I thought we were trying to determine if those Liitokala 26650’s were any good. Not comparing them to 18650’s.

Maybe I missed something???


True, you have not seen the most important thing. And about this I have already said a little higher. However, if you do not understand, then I can repeat that you can’t fully check advertising promises for these blue Lii-5100 (or 5000), having a regular device with a discharge current of only 500mA, as advertising promises 20А. Who needs your 500mA, if people buy 26650 for large currents (not at all for 500mA) Question

Does anyone know if this is the same battery that Intl-Outdoor is selling as a package option with the Emisar D4S? Is it a good battery to power the XP-L Hi’s on the D4S?

Thanks!


They show to sell the Liitokala 5000mah, not 5100mah. I can’t find any pictures. I would guess they use the proven older cyan or black cells that so many of us use for high powered lights.

If anyone knows what battery they use for sure, please post it.

The blue 5100mAh cells are well under 5000mAh at 1500mA.

My real LiitoKala Black and Gold -50A cells test over 5000mAh on the same primative toy engineering chargers. On top of that, the AC impedance of the blue cells is higher than the black and gold.

I would be very surprised if using a high-precision constant current load, 4-terminal battery holder and $2000 bench DMM finds the Blue 5100mAH “LiitoKala” cells are 5100mAH as advertised or even as good as the 5000mAh black and golds.

Ok. I’m done.


And you “done” good!! Beer

Those cells are dogs compared to the Liitokala Black & the Original Liitokala’s we got a couple of years ago.

They don’t carry Liitokala brand, what cells were you asking about?

All of their 26650 KeepPowers are the old and outdated 5200mah which are not very good.

Yes, I agree that KeepPowers is rubbish. Just need to know more details about the elements of KeepPowers 26650 6000mAh (?)

Only the 5200 version KeepPower is the old and outdated one.

Check out HKJ and Moochs review for the Shockli 5500. 

We even have a thread on the Keeppower 6000mah here at BLF.

Understand, instead of specific and visual graphs, everything there is just words and assumptions, which may or may not be a fact.
The fact is that today there is no confidence in anything. For example, no one knows for sure if these are the current black and white 26650 banks from Shockli, what were the former red-black Shockli-5500, previously tested by the master HKJ and the results of which we all have long been familiar with? Then how can you confidently talk about something about the new models KeepPower-6000, which HKJ has not yet really tested under the same conditions as all the others?

I bought them from a very popular Chinese website. I gave $ 5 per piece. Now on 11.11 I ordered $ 4.35 piece Smile I already have enough. Innocent

Thanks for the link, here it is in international version and de-rubbished (all unnecessary url characters removed):

Lucky Electronics Store @ AliExpress

They look to be selling genuine first brand cells. There are also some strange affairs in the “26650 Battery - OTHER” section, namely what seems to be two chinese OEM cell types (cian blue and blue wraps) and non-genuine Panasonic 26650s

It’s hard to have confidence in anything. If You have confidence in the Keeppower 6000mah is what matters. Others have said they measure the same capacity and perform exactly the same as the Shockli 5500mah. If your confidence about them is low, buy the Shockli version.

volchyonok, those oversized images mess up with the forum layout, you can reduce their size and fit them to screen by adding a {width=100%} prefix after the first exclamation mark in the insert image simple post editor code. For example:

!{width:100%}https://ru.nkon.nl/magento17/media/catalog/product/cache/10/image/4741a7...!

A better solution is to always use the advanced post editor, beats the standard one in nearly every aspect.

Not to get even more off topic, lol, but where can I find legit shockli 5500mah?

I see a black shockli at Mtn Electronics: http://www.mtnelectronics.com/index.php?route=product/product&product_id...

I trust them. So if this is “the good one” I might check it out. But back on topic…

I have the black and gold lito that came with my D4S. It came from int-outdoor. It’s been killler! Charged and discharged it about 16 times already. No percieved loss of performance. I beat it down to just about 3v and charge it back to 4.2 — I think my SkyRC measured IR in the 30s.

Yes, this is a normal store, so a little earlier, I already showed this place.

Also here are the natural cells of the Shockli-5500

Barkuti, I just love people who quote a post with 10 or more 10Meg pictures. And only add the word: nice!

Nothing against these stores but I don’t buy batteries from gearbest, Ali, banggood. I would rather pay a few more bucks for peace of mind.

I don’t even make a lot of money. far far from it.

Gearbest and Banggood are big stores and get large shipments of batteries. They only want to sell genuine cells. On rare occasions they may get fakes, but once they find this out they will stop selling them and reimburse those who got the fakes.

Aliexpress is made up of many small independent stores just like eBay. As with eBay, you have to know if the particular store your buying from carries legit cells or fakes.

I buy cells from all 3 of the above places.

NKON is another reputable foreign seller.

Since your in the USA, you have many legit stores to choose from. Illumn, Liion Wholesale, IMR and MTN Electronics. If you don’t trust the foreign sellers, then you should buy from USA stores. I plan to buy a pair of the Shockli 5500 once MTN gets them back in stock.

I’ve seen a lot of comments about the lightblue LiitoKalas of 5100mAh with paper label.

They indeed can measure above 5100mAh, I found as up to 5400mAh but the measurement is not relevant at 1A discharge (like Opus measures).
The cell is officially rated at 15A discharge so that’s how we must test discharge to see how it holds out.
Note that at 10A discharge there’s overheat, but the cell holds well. I could not measure capacity at high current values, but the cells should be fine at up to 10A.

My tests were done on a set of 12 cells, all showed between 5200 and 5400mAh @1Ad.

I purchased an Lii-500 Engineer charger and a LiitoKala Lii-50A 26650 during the recent Anniversary Sale at AliExpress, 3/28 thru 4/1. I purchased from the “liitokala Official Store”, currently reachable through links here and here. The store claims an opening date of January, 2013 and has an AE store number of 217753.


I received these items packaged together only 18 days after purchase to the United States, which is, by far, the fastest delivery I’ve experienced from AliExpress. The items appear to be packaged in factory boxes and the charger included all accessories and documentation.

The 26650 cell has been cycled once at 700mA charge and 500mA discharge rates. This reported a capacity of 5436mAh. Though somewhat higher than HKJ’s “Black” test, it’s in line with other owners when using the Lii-500 charger for testing. I cannot perform any high-current tests, but the charger reports an internal resistance averaging 27mOhm, which is also similar to other measurements of these cells with this charger.

I tested recently the black model, like in the picture above, at 1A discharge. Out of 10 cells, the average was 5700mAh and the maximum nearly 6k (5957) and minimum 5400+. They are definitely better than the light blue ones since they are also rated at up to 50A discharge.

I agree Overmind, Liitokala 26650 batteries are very good; I have a bunch of them in fact.
But if you will check close you will find that 50A you mentioned is not a rated discharge number….. it is a model/part number of the battery.

In other words they are not rated at 50A discharge.

Sorry to be the bearer of bad news…. Wink

They have never been rated that high, usually it’s 20A. Maybe you are confusing the model name of 50A (meaning 5000mah) with the amperage ratings? Some people do.

Also, if it measures well above 5000mah, that is not necessarily a good thing. The higher the capacity, the higher the internal resistance and usually the lower the amps.

Yes, of course it’s unlikely to give 50A. Probably they refer to bursts / spikes, not continuous use.

Max current is easy to test if you have some high power resistors (which I unfortunately don’t at this moment).

The 50A label of these cells is derived from the manufacturer cell model they started rewrapping, PLB INR26650-50A.

True, but because of lack of consistency. I sometimes build battery packs and for this cells with poor consistency suck in one way or the other.

Excuse me but given two cells of the same model (which means same chemistry and internal construction) the one with higher capacity will also be more current delivery and power capable.
