System and method for securing battery in aircraft

A system for securement and disengagement of a battery assembly power source element for an electric vertical take-off and landing eVTOL aircraft comprising:

• the battery assembly configured to mechanically couple to the eVTOL aircraft and comprising:
• a battery element having opposite, opposing surfaces and configured to provide power to at least a portion of the eVTOL aircraft;
• and a pin element disposed on a surface of the battery assembly;
• and a receiver assembly disposed on the eVTOL aircraft and configured to mechanically couple the battery assembly to the eVTOL aircraft, wherein the receiver assembly comprises:
• an insertion opening disposed a distance away from the battery assembly and having a size configured to receive the battery assembly;
• and a hook assembly comprising:
• a hook configured to mechanically couple to the pin element of the battery assembly;
• a cam mechanically coupled to the hook;
• and a shaft mechanically coupled to the cam, wherein the shaft is configured to drive the hook such that the distance between the insertion opening and the battery assembly is changed.
