CTS 96V 200Ah 300Ah 400Ah 20kWh 30kWh 40kWh LiFePO4 Marine Lithium Battery Solution IP67 Waterproof For Catamaran and boat

Driven by tightening global maritime environmental regulations, accelerating zero-carbon shipping targets, and the surging demand for low-noise, low-maintenance, and long-range power systems in both recreational and commercial marine sectors, the shift toward electric and hybrid marine vessels is gaining unprecedented momentum and high-voltage LiFePO4 lithium batteries are at the heart of this transformation.
Today, a wide range of marine applications — including catamarans, luxury yachts, sightseeing boats, commercial fishing vessels, recreational sailboats, and workboats — are transitioning from traditional fossil fuel power to more efficient, eco-friendly electric and hybrid propulsion systems. This shift not only helps meet increasingly strict emission standards but also significantly reduces operational costs and enhances the overall sailing experience.
With advanced engineering and strong OEM capabilities, CTS Battery provides customized lithium battery solutions tailored to the specific energy requirements of each application.
Our marine-grade high-voltage lithium battery solutions are designed to deliver:

• Consistent, high-power output for heavy-duty marine operations, performing reliably even in harsh conditions such as rough seas, humidity, and salt spray
• Extended runtime for long voyages, significantly increasing the vessel’s range and reducing the need for frequent recharging or refueling
• Improved system efficiency and reduced total operational costs, including lower fuel expenses, minimal maintenance requirements, and a longer service life
• IP67-rated protection with superior waterproof, dustproof, and corrosion-resistant performance, perfectly suited to the demanding marine environment
• Zero exhaust emissions and low-noise operation, offering a cleaner, greener power alternative for sustainable marine applications

Whether you are developing new electric marine vessels, upgrading existing yachts with hybrid propulsion systems, or replacing outdated lead-acid batteries on fishing boats, CTS helps you build a high-performance, future-ready marine power system that meets global maritime environmental standards and keeps your marine business competitive in the evolving market.

Marine vessels operate in harsh environments — including salt spray corrosion, high humidity, strong vibration, extreme temperature fluctuations, and long continuous operating hours. CTS marine lithium batteries are engineered to withstand these challenges, ensuring consistent, reliable performance even in the toughest ocean conditions.

Up to 50% lighter than traditional lead-acid batteries, our LiFePO4 packs reduce vessel weight and improve overall energy efficiency, while saving valuable onboard space for design flexibility. With high energy density, they deliver longer runtime to support extended voyages and operations.

•  Overcharge / over-discharge protection
•  Overcurrent / short circuit protection
•  Temperature monitoring and control
•  Cell balancing and health management
•  Real-time data monitoring and online alarm
•  Optional CAN / RS485 communication for seamless integration with vessel control system

We understand that marine applications vary widely across catamarans, yachts, sightseeing boats, and fishing vessels. That’s why we offer fully customizable solutions tailored to your unique requirements:

•  Capacity customization: 200Ah / 400Ah Or others
•  Communication protocols: CAN / RS485 optional
•  Waterproof & dustproof design: IP65 / IP67 ratings for marine environments
•  Corrosion-resistant options: 304 / 316 stainless steel cases for saltwater resistance
•  Custom size & structure to fit your vessel’s installation space
•  Optional liquid cooling/heating thermal management systems for extreme temperature conditions

Using Grade A LiFePO4 cells, our marine batteries feature a cycle life of over 6000 times and a 10-year design life, significantly reducing long-term maintenance and replacement costs. The inherently stable LiFePO4 chemistry eliminates the risk of thermal runaway, delivering enhanced safety for marine operations.

•  Electric Catamarans: Optimized weight distribution for multi-hull stability.
•  Luxury Yachts: Experience silent cruising without the noise and fumes of diesel generators.
•  Commercial Sightseeing Boats: High energy density for extended daily tour operations.
•  Professional Fishing Vessels: Reliable power for propulsion and heavy-duty onboard equipment.
