Given the space of a tube (a laser pointer) for 2xAAA batteries, what are the best batteries to power a Cree XR-E or Luxeon Rebel or SSC P4 LED, wanting the maximum brightness for 10 minutes?
Energizer lithium L92.
And what's up with starting so many threads practically talking about the same thing.....
There are only so many batteries available commercially.... and if you decide to go with li-on 10440, be careful that the capacity is only 300mah... its probably safer to stick within 1.5C.
