Product Description

CTS Deep Cycle IP67 Waterproof Marine LiFePO4 Battery 400V 150Ah For Electric Boat Propulsion

As the global marine industry accelerates its transition to clean, quiet and zero-emission electric propulsion, CTS proudly launches the 400V 150Ah Deep Cycle IP67 Waterproof LiFePO4 Marine Battery, professionally engineered for reliable, high-performance power supply in electric boat propulsion, yachts, catamarans and various marine vessels. Built to resist moisture, salt spray, vibration and harsh offshore conditions with IP67 waterproof protection, this battery system delivers stable high-power output and long-lasting deep-cycle performance, effectively extending sailing range and enhancing navigation efficiency. We support professional OEM/ODM customization to match different hull structures, control systems and installation requirements, helping shipyards and boat manufacturers achieve safer, smarter and more eco-friendly electric marine power solutions.

The advantages of our solution:

• 400V High-Voltage Platform: Strong Propulsion & High Efficiency:Designed exclusively for electric boat propulsion, yachts and catamarans, this high-voltage system delivers powerful thrust with lower current, greatly reducing energy loss during navigation. It ensures stable power output, improved cruising efficiency, and consistent performance even under high-speed sailing and heavy-load conditions.

• 150Ah High-Capacity LiFePO4 Cells: Long Cycle Life & Superior Safety:Using premium Grade-A LiFePO4 cells, the battery provides over 6,000 deep cycles and exceptional thermal stability. Its low risk of thermal runaway and high corrosion resistance make it highly reliable for marine environments, ensuring safe long-term operation while lowering total operating costs.

• IP67 Waterproof & Marine-Grade Durability:With an IP67 waterproof and dustproof rating, reinforced enclosure, and salt‑corrosion resistance, the battery withstands moisture, wave impact, vibration and harsh offshore conditions. It maintains stable performance in marine environments and ensures long service life under real‑world sailing conditions.

• Intelligent BMS with Full Protection & Real-Time Monitoring:Built with a professional marine‑grade Battery Management System (BMS), it provides complete protection against overcharge, over-discharge, overcurrent, short circuit, and over/under temperature. Supporting CAN bus communication and remote monitoring, it enables real-time visibility of battery status for safer and smarter navigation.

• Flexible OEM/ODM Customization for Various Vessels:We offer full customization of voltage, capacity, dimensions, connectors and communication protocols to fit different hull structures, propulsion systems and installation layouts. The battery integrates smoothly with electric boats, yachts and work vessels, perfectly matching diverse marine power requirements.
