[ Sulfurlite™ / Gen II ]
— Battery technology for domestic supply chain RESILIENCE
Power the
unmanned edge.
At Valgotech, we develop and manufacture advanced battery systems for defense and commercial applications, delivering high performance and superior capabilities while ensuring resilience in domestic and non-adversarial supply chains.
Our lithium-sulfur (Sulfurlite™) cell technology and advanced Nickel-Manganese-Cobalt (NMC)-based battery packs (ValgopakTM) are purpose-built for military drones, long-endurance UAVs, satellites, and soldier-worn systems — delivering up to a 45% reduction in weight and a ~30% increase in flight time.
[ Built for mission-critical platforms ]
— MissionEnergy systems for the defense decade.
Modern drones, robotics, and unmanned systems are runtime-bound. Their operators are weight-bound. We build the battery chemistry that breaks both constraints — lighter, safer, and engineered around the realities of the modern battlespace.
— ApplicationsBattery performance that takes mobility farther.
From the warfighter's plate carrier to low Earth orbit, Sulfurlite™ is engineered for the platforms that can't afford to fail.
— TechnologySulfurlite™ — a step-change in energy chemistry.
Our proprietary lithium-sulfur cells and hybrid systems reduce cobalt and nickel use. The result is a battery that is lighter, safer under thermal stress, and free of conflict minerals—engineered for the platforms that define the next decade of defense and aerospace.
