A reversibly connected battery pack is provided. The reversibly connected battery pack includes a pair of end frames, at least one frame, a plurality of battery cells, and at least one power connector. One end frame has a positive terminal, and the other has a negative terminal. The frame(s) is positioned between the pair of end frames. Each of the plurality of battery cells has a positive tab and a negative tab. The positive tab of one of the plurality of battery cells is electrically connected to the positive terminal in the end frame, and the negative tab of another one of the plurality of battery cells is electrically connected to the negative terminal in the end frame. The plurality of battery cells are positioned in the frame(s) and the end frames. The plurality of battery cells and the positive and negative tabs are supported by the frame and the pair of end frames. There is at least one power connector electrically connecting the negative tab of one battery cell with the positive tab of an adjacent battery cell.

A method, system, and computer program product for automated root cause identification of a failure of a logic controller have been provided. The method includes receiving logic controller failure information, receiving a logic model of logic code for the logic controller, and mapping the logic controller failure information to the logic model to identify a logic failure model state. The method further includes determining a potential trigger of the failure of the logic controller as a root cause via tracing through at least one path in the logic model to reach the logic failure model state. The method also includes identifying the root cause in the logic code via mapping the root cause from the logic model to the logic code, and outputting the logic code with the identified root cause of the failure of the logic controller.
