Aircraft battery pack and associated cooling system

An electric-powered aircraft, comprising

• a rotor assembly;
• and
• an air-cooled battery pack, comprising:
• a plurality of battery cells disposed along a first direction;
• and
• a plurality of cooling members alternatingly disposed along the first direction with the plurality of battery cells;
• wherein air that cools the air-cooled battery pack is at least one of air displaced by the rotor assembly and ambient air received from an outside of the aircraft.

An electric-powered aircraft, comprising:

• at least one rotor assembly;
• and
• a liquid-cooled battery pack configured to power the at least one rotor assembly, comprising:
