CTS 51.2V 314Ah Marine LiFePO4 Battery System

Marine LiFePO4 Battery | Deep Cycle Propulsion for Yachts, Catamarans and Electric Boats

The shift toward zero-emission waterways is pushing more vessel owners and builders to adopt electric and hybrid propulsion. Yachts, catamarans, electric speedboats, tour boats, and workboats are all moving to lithium battery power for lower operating costs, quieter rides, and cleaner operation.

CTS Battery now offers a 51.2V 314Ah LiFePO4 marine battery system built specifically for deep cycle marine applications. This lithium ion boat battery delivers reliable propulsion power for electric catamarans and yachts. The same cell platform can scale to higher voltages — 102.4V, 307V, 409V, 512V, and 614V — for larger vessels with higher power demands.

Our marine battery system is designed to deliver:

• Consistent deep cycle performance for long hours on the water
• Lightweight construction for better vessel efficiency
• Safe operation in saltwater and high-humidity environments
• Seamless integration with electric or hybrid drive systems

Whether you are building a new electric catamaran or upgrading an existing yacht to hybrid power, CTS provides a marine-grade power system that works.

• Electric yachts (luxury and cruising)
• Sailing and power catamarans
• Electric speedboats
• Tour boats and passenger vessels
• Fishing boats and workboats
• Research and patrol vessels
• Marine auxiliary energy storage

CTS Battery does not modify light-duty batteries for marine use. Each marine battery pack is built from the ground up with:

• Corrosion-resistant stainless steel housing
• Vibration-tested construction for vessel operation
• BMS logic matched to marine charging sources
• OEM support for electrical and mechanical integration
