Results are in from my second pair of Liitokala 26650”s
Cell 1, IR during charge 20, IR during discharge 21, capacity 5104 ma
Cell 2, IR during charge 17, IR during discharge 19, capacity 5211 ma
Good figures all round again & well matched, very very close to my first pair
First pair were from Aliexpress & second pair were from GearBest.
Do these “sag” under 5a load?
Vsag = I × Rbatt
Since people is reporting low IR values (20 - 30ish mΩ), sag complaints are unlikely to arise.
Seem to be awesome cells, yet I'll refrain from ringing the bells too early, at least until I can see some properly obtained IR figures, HKJ or other reputable techie test them, and or I can make some tests on them (not soon).
Cheers ^:)
Received the first two batteries and Lii-500 charger today and have them on the charger running a nor test at 1A.
IR for cell 1 is 23 and cell 2 is 21 during the charge and discharge phases. Cell 1 5011mAh and cell 2 5098mAh. Since the Lii-500 terminates discharge at 2.8v but typically cell specs state 2.5v the actual capacity is well above the listed 5000mAh.
I decided to order two more yesterday and using my points again the total for all four cells I’ve ordered from gearbest was $20.50 including tracking.
I suspect it’s an abbreviation for ‘normal’ since there’s also a fast test.
Whatever “nor test” is meant to be, the charger does a normal test when set to “nor”.
My second order was “scanned by X ray and returned”….well… i do hope at least GB one to arrive, it seems that declaring those as kitchen goods dont work always .
X ray FTW
I also received a pair from gearbest. For 10$ it is a steal!
Both cells measure 5600mAh in my charger and power a FET driven XHP70 light with 8A at start!
Better then my keeppower 5200 cells!
My first 4 is in from Aliexpress, and the result on Opus 2.2 is around 5200mAh on each. So very good. Do see that others gets even higher numbers, but I did only do one test @1A
My second pair should be here in a few days since the package was processed through isc chicago three days ago. The first pair is working fine in my Convoy L5 (LD-29 driver) after swapping in a xm-l2 u3 2c, bypassing springs, foil wrapping the pill, and fabricating a copper insert to deal with tailcap contact and switch centering. Time to order some resistors to boost output current. The batteries are making + to - contact just fine in a 2s without a magnet. Fit is a bit snug but they slide in with no effort.
Got mine in today… Charged in the Liitokala Lii-100, rested 30 minutes and wow! I pulled 6.45A in my favorite pocket rocket. It is an Uniquefire UF-2200 with all springs bypassed, XM-L2 4C and a very strong driver! I am liking these batteries, my KK 26650’s could not sustain that much.
Yes m8, i allready got 8 of those and i can cleary call those the best all arround 26650 batteries in existance so far- lets hope they dont ” nuke” them as it usualy happenes
Received second pair and they’re currently in the charger under test. Ir 18 and 21 milliohms. I consider the $5/5000+mAh a real bargain. @Mitko - thanks for pointing them out. They were a nice addition to my LiIon supply.
5$?
It shows 9.20$ for me!
Gearbest still selling it @ $5.36/pc.
I got mine from them 2 weeks ago. Good deal
$9.xx will get you a Keeppower Black
That’s $5 each. I got 4 cells total for a bit over $20 including 2x mandatory $1.99 tracking (two separate purchases) after discounts for gearbest points.
Thanks for the info, I was looking on aliexpress
I see they have discount: 4 pcs = $19.99, I am tempted!
You can get a pair of these at gearbest for around $10 http://www.gearbest.com/batteries/pp_360841.html
$9.xx will get you a Keeppower Black Big Smile
That battery is inferiour vs Li26650, both 4200 and 5200
LiitoKala 26650-50A is the best overall 26650 battery atm and prolly the best high amp battery for our BLF fet dd drivers
