32 . The unmanned aerial vehicle of claim 21 , wherein each of the first battery compartment and the second battery compartment is operable to interchangeably receive each of the first battery and the second battery.

33 . The unmanned aerial vehicle of claim 21 , wherein the control system is further configured to remain at least partially active under power supplied by the second battery when the first battery is removed from the first battery compartment.

34 . An unmanned aerial vehicle, comprising:

a control system;

at least one rotor operable to generate lift under control of the control system; and

a chassis comprising:

a first battery compartment configured to receive a first battery and to supply power from the first battery to the control system when the first battery is installed to the first battery compartment; and

a second battery compartment configured to receive a second battery and to supply power from the second battery to the control system when the second battery is installed to the second battery compartment;

wherein the control system is operable to power the at least one rotor to lift the unmanned aerial vehicle (a) when the first battery is installed to the first battery compartment and the second battery is installed to the second battery compartment, (b) when the first battery is installed to the first battery compartment and no battery is not installed to the second battery compartment, and (c) when no battery is installed to the first battery compartment and the second battery is installed to the second battery compartment.

35 . The unmanned aerial vehicle of claim 34 , wherein the control system is configured to remain at least partially active under power supplied by an installed one of the first battery or the second battery when the other of the first battery or the second battery is uninstalled.

36 . The unmanned aerial vehicle of claim 34 , wherein the control system is configured to remain at least partially active under power supplied by the first battery when the second battery is removed from the second battery compartment; and
