## Abstract

A swappable battery pack system includes a casing and a battery pack. A first pair of rail elements, a first pair of guide elements and a first connector are positioned on an inner surface of at least one of a side plane of the casing. A battery pack adapted to be slidably disposed within the casing includes a second pair of guide elements, rail elements and a second connector coupled to the outer surface of the battery pack. In the event of sliding the battery pack within the casing, the first pair of rail elements engage with the second pair of guide elements, the first pair of guide elements engage with the second pair of rail elements and the first connector is received within the second connector to form a complete connection, thereby providing power to an entity affixed to the casing.
