CTS Deep Cycle 51.2V 314Ah Boat Lithium Battery for Catamaran Propulsion

 Product Description

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.

 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. 192.8kWh energy storage (higher options available) 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 / 614V and custom
  · Capacity customization: 100Ah – 400Ah
  · Liquid cooling (standard) and liquid heating (optional)
  · CAN / RS485 communication protocols
  · IP67 or 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
