The company plans to use the funds to accelerate production of its power system products and to develop an operating system to manage and distribute electric power on the battlefield.
Chariot Defence, a defence technology company developing advanced battlefield power systems, sees power as a key limit in military operations. To address this, they created a deployable, software-controlled power system that senses, prioritises, and directs power to critical systems in real time, allowing soldiers to operate without downtime, excess energy use, or detectable signals.
Modern operations often fail due to power shortages. Chariot’s versatile Amphora hybrid power systems boost warfighter effectiveness and safety by combining energy storage, conversion, and distribution to deliver power exactly when and where it’s needed. Units are already using these systems to remain operational longer and adapt to distributed, expeditionary missions with reliable, continuous power. Chariot has sold Amphora systems directly to customers, including commercial clients who value power to drive innovation and strengthen their deployments.
“We aim to make sure power is never a limit in modern warfare,” said Adam Warmoth, Chariot Defence Founder and CEO. “Battlefield power isn’t just about how much energy you carry—it’s about controlling and distributing it smartly. Chariot’s Amphora systems give soldiers more freedom, helping them see, sense, strike, and survive in tough environments. The rapid adoption of our systems shows the strength of our technology and team. We’re already using this funding to expand and meet growing demand.”
“Major advances in power are happening in the commercial world—like better batteries and new power electronics—while much of defence still uses old systems,” said Erin Price-Wright, General Partner at Andreessen Horowitz. “Chariot is bringing this innovation to national security, creating the software-defined power systems today’s military needs. The future of defence will depend on energy, speed, and flexibility, and Chariot is leading the way.”
“We’re excited to support Chariot again,” said Ross Fubini, Managing Partner at XYZ Venture Capital. “They’ve applied an Anduril-style approach, getting systems into the field early and improving key features quickly. With demand for fast deployment higher than ever, Chariot is a clear example of field-ready innovation.”
Warmoth added, “Chariot went from seed funding to deploying equipment in exercises within six months and started generating revenue in a year. This rapid progress is why we’re growing so quickly.”
The company is looking for mechanical, electrical, and software engineers skilled in high-voltage energy storage, power electronics, and distributed systems to help build the power systems shaping modern military operations.
