Abstract: Battery packs for aircraft are provided, as are aircraft comprising such battery packs. One such battery pack comprises: a housing enclosing a plurality of battery cells; and an air channel. The air channel is connectable to an aircraft air inlet and an aircraft air outlet whereby, during flight of the aircraft, air enters the aircraft through the air inlet, passes through the battery pack air channel and exits the aircraft through the air outlet. At least a portion of a surface of the air channel is in thermal contact with the battery cells, whereby air flowing through the air channel exchanges heat with the battery cells through the surface of the air channel without entering the housing and contacting the battery cells.
