Energy Cell (Thermal Expansion 4)/en

Energy Cells are tile entities added by. They store (RF) and can be picked up with a  or a pickaxe keeping the stored RF intact.

Usage
When the Energy Cell is placed all sides are set to input (blue) except the bottom which is set to output (orange). The Energy's GUI is able to configure redstone response, input and output rate, and face interaction. Redstone configuration will change whether or not the cell will output RF based on if it is receiving a redstone signal. The input and output rates can also be configured this will change how much RF per tick will be transferred. Finally the configuration tab will set sides to input (blue), output (orange), and closed (yellow).
