It is a compact cassette power system designed to power EW and RIS systems with the ability for easy and reliable installation on vehicles. The module is equipped with two battery slots, allowing for quick replacement of power elements without losing functionality. Its design is adapted for installation on both military vehicles and medical evacuation (Medevac) vehicles.The module operates on the "hot swap" principle for batteries. The system automatically powers from one battery while the other is in reserve. When the active battery discharges, the Energy Module automatically switches to the second one without power interruption. At this point, the discharged battery is removed and replaced with a charged one, which becomes the new reserve. This ensures continuous power supply even during the physical battery replacement.
