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

No idea what if any difference there is teacher but they definitely all work in both my S70 & Z1 XHP 50 (the only 2 x 26650 lights I have).
To look at the cells you wouldn”t think that they would work in series without a magnet or such like as the tops are very flat & I am surprised myself that they do.

I have had good results too with Soshine 5500 batteries; they will especially work well in a two battery in series set up.

BTW I have the batteries of this thread on order. :slight_smile:

That is certainly interesting. I look forward to seeing if my next 4, that are in transit now; will work in series.
Thanks for the info & ‘consumer report’ bella-headlight………… :+1: … :wink:

On the +ve side or -ve? Tradition would say on the +ve to make them feels like “button top” but I see advantages of placing them on the -ve to protect the bottom plate from sharp tail springs of certain flashlights.

So, wait a minute… Are there two versions of this battery? On Ali they are listed as 50A batteries and gearbest states they are 20A. Has this been discussed already? Sorry if so…

I am waiting on these batteries, but from the photographs they look like these would not be a good candidate for using in series. I plan on using mine in my single cell lights.

I am waiting too on the Convoy L6 but plan on using Shockli 4200mAh batteries; they are flat-top batteries with the positive terminal high enough for good contact. Not all flat top batteries can be used in series because of a shallow positive terminal.

Hmmmmm, good eye on spotting that. :+1: I have no idea what the answer is though.

I received 4 from GearBest about a month ago. They are marked like this. ( the black hand writing is mine of course. )

None of my first 4 work in series. I think bella-headlight said all his did. No idea what the difference is besides the obvious.

I have 4 more on the way from GearBest that should be here in a week or so…… maybe. :wink:

I’ll see if I can find any difference when they arrive.

PPDB22, the below is what I was told by a reliable source concerning your question.

With regard to the Liitokala 26650“s the 50A rating is pulse discharge & the 20A rating continuous discharge.

Ah. Ok, thanks. That makes sense.

Sure thing, glad to know myself. :+1: … :slight_smile:

Oh man! I totally forgot about ordering two from AliExpress and they arrived today.
Since I was no longer aware they were coming I thought Gearbest f#*ked up LOL

They are on the charger now but when done I will compare them to yours Teacher (seems like I’m the only having them from AliExpress)

Hmm 2 heters 6 littokalas 1 On The Road 1 OrcaTorch = 10 (and a poor Ultrafire only used in testing)
Permanent in use 4 (L6/S70)
Nice to have loaded OrcaTorch and On The Road X5, Convoy BD01 and BD06.
I got two too much. Well one for the Z1 instead of high drain Keep power.
OK 1 for another MTG2 or Luminus SST 90 modded Z1. OK I am good, thought a sec I needed a new light :smiley:

Just got my pair today from GB, first discharge test with my MC3000:

Discharge rate 1A, down to 2.75V with termination current 0.2A:
Batt #1 5,128mAh
Batt #2 5,210mAh

Great capacity and consistent IR. They DON’T work in series no matter how much pressure I put on them. This is the shortest 26650 cell I have, about 3mm shorter than a button top KK.

For the current price this is the highest capacity/dollar cell in any format!

Hmm
First mAh test done
5428 mAh 11mR

the other is still testing

Teacher posted

Mine are the same except for the last 5 digitsof the lower row
08344 for the 5428mAh one
and
20776 for the one still testing

I saw it stop the discharge test at 2.8V.
An overshoot of almost 10%, I only hope the other ene gets close or this first one is a Convoy filler. (And still no decent cells to fill both L6 and S70 with now.)

But IDK, the one tested came at 3.8V and the other 3.4V, and well it had to charge 0.4V more is now on 3.4V going down,

Was the test done in a Opus? I think the it throws a higher than actual reading when doing discharge tests, when I had my C3100 v2.2 a samsung 30Q yielded almost 3,100mAh which is unrealistic, the same cell in my SkyRC tested less at 2,890mAh even when a lower cutoff voltage and termination current was used.

I could test again down to 2.5V and at 500mA rate, probably about 50-100mA additional can be extracted but I’m not sure about how far can this cell be safely discharged.

No Liitokala engineer 300

I have one of those 1 bay Opus chargers that got good reviews, don’t like it, with this warm weather it gets too warm

Just love my Liitokala :slight_smile:
(Though even when that is not as warm as the Opus it still is warm with 27°C where I use it so I hook up two small PC fans (1/underneath and 1 blowing over the cells with a piece of 10*10*0,8cm copper resting on that tiny fan and the cells))

Internal Resistance

HKJ wrote in his review the IR is not good.
I push cells up to disconnect and see it a couple of times
then go with the lowest and some cells are gradually getting higher (the ones I use for testing now that it is all lights with build in chargers)

Second done
5401

5428 11mR
5401 12mR
Ah nice, these seem close enough to put in the L6 then.

I use my chargers that give internal resistance and other parameters as mere guide lines; I would not expect a plus $30 charger to give accurate results.

I do use the results found by chargers like Opus as a way to match batteries that are used in series. :slight_smile:

Yeah same here
I kind of think that using the same device means about the same faults so still nice comparison

And the four Gearbest Liitokala cells just came in
Time for more charging tests.

OK the first two coming frm Gearbest are done:

5355mAh 10mR
5450mAh 10mR

(Ali Express ones)
5428mAh 11mR
5401mAh 12mR

The last two ar now on the charger for testing.
