An unmanned aerial vehicle (UAV) is described. The UAV includes a first battery to power multiple first and multiple second electronic components of UAV. A power consumption of each first electronic component is greater than a power threshold. A power consumption of each second electronic component is less than or equal to the power threshold. The UAV includes a generator and a battery management system (BMS). The generator generates an electrical power through rotation of a shaft of a motor of UAV. The BMS charges the first battery using the electrical power generated by the generator when the UAV is during operation and a stored charge of the first battery drops to a first predefined level, and charges a second battery using the stored charge of the first battery when a stored charge of the second battery drops to a second predefined level.
