Zusammenfassung:	A first power source includes a high discharge rate battery and a second power source includes a high energy battery. An electronically activated switch switches between the first power source and the second power source in response to a control signal from a power controller. If the electronically activated switch fails, it fails with one of the first power source and the second power source in an open circuit position and with the other one of the first power source and the second power source in a closed circuit position. The power controller generates the control signal, including by: during a vertical landing associated with a vertical takeoff and landing (VTOL) vehicle, generating the control signal to switch from the high energy battery to the high discharge rate battery independent of a measured current.
