Stackable battery apparatuses and methods of use

An apparatus, comprising:

• a base member comprising a first protruding adapter and a charging adapter;
• and
• a first battery assembly, comprising:
• a housing having a first surface, and a second surface, wherein the second surface of the housing comprises a receiving interface that mates with a first protruding adapter of the base member, further wherein the first surface of the housing comprises a second protruding adapter that mates with the receiving interface of a second battery assembly;
• an energy storage unit disposed within the housing;
• a locking mechanism disposed within the housing;
• and
• a controller having a processor and memory for storing instructions, the processor being configured to execute the instructions to cause the locking mechanism to:
• engage with the first protruding adapter of the base member so as to lock the first battery assembly to the base member;
• and
• disengage from the first protruding adapter of the base member so as to unlock the first battery assembly such that it can be removed from the base member.

A system, comprising:

• an unmanned aerial vehicle comprising a primary battery and receiver that receives a first battery assembly;
• and
• a base member comprising a first protruding adapter and a charging adapter;
• the first battery assembly, comprising:
• a housing having a first surface and a second surface, wherein the second surface of the housing comprises a receiving interface that mates with either a base member or a second battery assembly, further wherein the first surface of the housing comprises a second protruding adapter that mates with the receiver of the unmanned aerial vehicle;
• an energy storage unit disposed within the housing;
• a locking mechanism disposed within the housing;
• and
• a controller having a processor and memory for storing instructions, the processor being configured to execute the instructions to cause the locking mechanism to:
• engage with the first protruding adapter of the base member so as to lock the first battery assembly to the base member;
• and
• disengage from the first protruding adapter of the base member so as to unlock the first battery assembly such that it can be removed from the base member.
