overhauling units are well priced, except for the fact that 100 units is the minimum order.

Cheers ^:)

P.S.: one of those 26650-50A LiitoKala packs is calling me too…

The description states:

“Akku für Taschenlampe 20A” which means “Battery for flashlight 20A”.
Could hold the same cell as the Evva 26650/5200……?
If that is the case, its certainly NOT a high drain cell.

No obviously not the same as with other 26650 cells there is no way of knowing.
Thorfire for example claim they have their own cell factory making their own cells but I know for a fact that their 3000 mah 18650 cell is in fact a re-wrapped Samsung 30B.
So by their own cell do they actually mean their own re-wrap ?
I am led to believe that there are only a few factories making 26650”s which are then wrapped as various brands.
This Liitokala 26650 dosen”t have the word “fire” in the name & the specs are more than believable at 5000 mah 50A pulse & 20A continuous so for the price I am willing to take a gamble.
I will use my analysing charger which will show me ma capacity & IR during charge & discharge so that will tell me if the cell is any good.
I already have 26650 Keeppowers which are regarded as a good quality cell but the much cheaper Basen & Thorfire 26650”s I have have also proved to be good & for half the price of the KP”s so hopefully these “Liitokala”s will prove the same.
If not I have only wasted $12 :wink:

Well, I opened this thread for the fact that the only trustworthy reference I could figure behind these cell(s) is their brand name. If the cells manage to deliver close to 5000mAh with good 15+A performance, I'm sold. :THUMBS-UP:

Cheers ^:)

Even if the Liitokala 26650 cell proves only to be 20A pulse & 10A continuous drain it will still be more than enough for most lights which will typically only draw around 5A or so unless it is a modded monster.
At about 5 euro”s a piece they are about a third of what I paid for the KP”s so worth a gamble IMO & I was lucky with the cheap Basen”s & Thorfires I have already bought as they have proved to be good cells so far.

Right on. The closest thing I've seen are these HETER 4500mAh 3.7V 26650 INR Rechargeable Li-ion Battery - 2PCS BLUE which have not been formally reviewed, to my knowledge.

Cheers ^:)

Once I get the cells that I just ordered I will post up my results in this thread.
As I have said in a previous post these are more than likely just wrapped in Liitokala wraps as I doubt they have suddenly opened up their own cell factory & will have come from the same factory as several other “brands” of 26650”s.
I would guess that these will prove to really be somewhere between 25-40A pulse & 10-20A continuous drain cells.
I cannot discharge above 5A myself but certainly will be able to post capacity, ir & how they perform against my other 26650 cells.
I do not have any lights at present that draw more than about 5.5A so I guess they will be fine for me.

You can make an estimation of discharge capacity current handling ability by determining the battery's internal resistance. One of the easiest methods I can figure out for that is to measure, with a precise multimeter, the voltage at the battery terminals when applying a given load resistance to it: a 1Ω resistor, for example. After measuring the no load voltage, the measured load voltage (for a 1Ω resistor) should be equal to the current flow in amps. Thus, the no load minus load voltage delta divided by the current flow should equal the given battery's internal resistance.

Sorry if that is difficult to understand, I feel a bit thick today.

Cheers ^:)

We all know these are rewrapped and probably one of the same cells as the fake Basens in the fake Basen group buy

What is the problem with the Basen”s & why do you think that they were fake ?
This is a 15A constant drain test performed on a number of different 26650 cells & the Basen”s performed as well as the competition

Discharge capacity is what I said (and I meant current/power handling). The power lost inside the battery's innards is a function of I²R, which should be kept minimized and determines, not only the amount of power at the load, but also how fast the power source (battery) will heat up.

Gold rule: use a power source whose impedance is sufficiently enough orders of magnitude below the load impedance.

Cheers ^:)

P.S.: take a nasty full loaded ICR li-ion and shortcircuit it with a nice copper/alu cable and… hurry up! Throw that burning wick firecracker away LOL!

P.S.2: quick semantic fix.

On the front page of their store they list 3000mAh BTY AA cells.
I don’t trust them
