What 'good' 26650's??

Batteries and Chargers Rechargeable Batteries

one of the best 26650 you can get

and good price as well

22

Jerommel, the volume of a 26650 is (theoretically) about 2.086419753086 times that of a 18650. So, your figures are “a bit” above what nowadays could be considered “state of the art” li-ion battery capacity volumetric index.

Not for US - Shipping doubles the price. GB went totally insane w/shipping batteries now. What's the shipping for you guys?

24

Shipping Cost:$18.49 to United States Via Registered Air Mail

Yeah it is pretty bad when the shipping is about equal to the price of the batteries…… :person_facepalming:
I am just thankful I got as many as I did before the ‘shipping insanity’ set in. :slight_smile:

27

Thanks for the tip Barkuti!!! :+1: … :beer:
Price ends up at $5.00 US per battery with free shipping. I “had to” order 6. :person_facepalming: … :smiley:

He tests 17 of them and lists the Top 5 and comments on the others as far as their performance.

+1 on the newer shorter Keeppower protected 5200mAh 26650 cells.

30

O, only twice the volume? I thought 3 times.
Then > 5000 mAh is not so bad afterall.
Thanks.

Orbtronic Protected 5200mAh
Over 5000mAh at 9Amp load
Dimensions: 26.4 mm x 69.1 mm

Thanks for reposting that graph resized, teacher.

Comments about that Orbtronic 26650 discharge curve:

  • Initial dV above 0.4V for a 9A load, which means about twice the internal resistance of a LiitoKala 26650-50A/B cell.

  • Discharge measured down to 2.5V, which is quite significant here because the battery was being discharged at what could be considered its maximum continuous rate (or nearly).

  • As I see it, ≈4130mAh for a 3V cut-off and ≈4840mAh for 2.8V cut-off.

Not in the same league as LiitoKala 26650-50A/Bs (or Soshine NCR26650s, which I presume to be rewraps of the PLB INR26650-50As too).

Cheers ^:)

My pleasure ‘Barkuti’, it was a bit large for me to follow as it was. :wink:
Thank you for the commentary you provided above on the Orbtronic 26650 discharge curve. What you said seems right on target to me. :+1:
The Orbtronic does not even come close to the Liitokala as I see it.
Truly, as you said; not even in the same league as the Liitokala’s……… :slight_smile:

35

LiitoKala 26650-50A/Bs
Post discharge test graph please. Cannot find any.
I am very interested to see LiitoKala at 50 Amp load, but 10 Amp is good enough. :slight_smile:

This is protected cell for flashlights, of course unprotected LiitoKala is not in the same range when we are using them in flashlights.
What is average current draw of flashlight?

36

I think 50 Amp is a ‘pulse’ load for the Liitokala’s, IIRC they are rated for 20Amp continious.

37

It is NOT worth much after 10A according to the guy[mooch] testing 17 x 26650’s. I guess for a simple flashlight that does not require high drains it would be ok.Other wise this battery finished at the bottom out of all that he tested!

Here is the link again.

The 26650 current champ (LoL :-) on the play on words) is the IJOY INR26650 4200mAh, available at FastTech for a reasonable price. Reviewed by Mooch here.

In flashlight use, these could serve to build some stupidly hot-rodded quad emitter setups. Is this nuts?

Cheers ^:)

39

Thanks,At First I wondered why he did not include the IJOY in the 17 X 26650 test! Then I looked at the dates. The 17 X 26650 thread was done in January 2016. This test for the IJOY was done in September 2016. I guess it is relatively new or he just did not have it for the January test?

Good luck in finding 2 cells that match in performance
Just saw the graph of Liitokala LoL

IJOY 26650 40A

Tester is tired and not paying attention or something else is wrong:
From his test:
“At 25A continuous the temperature rose to 69°C. This is still below the average temperature of a cell operating at its CDR and is an indication that we are operating below its true rating.”

From IJOY 26650 specs:
Temperature range: –20 to +60 Degree Celsius

It looks promising, but you have to buy 10 cells to pick 2 that match in performance.

My favorite 26650 cells are those 75Amp and 80Amp

Way to go.
