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

Yesterday i received my 2 pcs. I put them to the test with my Opus.
1 cell at 1A - 5434mAh
2 cell at 1A - 5534mAh

I will test them these days on my L6 and will see how they perform.

Received one from Banggood. Did discharge test in Opus BT-C100: 4898mAh. A bit disappointing. Impedance test afterwards showed 76mR.

Just noticed that the product listing has disappeared from Banggood…

Interesting, I picked up some of these because of good reports earlier, but I have not tested them, waiting for some nice new light. Maybe I will test them when my test charges arrives and then put them back at storage voltage until I have a need for them. They sure seem like a pretty good bargain.

Well HKJ has now reviewed these cells & says about them “The cell live up to its rating and is one of the top performers for 26650 at the current time.”

Thanks for that link! As far as I am concerned this pretty well verifies what we thought all along. :+1:

Which brings me to another realization.
If HKJ’s “Discharge Capacity numbers” are accurate, and I feel sure they are; my LiitoKala Lii-500 is much more accurate than my Opus BT C-3100 v2.2 when measuring “Discharge Capacity”. Interesting……… :wink:

Edit: Forgot to say…… :person_facepalming:
My Opus reads consistently high, and from some of the Opus numbers some others have posted in the past, mine appears not to be the only one. :wink:

Yes I think that it is generally accepted that the OPUS is a little “optimistic” in terms of cell capacity.
My OPUS certainly is.

“Optimistic” that is a very scholarly way to say that!! I “b” impresseded. :+1:
Do you happen to be a “scholar” ??? :wink:
:innocent:
Edit: I was doing some looking back on things I had written down, and best I remember Ian; you and I compared numbers from LiitoKala 26650’s done on both chargers. Our numbers were very comparable for both chargers as each of us has a Lii-500 & a BT C-3100. Pretty interesting results for two different continents. :wink:

Yes our numbers were almost identical.
These cells have proved to be pretty uniform in capacity tests done by many different members :+1:
It is nice also to now have HKJ”s review to confirm what many members have experienced with these cells.
Also the Lii-500 chargers seem to be pretty consistent as well :slight_smile:

Well said, I agree completely. :+1:

Anyone ordered recently and got the good batch? from where?

Thanks

GB flash sale tdy for 1pc. Ordered 2pcs…

Is there anywhere to get these with free shipping any more?

Just ordered qty 4 of the singles - shipping to us is only $3.73 now for qty 4, much less than previous. I was able to use some pts so got it down to $21.95 shipped for 4.

haha, I did the exact same!

GB ones are exellent though! The last 5-6 shimpents came kinda slow yet they are from the good ones

After 40-50 cycles mine still test at 5200 mah on my opus. I do tend to baby them. No more then 1 amp charging usually very rarely 2 amps. And if no other cells need charging I’ll let them charge at 500mah overnight

Edit wanted to add my opus slightly undercharges. So capacity may have been slightly higher if it was charged to 4.20 or higher. I regret not getting another 4 of these cells last summer. I regret not stocking up on old xpg2 as well. But I digress.

My vc2 goes to the high end of 4.23-4.24 which is fine with me its within spec. My liito 100 overcharges. Just saw the other day 4.27 and was on the right setting. Wonder how long its been cooking my cells.

Did these work in your L6 without modification? I was wondering if they will need a solder blob to work in series?

It depends sometimes two work with no modification. And sometimes they don’t. The jaxman connecters work great. And cheap. I ended up taking a small knife and bending each of the openings on the top just barely up so they make contact. Works flawlessly now. Its luck of the draw some peoples work in series without a blob or connector and some don’t.

These are flat tops and will not work in the L6 without modification. I just bought a Jaxman battery adapter instead of trying to solder on the batteries.

I have a dozen of these cells bought in 3 separate purchases from 2 different suppliers.
Yes they are flat tops but over half mine, 8 out of 12 I think, work in series as they are.
Impossible to see if they will work in series unless you try (I initially assumed none of mine would).
If they don”t then solder blob, Jaxman cell connector or a slight bend of the button top will sort them out.
The ones that work in series with no mods I use in series in a Thorfire S70 & a Z1 XHP50 with no problems :+1:
