Heavy energy cell
|The following is based on Fallout: Brotherhood of Steel and has not been confirmed by canon sources.|
Heavy energy cell or simply heavy energy is a type of ammunition in Fallout: Brotherhood of Steel.
For some energy weapons which use a lot of power, small energy cells are not sufficient. These weapons use heavy energy cells, a larger, more advanced version of small energy cells. Harder to produce than their smaller cousins, they are big self-contained energy storage units.
