Universal Battery Charger (UBC) Gen 4

The UBC GEN 4 combines the functions and capabilities of multiple battery chargers into one small, scalable package. It provides battery-charging technology to the warfighter through a highly rugged, field-deployable, multi-battery modular solution for austere mission environments.

The UBC GEN 4 charging system charges a wide range of military and commercial batteries, and provides for the addition of new batteries through software upgradability and an innovative modular design. The base unit weighs approximately six pounds, is small enough to be carried in a rucksack, and is rugged enough to be vehicle mounted. Multiple UBC charging systems can be cascaded and powered from a single power source without requiring any tools. The UBC allows charging under heavy rain, and in other harsh environmental conditions, without cover. The charger is optimized to provide the warfighter with the ability to harvest power from solar panels, and a variety of other power sources.
