An integrated, unitary battery pack may be formed and used as part of the structural support for a vehicle frame. The unitary battery pack includes arrays cells having all positive and negative electrical terminals aligned in-plane on a common face of the product assembly. The unitary battery pack includes cooling components for passively or actively cooling the cell arrays. The unitary battery pack is encased in a potting material that allows that forms part of the structure support for the unitary battery pack. The unitary batter pack may be integrated into the vehicle with or without additional support structures.
