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.
• 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 enclosure, and vibration-resistant structure.
• Lightweight & High Energy Density
Up to 50% lighter than traditional lead-acid batteries, significantly improving vessel efficiency and payload capacity.
• 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 / 500V / 600V
Capacity customization: 100Ah – 300Ah
Liquid cooling (optional)
CAN / RS485 communication protocols
IP67 / higher protection levels
Size and structure tailored to vessel layout
Seamless Integration with Hybrid/Electric Propulsion
The high-voltage system supports fast charging and integrates easily with marine inverters, motors, and energy management systems — perfect for both new builds and retrofits.
