Ender Chest Discharger

-- Ghetto tesseract part 2: Discharging.
-- Needs to be run in parallel with another turtle running part 1.
-- Use with thermal expansion energy cells.
-- Place Ender Chest above the turtle and the energy cell below. Make sure the cell plugs into something that will charge it.
-- Configure all sides of the energy cell to be output, bottom to be input.

-- Sleep to avoid overlapping grabs.

 battery = peripheral.wrap("bottom")
 -- This charges the energy cell
 while battery.getEnergyStored() > 0 do
  print("Energy at "..battery.getEnergyStored()..". Picking up.")
  os.sleep(2)
 end
 -- Now pick up the cell and put it into the ender chest.
