Abstract
A launch vehicle having one or more rocket engines, an electric turbopump, and a plurality of batter units. Subsets of the battery units are jettisonable from the launch vehicle using battery jettison mechanisms. The launch vehicle may also include a controller that may determine that a remaining battery capacity of a first proper subset of the battery units is no longer needed for the remaining duration of a flight of the launch vehicle and may then, responsive to such a determination, cause the first proper subset of the battery units to be jettisoned.
