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

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.

The originally rewrapped cells are known to be a little bit wider (≈∅26.7mm) than other 26650s. Measure them, carefully remove those stickers to see what's going on underside and take a shoot at the wrap markings. If willing to, unwrap them. Make a nice close up shot of their positive poles. If you are able measure their DC internal resistance, should be no higher than 28mΩ.

Cheers :-)

I don’t think “fake” is the correct word. How can a new, original product be fake? It can’t be.

I think you mean you suspect the capacity to be incorrect or the cells to not be very good. Do you suspect they are not actually Liitokala brand?

I’m very curious about your tests. I wish you had a light with a FET driver, xhp70.2 that used 2 of these cells to see how many amps it’s pulls. Do you already have an idea of its internal resistance?

The cell that is undergoing analysis read out 85mΩ at the start of the discharge cycle. It is currently at –1.5A, 3.42V, –4116mAh and 107mΩ.

I measured the three that aren’t in the C4.

∅26.65 - 26.67mm
≈L 52.30 - 52.58mm

Here is a look at the top
