Anybody use these cells?
Tempted to get a pair, just curious if there is some real world use of them. Can’t find much with the google machine
Not worth risking it until a comprehensive review is done. Spend a few extra dollars and get proven quality and performance.
I think our favorite reviewer might have them somewhere in his queue?
Simon ( convoy) sells them in his store iirc, so hopefully they’re ok at least
I gave them a try.
4x Heter 26650 4500mAh arrived yesterday.
Voltage of all four was around 3.67V.
After loading to 4,2V I did a discharge test with one of them.
Result:
At 1.00 A discharge current the output was 4616mAh. Cut off Voltage 2,9V.
Seems to be quite ok so far.
Are this these cells?

They are going to give me storecredit and I got some lights that accept 26650 cells.
If you are in the states, it is pretty hard to beat the KingKong cells at Richard’s place. I think I would wait for the review, if they are not good they contain lots of energy and could cause problems.
Yes.
thanks JPLight, I now know what a part of that store credt is going to look like, thick cilindrical blueish 
My new favorite are these Basen cells: liionwholesale.com - basen-4500mah-26650 They performed better than any of my KK's, got a ton, and seem to be on par with the new dark purple EFEST 4200's in performance in FET based lights I tested them in.
Man, you bought them all?!? you should have left some for us
Just to let you know:
I did another discharge test.
Result:
At 3.00 A constant discharge current the output was 4587 mAh. Cut off Voltage 2,9V.
These cells might be better than expected.
Just my 2cent …
Mine are not in, but first thing I do with cells is charge discharge write mAh and mR (think the liitokala means internal resistance with this) on a small piece of paper and tape that on the cell.
In other words will give the values of mine about 12 hours after they have arrived.
Just for comparison only (This is not supposed to be a real test !):
Got a couple of Basen 26650 4500mAh now and did a discharge-test under the same conditions and with exactly the same equipment as I did with the Heter 26650 4500mAh (see #4).
Result:
At 1.00A discharge current the output was 4196mAh. Cut off Voltage 2,9V.
Hmm … kind of surprising for me.
3A discharge-test is running.
I repeated my last test on the Basen 26650 as I wasn´t sure if everything went right.
So here is my final result:
4249 mAh at 1A discharge current. Cut off at 2,9V.
4171 mAh at 3A discharge current. Cut off at 2,9V.
I´m really curious on the test results by HKJ.
I have 7 Basen 4500’s now. At least 2 tested showed over 4500, about 4600 mAh.
Strange …
Discharge current ?
1A, or maybe 1.5A, using the Opus BT-3100 charger. I’ve tested lots of batteries the same way with good results. All the Basen cells I tested showed over 4500 mAh, but think I only tested 2 or 3 of the 7 or so I have. No telling though what the real cell is, and things happen between batch’s, etc. Recently I got 4 EFEST 4200’s that tested at 3500 mAh, later confirmed by the vendor. EFEST told him it was limited to one batch, but who really knows what’s goin on.
Could be fakes of course, or re-labels, or intentional or unintentional sourcing problems. Frustrating with so many unknowns and consistency issues. Had similar problems with KeepPower. Whenever they hide the true manufacturer, seems like anything can happen.
Hmm this can’t be right
They came today, charged and started discharge right after seeing full.
The liitokala and thus the cells got a bit warm, logical with those two 26650 cells on discharge heat is generated and the size blocks more air then a 18650, so I removed 1
The one still testing voltage just jumped down to 2,9 and it says 4991.
I noticed the new Panasonics were charged to 4,23V a bit high. So maybe the charger overcharges (will test that later because is important) but it is no explanation for this high man right? The Panasonics all measured very close or even a little bit higher then the 3400mAh specs.
This Heter is more then 10% higher ???
Yes it is finished,
92,4 grams
9hours, 52minutes
500mA discharge
10mR
5011mAh
(Got a Ultrafire 26650 I did not order, 88,9 grams, 53mR, 1740mAh,
I wonder what accounts for those grams.)
If this is correct this is a real good buy! Thanks OP!
Boy, lots of bad specs goin around. Sure it’s possible - basically equal to cells correctly labeled at 5000 mAh. The 13.5A max discharge rating is maybe roughly the same as the 5000 mAh cells around under various labels. Not sure bout the voltage jump though - might need re-testing to eliminate your doubts. Of course the capacity could vary quite a bit from cell to cell, or batch to batch.
I’m not really interested in cells like this though - they are lower in performance for max amps in FET based single cell drivers, but higher capacity.
The second is done
time 9 hours 52 minutes
500mA discharge
10mR
5001mAh
The cell was fully charged and when I had it off the charger for an hour it read 4.25V (too high :()
Will test the charger today with other cells, I usually take the cells of at 4.1V thinking it does stress them less to do so instead of fully charge them. I will measure, and see what the actual charging state is full and at 4.1 later today.
