Master Battery is a part in Scrap Mechanic.
A single Master Battery is always found in the vicinity of structures that require power. The Crashed Maintenance Ship's Master Battery is found halfway up the nearby Ruin, sitting in front of some flaming debris. A Mechanic Station's Master Battery is found in the sleeping capsule labeled with a '2' in the nearby bunkhouse.
- The Master Battery was known as the "Power Core" earlier in development. This is evidenced by its internal name (obj_survivalobject_powercore) and the name of the command to obtain it in Dev Mode (/powercore).
- Added Master Battery.
