Power your vessel with confidence. The E/Strem 52 Blue is a marine-certified, modular battery system engineered for the demands of onboard energy storage — from hybrid ferries and tugboats to fully electric propulsion and offshore support vessels. Built on advanced Lithium Iron Phosphate (LFP) chemistry with liquid cooling and an integrated intelligent BMS, it delivers safe, efficient, high-density energy in a scalable rack-based design that's easy to specify and install on any vessel layout. Made in Europe, it's engineered to keep critical systems running reliably in the harshest marine environments.
Available in three configurations (4, 5, or 6 modules), the E/Strem 52 Blue system scales from 209 kWh to 313 kWh, giving naval architects and shipyards the flexibility to precisely match energy storage to vessel requirements. With certifications spanning DNV, UL 9540, IEC 62619, IEC 63056, UN 38.3, and the EU Battery Regulation 2023/1542, it's built to meet the industry's toughest safety and compliance standards — backed by CAN and Modbus TCP/IP (SunSpec) communications for seamless integration with onboard power management systems.
