1. An unmanned aerial vehicle (UAV), comprising:
a direct current (DC)/DC converter configured to receive high voltage DC over a tether connected to the UAV and provide converted high voltage DC to a high power bus on the UAV, wherein the high power bus is configured to provide the converted high voltage DC to one or more motors on the UAV, and wherein the one or more motors are configured to drive a plurality of rotors to control flight of the UAV;
a radio configured to provide cellular communications;
a battery configured to provide a lower voltage DC to a low power bus, the lower voltage DC having a voltage lower than the converted high voltage DC; and
a power management circuit configured to:
monitor power available from the DC/DC converter and the battery; and
selectively draw power from the battery based on the monitoring,
wherein the UAV is configured to initialize UAV operation using only power drawn from the battery prior to a receipt of the high voltage DC over the tether.
