Our safest and most robust battery system

Echandia Robust

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 so proven that 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.

Designed for absolute safety

This system is available to all our customers, a commercial platform trusted at the highest operational level. Echandia Robust is built from the ground up to eliminate risk, not just manage it.

Intrinsic safety

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

Extreme Durability

Designed to withstand the harshest conditions and continuous, long-term operation.

Mechanical Robustness

Exceptional shock resistance and structural integrity in high-stress environments.

Built-In Redundancy

Redundancy in every critical function ensures uninterrupted, reliable power—certified and proven for demanding maritime environment.

Robust by design – built for mission-critical use

The system maintains performance under shock, vibration, rapid cycling, and extreme loads, 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.

Long life. High performance. Zero compromise.

Longer life

20+ years of service life

High cycles

30,000+ cycles with minimal degradation

Fast charge

Fast charging for high operational availability

Modular design

Modular, easy-to-install architecture

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). Ideal for hybrid marine propulsion applications needing short bursts of power.

Applications

  • Spinning reserve
  • Peak shaving
  • Load leveling
  • UPS
  • And other high-power
  • Short-duration demands

Performance

Peak max current per string (Discharge / Charge)
550 A / 550 A for 100 s

Continuous max current per string (Discharge / Charge)
400 A / 400 A for 300 s, 160 A / 160 A > 300 s

Life-time 2C Discharge / Charge to 80% EOL
70 000 cycles at 50% DoD

Usable capacity (% of installed)
90% (5% - 95% SOC)

Weight
Example: 4770 kg for 274 kWh @ 1000 Vmax

Energy

High energy for long cycles

For operations that require sustained output and long life. Designed for applications where energy storage capacity is more critical than power output, with fewer cycles per day (seven or less). It offers cost efficiency for long-duration operations and represents a durable solution for advanced energy storage.

Applications

  • Full electric propulsion
  • High-energy demand operations
