Energy cell

Energy cell, small energy cell, or simply small energy is an item of ammunition in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout Tactics and Fallout: Brotherhood of Steel. It is a small, self-contained energy storage unit often associated with one-handed energy weapons and acts essentially as a very powerful battery or capacitor. The Highwayman in Fallout 2 runs on energy cells.
