Abstract: An electric drive work machine may include a body frame, a first electric power storage device mounted on the body frame, a second electric power storage device mounted on the body frame, and a junction box mounted on the body frame. The junction box may be operatively connected to the first electric power storage device by a first electric connection having a first inductance, and operatively connected to the second electric power storage device by a second electric connection having a second inductance. The first inductance may be equal to the second inductance such that power source charging power from the junction box is distributed equally to the first electric power storage device and the second electric power storage device, and power source output power to the junction box is drawn equally from the first electric power storage device and the second electric power storage device.
