Rotatable terminal plate housing assemblies and methods thereof

A battery pack assembly comprising:

• a plurality of housing segments, each one of the plurality of housing segments comprising:
• a terminal receiving portion;
• and
• a tube portion, the tube portion having a first half and a second half hingedly attached to the first half such that the second half moves between a closed position and an open position, the first half is coupled to the terminal receiving portion, the first and second halves each include a tube attachment portion that is received a tube retainer portion of an adjacent housing segment,
• wherein the housing segment is coupled to the adjacent housing segment of the plurality of housing segments when the tube attachment portion of the housing segment is received in the tube retainer portion of the adjacent housing segment and the second half of the tube portion is in the closed position.

A method of removing a battery cell from a battery pack assembly, the method comprising:

• identifying the battery cell of a plurality of battery cells to be removed from the battery pack assembly;
• removing at least one fastener from each corresponding pair of terminals of the identified battery cell and an adjacent battery cell of the plurality of battery cells;
• moving an individual housing segment of a plurality of housing segments corresponding to the identified battery cell from a use position to a maintenance position;
• and
