72V (76.8V) 230Ah LiFePO4 Marine Battery: Power Your Voyage with Unmatched Performance


Engineered for the open waters, this marine battery delivers a 17,664Wh (17.6kWh) energy capacity, ensuring extended sailing ranges for electric boats, yachts, and marine vessels. Say goodbye to frequent charging—its high capacity minimizes downtime, letting you stay on the water longer during trips, fishing expeditions, or research missions.


Weighing just 140kg, it's 40% lighter than traditional lead-acid batteries, reducing vessel payload and enhancing fuel efficiency (or electric runtime) while improving speed and maneuverability. The IP67 waterproof/dustproof rating guarantees resilience in harsh marine environments, from heavy waves to saltwater spray, ensuring reliable performance in even the toughest conditions.


Safety is prioritized with an advanced BMS (Battery Management System) that protects against overcharging, overheating, short circuits, and uneven cell discharge. Its intelligent balancing algorithm optimizes cell health, extending the battery's lifespan to 3,000+ charge cycles—3x longer than conventional batteries.


Versatile and robust, this battery powers 5-15kW electric motors for boats, supports marine research platforms, emergency backup systems, and high-performance water sports equipment like electric jet skis. With 98% charge efficiency and rapid recharge capability (0-80% in 3-4 hours via 150A charger), it adapts to demanding schedules. Backed by a 5-year warranty, it's the ultimate marine power solution for reliability, efficiency, and endless adventures on the water.


EA ENERGY 72V (76.8V) 230Ah LiFePO4 Lithium Battery is engineered for next-generation marine propulsion systems, delivering unmatched energy density and durability for premium electric vessels like Navier, Foilone, Candela, and Silent yachts. With a high-capacity 230Ah rating and stable 76.8V nominal voltage, this battery optimizes performance for 20-50kW motor setups, enabling extended cruising ranges and rapid acceleration for electric boats, hydrofoils, and luxury speedboats. Designed for eco-conscious maritime applications, it provides reliable power for commercial water taxis, private yachts, and high-speed watercraft while supporting auxiliary systems like navigation and emergency lighting. Its advanced LiFePO4 chemistry ensures exceptional thermal stability, rapid charging capability, and a 3000+ cycle lifespan, making it a zero-emission powerhouse for sustainable aquatic mobility.
