Removable battery pack and latch mechanism for securing a removable battery pack
Apparatuses and systems are disclosed for improved reliability in securing a removable battery pack. An example latch mechanism may include a flexible latch disposed on an outer housing of a removable battery pack, the flexible latch defining an inner surface facing the outer housing and an opposing outer surface, wherein a portion of the opposing outer surface of the flexible latch defines one or more locking tabs that are engageable with one or more engaging slots operatively positioned within a receiving battery enclosure, and wherein the flexible latch is deformable from a first open configuration to a second compressed configuration upon insertion into the battery enclosure.
