Battery unit

A battery unit is a technology observed only on SkyTown, Elysia in Metroid Prime 3: Corruption. It is located in the Arrival Station, and connected to the holographic projector discs throughout SkyTown, with two of them found on either side of the unit. The battery unit, when scanned, is said to be in need of repairs. Despite this, the projectors display images of Ghor and later Aurora Unit 217 fine, if with a lot of static. The battery unit is located in the Arrival Station's small indoor room leading to Hub Access. It appears to be mounted to the ceiling and wall, with several thin cables running along the floor into a corridor from the outer station. Two glowing plates are attached to the unit as well; similar plates can be seen lined along the mentioned corridor next to the cable ends.
