LiitoKala 26650-50A 5000mah 26650 - great first impressions

Ahhh - I knew bout that deal before I forgot bout it (huh?), well, that's me. But thanks!!! They are not shown in stock, due Nov 16th, but still worth while getting an order in for another 4 @$19.62 shipped and don't have to use any points! Excellent deal for sure... Thanks Again!!

Whoa !!!

Could this be a picture of LiitoKala 26650 heaven???

:+1:

Where is that picture from and what is it of?

Looks like a battery test/charge bay at a factory! Wish I had that many batteries.

That is what I would say too ‘mattlwrd’. :+1:
I wish I did too, along with the rack they are in…… :money_mouth_face:

Texas_Ace, I did a search for BAK batteries and this was one of the LINKS that came up. Scroll down for the photo.

I am not sure that I should trust you, that link led to Bing, who actually uses bing??

Google means your normal, DuckDuckGo means you understand how the world works.

Bing means something, just not sure what.

LOL

:smiley: … :+1:
That is the exact reason I use ‘Bing’ Texas_Ace……. I’m not “normal”. :wink:

teacher, thanks for sharing that Bing link, just noticed it actually works pretty well in my unnormal computing device (rooted Android, custom desktop browser user agent, tweaked dpi setting, etc). Comparatively, using Google image search results in the freakin' thing relocating the shown images dynamically as the stuff loads and it does so in a pestering and nauseating way with image showing pop-ups re-adjusting my browser's zoom and page scroll level, ffs. Here, look at this photo of myself yesterday after using it:

Cheers ^:)

Sure thing Barkuti, glad it was useful. :+1:

Yeah, from the “selfie”, it looks like using Google was a frustrating experience for you…… :smiley:
At least you have a chocolate chip cookie to ease the pain……… :wink:

Hello!

Fellows, I have good reasons to believe this cell can do a really nice 20A discharge curve and that, with a 2.8V cut-off, nearly 4.9Ah of capacity should be attained (maybe slightly more if the heating up of its internals results in a somewhat decrease on its internal resistance? Oops! Power output is what such a thing would drive up).

I say it because I am going to gamble on 'em for high power delivery, long story short here: Battery discharge curve analysis @E-CigaretteForum

Anyone willing to make a godblessed test on them?

Cheers ^:)

Sorry, just saw your comment.

Porn, you use Bing for porn. Seriously, search adult videos on Google and Bing, much better results on Bing.

…so I’ve heard from a friend. :smiley:

The good thing about Li26650 is that it combines great capacity and one of the lowest resistance values( maybe the best?) - thats is quite important to us especialy since we are using mostly fed dd drivers, speaking of this capacity comes second :wink:

As a digital smoker( already a year) i cant see its implement-its quite heavy and devices that uses it are heavy and not pocketable , maybe for home vaping yes but its quite another story

Mitko, with (personally estimated and in concordance with the CPF test) maybe slightly above 22mΩ of internal resistance, the Liito isn't the best in this regard.

However, capacity matters also. A lower IR helps with power delivery, but if the available capacity is a lesser one, the steeper discharge curve slope means the lower IR and lower capacity cell will end up delivering lesser power at some point and beyond.

This means that, even if certain quality 18650s like the VTC5 have slightly lower IR than a LiitoKala 26650-50A(B), soon they're stomped by the massive capacity and cooling performance advantage of these bigger cells.

Cheers

P.D.: Glad to know that about bing. :-)

VTC5 have slightly higher IR that Li26650 actualy, at least this shows my DD drivers :slight_smile:
Li26650 performs as VTC5A

iJoy 40A 4200mAh - this one has to be tested

Can anyone find cycle life specs for these cells… I agree that these cells are cheap, but I am thinking about using them in e-bike (14s2p) and to do this I have to do a lot of soldering, which would be too much work if they only lasted like 150 cycles (to 80%). Most of the time I will charge them to 4,1V (with 1,4A per cell) and discharge to 3,2V… I now use lipo Multistar 10Ah cells, which have low IR - no voltage sag (at a little over 1C discharge ) and are light, but cycle life is not that great and I notice they dont like cold (below 0 celsius). Would these Liitokala 26650 be any better in cold weather? I would only drain max 7A per cell (on average below 5A). Or is it better to buy well known NCR18650B and use them in 14s3p config (so around 4A current per cell)?

UDO

Well we dont know how will they perform on a long temr base
My personal ones i charged like 10 times so far, they work great

Cold weather could be an issue, Liions dont like temps below 10deg c
Last winter i went hunting one morning, the temps here could be quite moderate cold ones, that partucular morning they were like - 20 and i lost 4 Samsung 25rs

lost 4 25r?
i have a versapak kit in my trunk that went to 0f and the packs did fine in the drill driving a ton of drywall screws after an overnight cold soak.
never seen low temps kill cells only cut their performance till they warmed up.
these are green 25r and lg he4.
both did equally well.
using them at a high rate warms them a bit.

Mine came today.after careful calibration of the dick smith esr and a test that gave 20 mohms this is the lowest yet.they are getting better.
edit.
after full charge i repeated.
now if i press very hard on the pointy probes i can get to .01 blinking to .02
so 19 or 18 mohms

Where did you order from?
