While a 10mm Infantry Laser Cannon could be powered by the Jäger Heavy Infantry Armor's Battery pack, such actions would limit the Armor's usage time with each activation. Developed by Kaiserlich Waffenerbauer in AF 260 (YE 34) to counter this issue, Kaiserlich F&E developed a battery pack to fit over the Armor's battery pack. The Laser Power Module is 60 centimeters in height and width as well as 30 centimeters at its deepest point. With 5 centimeters of protective Durandium Alloy armor, the total dimensions end up being 65x65x35 centimeters.

While designed for the 10mm Infantry Laser Cannon, the Laser Power Module can also power the new LIR-01 Laser Rifle as well. The Laser Power Module can be recharged as the Armor is recharged.

Power consumption of the Laser Power Module's nuclear batteries is listed on a per shot basis.
