Product Description
As water transportation and recreational boating shift toward electrification, deep-cycle lithium batteries are becoming the ideal choice for propulsion systems in catamarans, sailboats, and small yachts.
Today, a growing number of vessels — including power catamarans, sailing catamarans, small electric yachts, and day cruisers — are adopting cleaner, quieter, and longer-lasting lithium propulsion.
With professional deep-cycle technology and strong OEM capabilities, CTS Battery provides customized 51.2V LiFePO4 battery solutions for every catamaran, achieving the optimal balance between weight, capacity, and hull layout.
Our solutions are designed to deliver:
· Stable and reliable propulsion power for long cruises
· 3,000+ deep cycles, significantly reducing total cost of ownership
· 1/3 the weight of lead-acid batteries, improving speed and payload
· Modular design to fit catamaran hulls or storage compartments
Whether you are building a new electric catamaran or upgrading an existing sailboat with auxiliary power, CTS helps you build a high-performance, deep-cycle, maintenance-free marine power system.
Advantages of Deep Cycle Marine LiFePO4 Battery
· Designed for Deep Cycle Applications
Catamaran propulsion systems require frequent charging and discharging. Our battery supports 100% depth of discharge (DOD) with over 3,000 cycles — 5 to 8 times longer than lead-acid.
· Lightweight & Compact Design
Over 50% lighter than traditional AGM or gel batteries (e.g., approx. 135kg for 314Ah model), significantly improving hull weight distribution and fuel efficiency (in hybrid scenarios).
· Smart BMS with Comprehensive Protection
Built-in Battery Management System monitors every cell in real time, ensuring:
· Overcharge / over-discharge protection
· Cell balancing and temperature control
· Short circuit and overcurrent protection
· Communication with motor controllers via CAN / RS485
· Flexible Customization for Catamarans
We understand the limited space in catamaran hulls. Therefore we offer:
· Voltage: 12V / 24V / 48V / 51.2V (16S LiFePO4)
· Capacity: 100Ah ~ 600Ah
· Ingress protection: IP65 (standard) / IP67 (optional)
· Size tailored to hull or storage compartments
· Optional low-temperature self-heating for cold waters
· Perfect for Solar / Generator Hybrid Systems
Deep-cycle characteristics make it ideal for solar charging, shore power, and generator backup, enabling green cruising.
