Product Description

Marine LiFePO4 Battery | High-Voltage Propulsion for Yachts and Catamarans

The global shift toward green shipping and zero-emission waterways is accelerating the adoption of electric and hybrid propulsion systems for yachts, catamarans, and commercial vessels.
Today, a growing number of marine applications — including luxury yachts, sailing catamarans, electric speedboats, tour boats, and workboats — are transitioning to cleaner, quieter, and more efficient lithium battery power.
With advanced marine-grade engineering and strong OEM capabilities, CTS Battery provides customized high-voltage lithium battery solutions tailored to the specific energy and space requirements of each vessel.
Our solutions are designed to deliver:

· Reliable propulsion power for long-distance cruising
· High energy density with reduced weight
· Safe operation in saltwater and harsh marine conditions
· Seamless integration with hybrid or fully electric drive systems

Whether you are building a new electric catamaran or upgrading an existing yacht to hybrid power, CTS helps you build a safe, high-performance, and future-ready marine power system.

The Advantages of Marine LiFePO4 Battery

Built for Harsh Marine Environments

Marine vessels face saltwater corrosion, constant vibration, humidity, and long operating hours. Our high-voltage battery pack is engineered with IP67 waterproof and dustproof housing, stainless steel 316 enclosure, and vibration-resistant construction to withstand the toughest conditions at sea.

Lightweight & High Energy Density

Up to 50% lighter than traditional lead-acid batteries, significantly improving vessel efficiency and payload capacity. The 120kWh energy storage provides extended cruising range, while the compact modular design saves valuable onboard space.

Smart BMS with Advanced Protection

Built-in intelligent Battery Management System ensures:

· Overcharge / over-discharge protection
· Cell balancing and temperature control
· Short circuit and overcurrent protection
· Real-time SOC monitoring via CAN / RS485

Flexible Customization for Your Vessel

We understand that every yacht and catamaran has unique power requirements. That’s why we offer:

· Voltage options: 300V / 400V / 530V / 600V and custom
· Capacity customization: 100Ah – 300Ah
· Liquid cooling (standard) and liquid heating (optional)
· CAN / RS485 communication protocols
· IP67 / higher IP ratings upon request
· Size and structure tailored to vessel layout

Applications

· Luxury Yachts (electric & hybrid propulsion)
· Sailing and Power Catamarans
· Electric Speedboats
· Tour Boats and Passenger Vessels
· Fishing Boats and Workboats
· Research and Patrol Vessels
· Marine Auxiliary Energy Storage Systems
