1. A battery pack comprising:
a first cell block including first and second battery cells, wherein the first cell block is characterized by a first side surface, a second side surface, a third side surface opposite the first side surface, and a fourth side surface opposite the second side surface;
a second cell block adjacent the first cell block along the third side surface of the first cell block, wherein the second cell block includes third and fourth battery cells, and wherein the second cell block is characterized by a first side surface, a second side surface, a third side surface opposite the first side surface, and a fourth side surface opposite the second side surface;
a third cell block adjacent the second cell block along the third side surface of the second cell block, wherein the third cell block includes fifth and sixth battery cells, and wherein the third cell block is characterized by a first side surface, a second side surface, a third side surface opposite the first side surface, and a fourth side surface opposite the second side surface;
a bypass busbar extending from the first cell block to the third cell block, wherein the bypass busbar electrically couples the first battery cell with the fifth battery cell, and wherein the bypass busbar extends across the second cell block and is electrically isolated from the third and fourth battery cells;
a first internal busbar entirely disposed within the first cell block and electrically connecting the first battery cell to the second battery cell;
a second internal busbar entirely disposed within the second cell block and electrically connecting the third battery cell to the fourth battery cell; and
a third internal busbar entirely disposed within the third cell block and electrically connecting the fifth battery cell to the sixth battery cell.
