CTS 51.2V 102.4V 307V 314Ah Long Life Cycle IP67 LiFePO4 Electric Marine Propulsion Battery System For Catamaran
High-Voltage Marine LiFePO4 Batteries
Driven by tightening global maritime environmental regulations and accelerating zero-carbon shipping targets, high-voltage LiFePO4 lithium batteries are at the heart of the transformation toward electric and hybrid marine vessels.
A wide range of marine applications including catamarans, luxury yachts, sightseeing boats, commercial fishing vessels, recreational sailboats, and workboats are transitioning to more efficient, eco-friendly electric and hybrid propulsion systems.
Consistent, high-power output for heavy-duty marine operations in harsh conditions
Extended runtime for long voyages, significantly increasing vessel range
Improved system efficiency and reduced total operational costs
IP67-rated protection with superior waterproof, dustproof, and corrosion-resistant performance
Zero exhaust emissions and low-noise operation for sustainable marine applications
Advantages of Marine Lithium Battery
Built for Demanding Marine Applications
Engineered to withstand salt spray corrosion, high humidity, strong vibration, extreme temperature fluctuations, and long continuous operating hours, ensuring reliable performance in tough ocean conditions.
Lightweight & Compact Design
Up to 50% lighter than traditional lead-acid batteries, reducing vessel weight and improving energy efficiency while saving valuable onboard space.
Smart BMS Protection & Monitoring System
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 vessel control system integration
Optional liquid cooling/heating thermal management systems
Long Cycle Life & Superior Safety
Using Grade A LiFePO4 cells with a cycle life of over 6000 times and 10-year design life. The inherently stable LiFePO4 chemistry eliminates thermal runaway risk for enhanced marine operation safety.
