1. A reversibly connected battery pack comprising:

  • a pair of end frames, one end frame having a positive terminal and the other end frame having a negative terminal;

    at least one frame positioned between the pair of end frames such that a stackable relationship between the pair of end frames and the frame is formed thereby;

    a plurality of battery cells, each of the plurality of battery cells having a positive tab and a negative tab disposed on opposite sides of the battery cell such that the positive tab of one of the plurality of battery cells is electrically connected to the positive terminal, and the negative tab of another one of the plurality of battery cells is electrically connected to the negative terminal, the plurality of battery cells positioned in the frame and the pair of end frames such that the plurality of battery cells and the positive and negative tabs are supported by the frame and the pair of end frames such that each of the plurality of battery cells are independently removable from the battery pack; and

    a plurality of external power connectors providing electrical connection between the cells through an external buss line, each external power connector comprising a spring-loaded conductive clip removeably inserted substantially within said at least one frame such that a contact surface is formed on opposite stackable sides of said at least one frame and each external power connector contacts and electrically connects the negative tab of one of the plurality of battery cells and the positive tab of an adjacent one of the plurality of battery cells, without reliance on stacking pressure.
