Echandia Robust

Our most enduring battery system

Engineered for reliability and safety

Echandia Robust is built for operators who cannot afford failure. It’s our safest, most durable battery system, engineered for extreme reliability, long lifetime, and true heavy-duty performance. While designed as a commercial solution, its safety and durability are validated to the highest standard, and NATO has selected it for military use.

It is an air-cooled lithium-ion energy storage system, certified for maritime heavy-duty operations and based on lithium-titanium-oxide (LTO) technology.

Inherent Safety

Removes the possibility of thermal propagation, ensuring maximum operational safety.

Extreme Durability

Designed for the harshest conditions and long service life.

Mechanical Robustness

Engineered to withstand shock, vibration and high mechanical stress.

Built-In Redundancy

Backup systems across critical functions ensure uninterrupted, reliable power.

Robust by design: built for mission-critical use

Echandia Robust maintains performance under shock, vibration, rapid cycling, and extreme loads, which is exactly why military organizations choose it. Every component is selected for long life, reliability, and resilience.

Commercial system, military-grade performance

Although it’s available as a standard commercial product, Echandia Robust delivers the safety, stability, and endurance required in defense and security operations. No customization needed, the durability is built in.

Two configurations

Power

High power for short cycles

For vessels that need instant power, repeatedly. Tailored for operations requiring high power output and frequent cycling more than seven cycles per day.

Applications

Spinning reserve
Peak shaving
Load leveling
Black-out prevention
Full electric propulsion

Performance
Current rating per string 500 / 500 A
Continuous 24 h operation max RMS current per string 100 A
