Both companies will conduct joint technical evaluations and testing to assess the compatibility of Li-S Energy’s high-energy-density cells with Praetorian’s interceptor drones and airborne systems. Commercial outcomes will be determined based on the results of these programs, with the agreement providing a framework for potential future integration and expansion into broader applications.
The collaboration reflects a shared focus on strengthening Australia’s sovereign defence capability through the combination of Li-S Energy’s advanced battery innovation and Praetorian’s autonomous unmanned aerial systems. The partnership supports the development of dual-use technologies that can be applied to both civilian and military domains.
Dr. Lee Finniear, Managing Director of Li-S Energy, said: “We are excited to collaborate with Praetorian Aeronautics, one of Australia’s most innovative defence technology companies. This partnership provides a pathway to allow us to demonstrate the real-world advantages of our advanced batteries in demanding operational environments where size, weight and performance are critical.”
Dr. Finniear added: “Praetorian’s plans to build up to 10,000 Dagger interceptor drones per year in Australia offers LIS a significant pathway toward commercial sales, while the combination of our two technologies delivers a substantial leap forward in sovereign defence manufacturing capability.”
Praetorian Aeronautics, based in South Australia, develops AI-driven systems such as the Dagger counter-UAV interceptor drone and the Hadrian battle management platform. Both systems are designed and produced domestically to enhance national security and rapid-response capability in multi-domain environments.
Brett Hill, CEO and Founder of Praetorian Aeronautics, said: “Batteries are a defining constraint in the performance envelope of modern UAS platforms. Working with Li-S Energy enables us to explore the use of advanced Australian battery technology that could offer greater range, reduced weight and improved payload capacity – directly supporting the operational goals of our Dagger and Hadrian systems.”
He added: “An important factor in choosing Li-S Energy was its proven ability to manufacture battery cells here in Australia. We are proud to be working with another Australian company to deliver innovation that enhances national security and supports local industry.”
The collaboration highlights growing interest from both domestic and international defence organisations in Li-S Energy’s technology. By advancing high-performance battery and autonomous systems integration, the partnership aligns with Australia’s strategic goal of building resilient, sovereign industrial capabilities in defence and advanced manufacturing.
