A battery pack assembly includes a plurality of battery cells and a pair of elongated connector terminal plates. Each battery cell has a terminal side and an opposite floor side. A pair of terminals extend from each of the plurality of battery cells on the terminal side. Each of the pair of elongated connector terminal plates includes an upper and a lower elongated terminal connector. The upper and lower elongated terminal connector plates of each of the pair of elongated connector terminal plates are configured to independently move between an aligned position and an engaged position such that in the engaged position the pair of elongated connector terminal plates retain the plurality of battery cells and in the aligned position the pair of elongated connector terminal plates are removed from the battery pack releasing the plurality of battery cells.
