No thermal runaway: Safe by chemistry, not just design
Air-cooled and modular: Simplified, robust integration

Performance and integration

Naval applications demand technology that can operate under extreme conditions, maintain operational readiness, and comply with strict defense safety standards. Echandia’s LTO battery systems are designed for high thermal stability, long life, and mechanical durability, key features for mission-critical vessels that must perform without failure.

The systems support the navy’s broader goals of improving operational efficiency and reducing environmental impact, aligning with defense sector initiatives toward greater sustainability.

We are pleased to secure these important naval orders, which not only show our strong partnership with leading maritime system suppliers but also highlight the trust and confidence placed in our technology.
