Battery pack for failure safety

An electric aircraft with a battery pack for failure safety, the electric aircraft comprising:

• a fuselage having a longitudinal axis;
• and
• a battery pack disposed within the fuselage, wherein the battery pack comprises:
• a pack casing mounted to the fuselage, wherein the pack casing comprises an inner lining;
• a crush zone positioned parallel to the longitudinal axis beneath a battery module, wherein the crush zone comprises an energy absorbing material configured to compress as a function of a crash force;
• a battery module connection that attaches the battery module to the pack casing, and wherein the battery module connection is configured to disconnect in response to the crash force;
• and
• a secondary crush zone that is located between a top of the battery module and an upper wall, wherein the secondary crush zone increases in thickness as the battery module is guided downward towards the crush zone;
• wherein the inner lining is configured to guide the battery module towards the crush zone when the battery module connection is disconnected.
