Summary:An improved battery pack for night vision goggles is employed in the cockpit of an aircraft, where RF fields of several hundred volts/meter are present. The improved battery pack includes a shunt circuit for shunting RF signals picked up by any external leads from the battery pack, and a resistor for dissipating electromagnetic energy from the RF signals shunted by the shunt circuit.
