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

Perhaps the arrival voltage could show if a cell is old and in rested condition has lost some voltage? Or just as a reference point? Or truth in disclosure, stating everything the charge cycle showed them?

Sometimes I notice that when charging em up the first time, usually I don’t pay it a lot of mind. As long as all 4 are very similar that’s all I care to see. So maybe in this way you know the 4 cells are matched, not one old one from 2 years ago and 3 new ones. So yeah, it could be pretty relevant if you’re using all 4 cells in one light (which I am, these)

I don’t know. I always do it too. Just SOP as far as I am concerned. I like to know what they are when I get them & always just share it.

I honestly had no idea there was some kind of regulation that mandated 3.8V. :smiley:

I might be wrong on that. It was either 3.8v for air travel so it’s mostly discharged or 3.8v might be the best voltage to store a cell at long term. Either way the battery companies always seem to send them out at that voltage.

I pick up way too much random info at BLF. Lol

Me too. I received the 4 black 26650… took 24 days… i am happy with it… now I am waiting for the series connector… I am planning to use it on

Liitokala in convoy l6 mod.
Shockli 5500 mAh in trustfire tr j20 mod…

Mentioning the arrive voltage is some sort of a tradition, it has always been this way. I think they do a couple cycles to the cell and set the end voltage to 3.7 or 3.8V, and if some cell arrives differently it means a bad cell or inconsistency in the QC process. I do like to see perfectly matched cells on arrival and after discharge cycles, probably that information can help others too.

BTW it is extremely easy to add a solder blob top to the cells, just sightly sand the top, use your iron on the highest setting and use a low melt solder. It is way more reliable than using the spacer and reduces resistance.

Barkuti .
I just asked for losses.
Nothing else.

I do not know the way you propose and I asked to have a better picture.

I got my black ones a few days ago
Lii500 measured:
5238
5323
5307
5235

Only downside is that they don’t fit in those holders: https://www.aliexpress.com/item/10-Pcs-26650-Lithium-Ion-Cell-Battery-Holder-Bracket-For-Diy-Battery-Pack/32768155893.html because they are bigger in diameter - there might be flashlights where those cells don’t fit.

Aaah, you mean metal spillings, shadockan? None. :-)

I have a couple of LiitoKalas from a dismantled, work in progress powerbank, but it doesn't looks very fine on these as they only have a “dismantled” wire solder. ;-)

I have to solderblob a TrustFire IMR14500 (red-gold) for a friend soon, and he already has one of those done plus an NCR18650B. I'll recall for a nice picture of this to be shot.

Just tested between my blue and black LiitoKala 26650’s in a modified Convoy L6 (FET driver, XHP-70.2)….

Blue showed me 16.48A and did 9,108 in the light box
Black showed me 18.16A and did 9,280.5 in the light box.

192 lumens more at the sacrifice of 1.68A more draw, seems odd, but I’ve seen it where it flips, the one that has highest current doesn’t necessarily produce the most lumens.

I guess that proves the new black one are just as good as the older blue.

Now we need names. We can’t just say liitokala any more. I guess it’s liitokala blue and liitokala black?

Resistor modded L6:

Old: 6.85A
New: 7.28A

Not bad!

The Hengi Battery cell maybe (26650-50B)?

I mentioned it in some message up there.

Thank you Barkuti.

thanks i was about to ask this exact question. Will order a couple Liitokala 26650 soon for my L6

Amateur, I build with my friend some bike packs.
Welds should be in such a way that there is as little loss as possible.

Nothing special of course, but now I have seen a problem with the BMS and the Volts cut off.

I’m generally looking for the problem ……….

Thank you .

Hi Newlumen

Good weekend .Now shockli 26650 5500mah have button top.it

is good contact for series .

I will keep in mind… I bought 26650 series connector already… in the future, I will purchase that button top.

shadockan, I never said I was into assembling packs profesionally. Doing it with this solder and technique can be relatively fast, yet I believe this is more adequate for custom builds and high current, as I can use and solder very big wires with ease.

I don’t have a solder machine…

How much do the Shockli’s cost?
