Product Description
The global maritime industry is facing increasing pressure to reduce emissions and adopt electrification. More and more vessels are shifting toward electric or hybrid propulsion systems powered by lithium batteries.
Today, a wide range of marine vessels — including electric yachts, ferries, fishing boats, water taxis, and sailboat auxiliary power — is transitioning to more efficient and environmentally friendly energy systems.
With advanced engineering and strong OEM capabilities, CTS Battery provides customized lithium battery solutions tailored to the specific energy requirements of each marine application.
Our solutions are designed to deliver:
· Reliable power for demanding marine operations
· Extended runtime for long voyages and all-day work
· Improved efficiency and reduced operating costs
Whether you are developing a new electric boat or upgrading an existing vessel, CTS helps you build a high-performance and future-ready marine power system.
Advantages of Marine Lithium Battery
· Built for Harsh Marine Environments
Marine vessels face high humidity, salt spray corrosion, constant vibration, and long operating hours. CTS marine batteries feature IP67 waterproof/dustproof construction, salt-fog resistance, and shock tolerance.
· Lightweight & Compact Design
Up to 50% lighter than lead-acid batteries, improving speed, payload capacity, and reducing hull energy consumption.
Longer runtime per charge, higher overall efficiency.
· Smart BMS Protection System
Built-in Battery Management System monitors every cell in real time, ensuring:
· Overcharge / over-discharge protection
· Temperature control and cell balancing
· Short circuit and overcurrent protection
· Optional low-temperature self-heating function
· Flexible Customization for Your Vessel
We understand that every boat has unique space and power requirements. That’s why we offer:
· Voltage options: 12V / 24V / 48V / 72V / 96V and higher
· Capacity customization: 50Ah ~ 600Ah
· CAN / RS485 communication protocols
· IP65 / IP67 waterproof & dustproof ratings
· Size & structure tailored to hull space
· Better for Smart Navigation & Fleet Management
Electric systems integrate seamlessly with digital technologies such as smart navigation, remote monitoring, and fleet dispatching.
