A battery cell interconnect and voltage sensing assembly and a method for coupling a battery cell assembly thereto are provided. The battery cell interconnect and voltage sensing assembly includes a frame member holding a plurality of electrical interconnect members and a circuit board with an electrical connector. The assembly routes an electrical current from battery cell assemblies through the electrical interconnect members and can allow a voltage at each of the electrical interconnect members to be sensed at the electrical connector.
