Quick update.

I recharged all my 18650's to 4.2/4.21 V and tested the current at the tail cap. Here are the results:

1) Ultrafire 3600 mAh (fake I know)__2.35 A
2) Ultrafire 3600 mAh (fake I know)__2.8 A
3) NCR18650A 3100 Panasonic______3.8 A - Not too impressed with this one, internal resistance is 76 mOhm and its less than 1 year old...
4) NCR18650B 3400 Panasonic______4.2 A
5) NCR18650B 3400 Panasonic______4.25 A
and the winner!!

6) AW IMR 18650 2000 mAh________4.6 A!

Panasonic has a low IR, high current 2900mah cell:

Of course, I would not torture the Cree XML any more. :evil:
