The Multi-Functional Electric storage unit, MFE Unit or MFE is the Tier 2 energy storage machine, after the BatBox and before the MFSU. One MFE is the equivalent of 15 BatBoxes. It is able to store up to 600,000 EU and can accept a maximum power of 128 EU from any of its 5 input faces. Just like the BatBox and the MFSU, it cannot accept any packets with a higher power, but can accept unlimited number of packets (so unlimited EU/t). It can also emit a current of 128 EU/t from its output face, meaning all first tier machines will explode if the output power is not converted through a LV Transformer. Note that the MFE unit will not explode if it reaches its storage capacity. The same applies to the MFSU Unit and the BatBox.
Like all storage units, its output face is marked by a special texture (a circle form), which usually faces the player when the block is placed. The direction of the output face can be changed by pressing "Right Click" with a Wrench onto any of the input faces of the block; normally, this will point the output face towards the player, but holding while clicking will point the output face in the opposite direction.
ATTENTION : Be aware that right-clicking the MFE Unit while pointing at its output face will dismantle it and you will loose all the EU within.
When a MFE is right clicked with an Energy Sensor Kit, it will give you an Energy Sensor Location Card, which can be used in the Industrial Information Panel to get constant info about that specific MFE.
NOTE : Applying a Redstone signal to the MFE Unit will make it stop emitting power from the output face.
ATTENTION : Copper Cables and Low Voltage Machines cannot handle Medium Voltage current. Do not try to hook them up directly to the MFE Unit. Use an LV Transformer (and make sure it's facing the right way) or else the machines will explode (luckily the explosion is not as powerful as a creeper explosion, and most likely won't destroy the machines around it, but will still destroy wires and other blocks)
