4sevens Qmini CR2, my third actually. It's greatest feature is also it's biggest curse, I always lose it.
4 Trustfire 18650 and a charger although I don't have a flashlight for these (ordered them before I started looking for one because of DX shipping times and finally couldn't find a decent 18650 flashlight. Waiting for the Armytek Predator with XM-L right now.)
