Abstract: This disclosure relates generally to high voltage power supply (HVPS) systems and battery assemblies for aircraft that use electrical propulsion systems. In one embodiment, an apparatus for safely venting battery cells in thermal runaway is provided. The apparatus includes: a mechanical support layer, the mechanical support layer configured to be attached to a battery assembly; and a vent flap layer attached to the mechanical support layer, the vent flap layer including vent flaps corresponding to battery cells in the battery assembly. Each vent flap includes one or more portions configured to deform to permit flow of gas from the battery cell corresponding to the vent flap.
