A Battery Box is a block designed to store Blutricity, the electrical medium of RedPower 2. It can store energy acquired through Thermopiles, RedPower Solar Panels, or Kinetic Generators with a Wooden Windmill or Wooden Wind Turbine. It can power any machines that use Blutricity to operate, from any side. Each side also has a visual battery level indicator. In prerelease 6 Battery Boxes now retain their charge when broken.
Blue Alloy Wire and Jacketed Blue Alloy Wire are used to transmit power to and from the block. An active Redstone signal can be directed to the Battery Box to cease the power supply.
