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

Probably not C8-12, but C4-12? If it is a 4-slot device, then it has the ability to change the charging currents in this way:

for nickel: 0.1А / 0.2А / 0.3А / 0.4А / 0.5А / 0.6А / 0.7А / 0.8А / 0.9А / 1.0А and AUTO
for lithium: 0.1А / 0.2А / 0.3А / 0.5А / 0.8А / 1.0А / 1.5А / 2.0А / 2.5А / 3.0А and AUTO

So, most likely, you simply use the “auto” mode or the device after each new connection to the outlet always does it on its own, but you do not switch to manual mode to independently select charging currents.

They are ahead, especially since you do not have a normal powerful discharge device with a high discharge current to assess the current state of health of the elements you specified https://ru.aliexpress.com/item/150-60-10A/32879958043.html?spm=a2g0s.13010208.99999999.666.777d3c00WIQAlB

Yes, C4-12.

I manually set each cell to 3A. Sometimes it may go to 2.1A or 2.4A, etc… so I confirm 3A or else set it manually. I have no idea why you would assume I dont.

Edit: Oh, I see. You thought I was saying that charger only had one charge rate. My point was it only goes up to 3A.

My normal powerful discharge device is my modded Convoy L6 which drives a pair of them to 17A on turbo. I use it nightly at work.

I don’t know what “They are ahead” means.

Still waiting on the new blue ones.

FWIW my Black and Gold Lii-50A have been fine. All of them check test slightly over 5000mAh.

I never charge at more than 2A. None of my 26650 lights are especially demanding. (Convoy L6, Convoy BD06, Emisar D4S with 219c) The Emisar firmware limits turbo to 80%. I’ve run the D4s to thermal step-down several times and haven’t noticed any problems with the battery. The L6 draws 5A on high. The BD06 (7135 * 8) is only 2.8A on high.

Recent check of my last unused Black and Gold. It was sitting for about 10 months before the capacity test.

Aaah, you know it! What makes you know something?

Since you know, why are you asking here?

Am I smelling adamantness? Look here for the Love of God: https://www.powerlongbattery.com/battery-cells/li-ion-battery-for-electric-vehicle/3-6v-3-7v-5500mah-nicomn-battery-cell-for-evs.html

That is the official Power Long Battery page for the cell Shockli is rewrapping, and it says the following:

Charge current. Standard 0.5C (≈2.75A for a 5500mAh cell), max 1C (≈5.5A for a 5500mAh cell)

These recommendations you hear of maybe are just recommendations for Joe/Jane Sixpack (uneducated people who know no better). Shockli and his advices can suck my… bird.

Cheers :-)

Are you talking about “Chinese amps” - 17A or about familiar amps for all other countries? (I wonder how many parallel drivers in your lantern is 7135?)
This is already in the past, but earlier it was possible to find a small Chinese hand-held radio tape recorder, which was written about the power of its 1000W-2500W speakers … (lol)

And it is very good that you do not know :innocent:

Actually, these are not recommendations of the manufacturer and, moreover, in no way a guide for careful use with a long resource. This is just a guarantee that with such operation its batteries will not explode. Understand, if you took the place of PLB or some other manufacturer who needs sales, then you yourself would have written on your batteries and not such a nonsense. Moreover, the higher currents you give to your batteries, the faster you will come to the store to buy again - the main thing is sales and the money received, which allow you to survive and feed your children.
By the way, Shockli told you that his “5500” is from PLB or is it all just someone guesses on the forum?

Before choosing elements for a future battery, I dreamed of taking the batteries from Shockli (black version 5500). When the scenario “14S-3P” is 42 pieces, that is, it could be decent money. However, something went wrong and, unfortunately, it was just before my order that Shockli removed the discounts on this black model and on the black 21700, and when I asked to make an exception, then the seller from his store (woman) sent me to the choice of green “5250”, which I consider a real failure, and not the progress of Shockli. Interestingly, after my choice of batteries from another seller, Shockli returned the previous discounts on the model “5500”, so, apparently, It was not my fate to buy batteries from Shockli “and get a higher capacity (approximately 16.5Ah instead of 12Ah or even 11Ah with Golisi) :frowning:

Chinese amps…

It is right there in my signature if you want to know the answer. :wink:

@volchyonok, he isn’t using 7135s to achieve a peak of 17A on the XHP70.2 build.

He is using a FET direct drive type of driver.

I think he is more interested in tearing people down than listening to anyones advice. I would not waste my time.

Nobody asked you about 18650 to listen to any advice on them. I do not need these 18650s, and I have already told you all this many times (I even showed a graphic picture), so it was your own decision to waste your time in vain.
Indeed, there are too many other things in life to spend on studying batteries. However, I asked where you got the information that the Shockli-5500 are items from PLB? Why, for example, is it not a PAC?

Did anyone ever figure out, or was it determined; why those 3 Liitokala Blacks allegedly went ’nuclear’ when being charged??

Any more ‘back story’ about the situation??

Not worried about the one’s I have, just curious about what might be going on with these 3 “exploders”.

I suspect that if it was possible to communicate to ali-express as on a forum (write more than 1-2 times reviews), the list of exploded elements continued to grow. In this case, most likely, this is due to its IMAX charger, whose form of charging currents is very wrong. These elements of LiitoKala-5000 turned out to be especially sensitive to this. I personally never liked IMAX, especially because it causes a significant increase in the temperature of the batteries during charging (their chemistry just boils inside). In addition, this customer chose a charging current of 0.5C (with such current forms as IMAX - 2.5A - this is very much). The shape of the IMAX current is more like a stabilized power supply, rather than a pulse current of a normal charger.

However, it is not only in this example. Look carefully at other reviews, where some people who understand this will soon write about the utter unreliability of these LiitoKala-5000 (and many other versions of it too). That is, for some time they work quite normally, and then suddenly quickly lose their characteristics.

There’s no way to “communicate” on aliexpress. They always call you to vote for an article you’ve bought or to write a “review”, but if you’re writing straightforward and something you’ve bought is a POS (I really mean the article, not shipping or something else), the article you’ve wrote never is published or the article-number is deleted, but the article from this seller is published under a new article-number so that no one’s able to read your review.
The whole aliexpress voting- and review-system is buyer-scam.

I understand your frustration, but let me point out some advices:

Oh. In this case it was a wall charger. I’ve bought two of them, on usage they went so hot just near to firing up. So yes I was able to give a feedback next day or so. The charger called “Xenain” is in fact a dangerous peace of shit.
After that I’ve sent one of them to HKJ for testing and tear down. Maybe he’s writing a test once in a time.

So see this as a warning from Xenain 4-port wall charger Ke-Ke-QC-04.

Test is done and review written, it is in my publishing queue, my conclusion say: “This is a rather bad and dangerous usb power supply, stay away.”

volchyonok…… Thanks for the info on the IMAX charging being the suspected problem in this case.

Thank you! Please notice me via mail when you are publishing it!

I have published it today.

Thx.

After nearly 2 months, four blue 5100mAh “LiitoKala” 26650s arrived today.

These are different then the blue 5000mAh cells HKJ tested and probably different than the Black and Gold cells HKJ reviewed in this thread. The Black and Golds are sold by a different LiitoKala. liitokala.com.cn and liitokalahongkong.aliexpress < shrug >

The label on the blue wrap includes a link to the liitokala.aliexpress 133859 store I bought them from. Are they fake? Looks likely. Are they junk? The wrap and labels are sloppy. (see photo)

I’m analysing one now in my ISDT C4. It will take a few days to cycle through all four.
