I understand the Powercell is supposed to be a multiblock, however, with that said... I would like it to also be like a Energy Cell, from Mekanism, Ender IO and Thermal Expansion. By that, I mean; It should act as a power source if placed in the 'power slot' of a machine that can be powered by a type of battery.

Main example is the Mekanism Digital Miner. If I placed the Powercell into the energy slot, it would pull from the powercell network, with the card in it. Due to the nature of the multiblock, when placed in a battery slot, it would NOT add to the multiblock's power storage. If you have 14m RF in storage, and placed an Advanced Powercell into the battery slot, it would stay at 14m, not go up to 18m.

Just some quality of life update, if I would say so myself, so have a gander at it if you feel this would fit in with the flow of the mod :)
