Battery pack

A battery pack comprising:

• a housing;
• a set of battery cells disposed in the housing;
• and
• a latch assembly mechanism, the latch assembly mechanism comprising:
• a user activation button that pivots about a first axis, and an engaging portion that pivots about a second axis, wherein the first axis is parallel to the second axis and the user activation button actuates the engaging portion, and a spring disposed between a spring support and a bottom surface of a flat portion of the engaging portion.

A battery pack comprising:

• a housing;
• a set of battery cells disposed in the housing;
• and
• a multi-part latch assembly mechanism operable to mate and unmate the housing from a piece of equipment, wherein the multi-part latch assembly mechanism comprises:
• a first part of the multi-part latch assembly mechanism that pivots on a first shoulder about a first axis;
• and
• a second part of the multi-part latch assembly that pivots on a second shoulder about a second axis, wherein the first axis is parallel to the second axis,
• the first part of the multi-part latch assembly mechanism including a user activation button, a button extension, and a button extension arm;
• and
• the second part of the multi-part latch assembly mechanism including an engaging portion, a latch extension, and a latch extension arm,
• the button extension arm interfacing with the latch extension arm and the user activation button actuating the engaging portion through the button extension arm interfacing with the latch extension arm, and
• a spring disposed between the engaging portion and an inside surface of a top of the housing.
