Chariot Defense’s M424 buffers battlefield power, helping soldiers run equipment quietly while the Army speeds procurement and U.S. battery production.
Chariot Defense CEO Adam Warmoth and U.S. Army CTO Alex Miller describe how distributed warfare is straining power systems built around diesel generators and lead-acid batteries. Soldiers’ electronics draw 30–60 watts continuously, while oversized generators can expose positions through heat, noise, and fuel resupply. Chariot’s M424 combines 4 kW of output with 4 kWh of storage; a reconnaissance company ran radios, electronic warfare gear, and drones for 36 hours without detectable thermal or acoustic emissions. The system buffers surges, stabilizes power, and can connect to vehicles, while software could reduce peak demand by staggering loads. Miller outlines acquisition changes that put commercial technology into field exercises faster and reorganize Army procurement around portfolios. He also cites nearly $300 million in battery-manufacturing investment and a further few hundred million under consideration. Their goal: power that works reliably enough for troops to focus on missions, not charging and generators.
