CTS 51.2V 314Ah 16kWh LiFePO4 Marine Battery for Electric Catamaran and Yacht
Marine High Voltage Lithium Battery
A smarter, cleaner, more reliable power solution for vessels. The global marine industry is accelerating the shift to electrification. Catamarans, yachts and sailboats have rapidly growing demand for high voltage marine batteries.
Compared to traditional lead acid batteries, LiFePO4 batteries offer lighter weight, longer cycle life and higher safety.
CTS Battery introduces the 51.2V 314Ah 16.07kWh LiFePO4 marine battery with 1P16S cell configuration, designed specifically for electric catamarans, yachts and electric boats.
Whether you are an OEM shipyard developing new electric vessels or a boat owner planning to retrofit existing boats to electric propulsion, CTS provides customized lithium battery solutions tailored to your needs.
Performance & Future-Ready Power System
51.2V High Voltage Platform: Lower current, less heat, higher efficiency
16.07kWh Energy Reserve: Full day cruising for catamarans and yachts
1P16S Cell Configuration: 314Ah single cell, no parallel connection, better consistency
300A Continuous / 560A Peak Discharge: Handles sudden acceleration and heavy load
140A Max Charging: Fast recharge, less dock waiting time
Smart BMS + CAN: Full protection against overcharge, over discharge, over temperature, short circuit - real time communication with motor controller
Built-in PI Heating Film + Liquid Cooling Plate: Low temp preheating, high temp active cooling
The Advantages of CTS Marine LiFePO4 Battery
IP67 Waterproof & Salt Spray Proof: Fully sealed design with IP67 protection rating. Lower case in aluminum alloy, upper cover in stainless steel for dual corrosion resistance.
High Capacity 314Ah with 1P16S No Parallel: 314Ah prismatic LiFePO4 cells in 1P16S configuration (16 series, no parallel). No parallel means no circulating current risk, better cell consistency, higher reliability.
High Rate Charge and Discharge: Supports 300A continuous discharge, 560A peak discharge for 30 seconds. Handles yacht sudden acceleration and catamaran heavy load. Supports 140A fast charging, significantly reduces dock time.
Wide Temperature Range with Smart Thermal Management: Built-in PI heating film preheats cells before charging in low temperature. Built-in liquid cooling plate actively cools during high current discharge. Maintains optimal operating temperature.
Lightweight with High Strength Design: Weight approximately 110kg, much lighter than lead acid. Aluminum alloy lower case reduces weight. Stainless steel upper cover improves strength.
Year Warranty + Technical Support: CTS provides a 2 year standard warranty and technical support on all battery systems for peace of mind.
Applications
The CTS 51.2V 314Ah Marine Battery is suitable for the following electric vessel applications:
Built-in PI Heating Film, Built-in Liquid Cooling Plate
