A connector assembly for voltage monitoring battery cells of a battery module includes a connector having a plurality of terminals and a wire assembly extending from the connector along a wire axis. The wire assembly has a plurality of wires extending between a terminal end and a buss bar end. The terminal end is terminated to a corresponding terminal. The buss bar end is configured to be terminated to a voltage sensor associated with a corresponding buss bar of the battery module. The buss bar end is folded over such that the buss bar end extends at a transverse angle relative to the wire axis. The buss bar ends are staggered along the wire axis at different depths from the connector.
