A fail safe battery pack is disclosed and claimed wherein first and second housings are affixed together. A plurality of battery cells reside within and fixedly engage the first and the second housings. First and second printed circuit boards (PCBs) reside within first and second lattice structures of the first and second housings. A variable bias device resides in the first and/or second lattice structure of the first and second housing and engages the first and/or second PCBs. When the bias of the variable bias device is sufficiently large it overcomes a plurality of fixed mechanically biased devices operating between the PCB and the plurality of battery cells and tending to separate same and causes the PCB to electrically communicate with the plurality of battery cells. When the bias of the variable bias device is sufficiently small, the plurality of fixed mechanically biased devices separates the PCB and the plurality of battery cells rendering the battery cells in an electrically safe condition.
