The Ultimate Energy Cube is the largest energy storage block available.
Ultimate Energy Cubes have the largest internal storage and discharge at a voltage of 480v.
Energy produced by generators can be stored in energy cubes for later use, they accept Universal Electricity, BuildCraft or Industrial Craft energy by connecting other generators and machines to them with Universal Cable. Cubes can accept power through the seven green faces, and release energy through the grey face. Energy cubes can also draw power from items placed within them or be used to recharge electric items.
Accessing the energy cube's GUI will display the total amount of power stored. The energy cube has two slots, + and -. Items placed in the + slot will be recharged by the cube, while items placed in the - slot will be drained of their power.
