An electrical system provides propulsive power to a rotor system of an eVTOL aircraft. The electrical system includes a power battery system having a plurality of power cells and a power battery management system. An energy battery system includes a plurality of energy cells and an energy battery management system in communication with the power battery management system. A distribution system electrically couples the power battery system and the energy battery system to at least one electric motor that drives the rotor system. In a takeoff and landing power mode of the eVTOL aircraft, both the power battery system and the energy battery system provide electrical power to the at least one electric motor. In a cruise power mode of the eVTOL aircraft, the energy battery system provides electrical power to the at least one electric motor and to the power battery system to recharge the power cells.
