Redstone Energy Cell (Thermal Expansion 3)

The Redstone Energy Cell is a stationary and portable battery for MJ. It can be charged by supplying it with BuildCraft power, and discharged like an Engine (i. e. with Wooden Conductive Pipes or Redstone Energy Conduits). The maximum input and output rates can be configured in its GUI.

It will retain its charge even when mined or picked up with a compatible wrench, making it an easy-to-use portable battery. Just like an Engine it can power machines directly without the need for a Wooden Conductive Pipe in between.

Recipe
The first step in making a Redstone Energy Cell is the Energy Storage Frame, which can be crafted with four Electrum Ingots, four Hardened Glass, and one Diamond.

Next is the Energy Storage (Empty), which can be crafted with one Electrum Ingots, two Lead Ingots, one Energy Storage Frame, and one Redstone Conductance Coil.

The Energy Storage (Empty) must then be filled with Destabilized Redstone in a Liquid Transposer to finish making the Redstone Energy Cell. This requires 4 buckets of Destabilized Redstone, equivalent to 40 Redstone Dust.
