The Mountain Prophet from Germany issued his list of Favorit 26650 on his blog.
Unfortunately I can not relink his results, I will just Name them.

He devides between high capacity batteries and High-Current.

High-Capacity:
  • Keeppower IMR 26650 (10 A / 5200 mAh)
  • Enercig / Tensai 26650 (15 A / 4700 mAh)

High-Power:
  • Enercig / Tensai 3200mAh (32A/3200mAh)
  • MNKE 26650 (mit 15-20A/3500mAh)
  • Keeppower 26650 (20A/3500mAh)

I'd go with Mooch's recommendations:

Regarding the recommanded 26650 from Mooch, I don´t know them, if to be honest. Basen, Efest and AWT have a bad Image in Germany, while Keepower and Enercig are more popular...AW has a good Reputation, but too expensive (to my opinion).
18650 - I like the 25R and the Sanyo UR18650NSX. I use my eVic Mini on daily use and didn´t replace my batteries so far (I guess each of them has around 120 cycles so far). However I have to admit, that I don´t go above 15W

Mooch has done actual testing, and has released the results here, so his recommendations are spot on.

    For 18650's, I would agree wih you. But there are only a few different cells used for all of the 26650's and none of them are Samsung/Sony/LG. The Basen, Brillipower, and Efest all use the same cell under the wrap and can be considered to be the same battery.

    Mooch - I agree with you completly. 26650 Li-Ion you can find some really old versions from Panasonic and Sony, that are not really relevant for eCigarette users. All other manufacturer are Chinese. 2 or 3 of them are good and the others...waste of time. I know one manufacturer of 26650 (High-Capacity) that use the cells for own products (batteries for electric busses in China). The cell has UL and IEC...but still it is chinese made.

    I guess Mooch can confirm that (or not), but there is no battery 26650 with more than 4000 mAh, that is a high-discharge-current (Power-Tool) battery Li-Ion. Most of 26650 above this capacity are 3C batteries.

    High-Discharge-Current batteries in this size have according to my experience not more than 3500 mAh.

    In my testing, all of the 5200mAh batteries were rated at about 10A.
    The 3500-4500mAh 26650's went up to about 23A-25A.

    Just found your list of recommanded 26650 and saw that your test went up to 15A.
    Is there a list of batteries with more than 4000 mAh that reach continously the 20A?
    Would like to test them for a RC-Project (just balacing cable and no protection). Up to now found only 2 manufacturer with UL that could make the 20A...however with 3200 mAh and 3300 mAh ;-(

    Several 4200-4500mAh 26650's have actual or estimated CDR's of 25A. Check the 26650 performance and ratings table in my blog.
