Orders from GB? I'd order more but shipping is killing the deal now. $18.49 for shipping of 4 cells for $20.39.

But here, from your OP: https://www.aliexpress.com/item/1PCS-LiitoKala-26650-50A-5000mah-26650-Li-ion-3-7v-Rechargeable-Battery-for-Flashlight-20A/32591381104.html

$6.53 each in 12 ours from now, plus $3.79 shipping. Might be best deal.

But actually still cheaper at here depending on qty. For 4, at $7.10 each, best deal.

Tom E. Regarding a post of yours I saw. How are you getting over 200kcd out of your Manker U21? If i may ask. :). I tried to read if you had modded, but couldn’t find it.

Ohh - yes, fully modded, dedomed XPL V6 0D, Narsil, FET+1 driver, springs bypassed, etc. Got ~1,700 lumens and 240 kcd. Also uses the RED LED under the switch for Narsil functionality.

Light Junkie sent me his non-working U21 (driver died) and modded it up same way but used a dedomed XPL W2 1A (AliExpress), and got 1,780 lumens and 253 kcd.

The LK is the reigning champ - best cell for this modded U21.

Wow! Yeah I figured it’d be something fancy and out of my league. :). Provide a service if i decide I get bored with my U21? Big Smile

Well its the best for all fed dd drivers, i got 6.7 amps reading w2 1a and this cell, first time to see 300k mcs from a L2 host

I order both from GB and Ali stores, late orders came same as the first ones, it seems they do supply from a same provider

Tom E, please check M4D M4X´s deals thread. There's a groovy discount code for the LiitoKalas at Banggood which, combined with the volume discounts, makes it the best deal nearly all of the times. Make it your mantra: 975e07, 975e07, 975e07…

Cheers Party

Old good kind is back , the last 2 orders that i got came to be from the good old ones

I`ve tested them agains the newest Efest purple model and Li 26650 performed better with our fet dd drivers

Yet, they dont perform great with buck drivers, for instance Efest 5200 or Soshine 5500 works better with them


Can you detail their behavior with buck drivers? That’s my primary use of my Liito’s.

unknown00101, nothing new with buck drivers. Understand, please, that a buck driver can have (and usually have) a long voltage differential between input and output, making the batteries' internal resistance much less meaningful versus overall capacity. For buck drivers fed by 2S li-ions driving 2S emitters, it should be noticeable.

 

Cheers Party

Oh I see. I thought you meant something specific to the Liito cell itself.

My main attraction to these cells is the price per mAh. The low resistance is a very large cherry on top. Smile

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!!

I wish I did too, along with the rack they are in….. Cash

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.

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:

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 Party

Sorry, just saw your comment.

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

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.

Source: iJoy 40A 4200mAh 26650 Bench Test Results...overrated but a great 30A battery! @E-CigaretteForum

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. Smile

VTC5 have slightly higher IR that Li26650 actualy, at least this shows my DD drivers 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)?

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
