Products Photos Catalog Dnv Liquid Cooling Photos Catalog

The IP67 LiFePO4 marine battery system is engineered for electric propulsion, hybrid vessel power, onboard auxiliary loads and marine energy storage applications.

Combining lithium iron phosphate battery technology, an intelligent battery management system, multi-level electrical protection and a sealed IP67 enclosure, the system is designed to deliver stable energy in marine environments exposed to humidity, salt-laden air, vibration, shock and changing operating loads.

The modular battery architecture can be configured according to the vessel’s required voltage, usable energy, propulsion power, charging method, installation space and operating profile.

It is suitable for new electric vessel projects as well as diesel-to-electric and hybrid vessel conversions.
