Are you at all interested in modding my Utorch UT02 (Manker U21)? I would certainly pay for materials. Maybe work a trade of some kind? Maybe a new in package Lumintop TD16? Or something else.
update.
i discovered high resistance in my test rig.banana plugs to my holder were losing their tension.
charged the cells again and started another discharge.holding 4.13v @ 1a at start.
was 3.96v.
so these are likely better than we thought.
stay tuned…
What do you want done with it? I like a dedomed XPL in it, but some might prefer it domed.
I received four from GearBest yesterday, first charge>discharge cycle @ 1A down to 2,8V :
I started the cycle this morning before I went to work so the cell voltage recovered a bit.
I am recharging them now :
What is the max current draw you get these from these in a direct drive set up? I just bought 6 shipping was 11 USD so i hope they do well.
well i found a bug.
kingkong 26.21mm
liitokala 26.63mm
too fat for one mod.
will post brand/model when i get it.
they fit all my lights though.
These are a bit wider and a bit shorter then most other 26650’s, it fits like a glove in the L6, it doesn’t fall when inserted it just slowly lowers itself to the bottom.
Gonna get some serious amps mangled from them pretty soon… 
The BMS low voltage/under discharge protection works well. I accidentally hard-shorted the BP+/B- terminals while assembling the stuff, a lil smoke crept away… 
Had to hook the thing up to the charger board to relive it. Quite interesting to notice my multimeter could actually measure some volts at the output terminals after the “accident”, a below 1Hz voltage signal oscillating between very high 6s and low 7s.
Cheers 
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……… 
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.
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” ???
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.
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 
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?
