High Performance 12.8V 690Ah Marine LiFePO4 Battery For Marine Yachts Boats
 

Marine LiFePO4 Battery engineered for offshore and on-water use. Unlike smaller marine batteries or outdated lead-acid alternatives, this Marine LiFePO4 Battery leverages Lithium Iron Phosphate (LiFePO4) chemistry to deliver a massive 8832Wh of energy—enough to power a yacht’s navigation systems, refrigeration, lighting, and even auxiliary motors for days without recharging. What sets this Marine LiFePO4 Battery apart is its ability to handle extreme marine conditions: IP65 saltwater resistance, -20℃~60℃ temperature adaptability, and 300A continuous discharge for high-demand equipment. Every feature—from its CAN communication to M8 marine-grade terminals—is tailored to solve the unique challenges of boating, making it the most trusted Marine LiFePO4 Battery for serious boaters and commercial operators.

Specifications

This isn’t just a high-capacity battery—it’s a purpose-built Marine LiFePO4 Battery that addresses the biggest pain points of marine power: limited runtime, vulnerability to saltwater, frequent maintenance, and inability to handle heavy loads. Here’s how this Marine LiFePO4 Battery outperforms traditional marine batteries:
8832Wh Massive Energy: Powers Large Vessels for Extended Trips
Unlike smaller Marine LiFePO4 Battery options (e.g., 100~300Ah models), this Marine LiFePO4 Battery delivers 8832Wh of energy—enough to run a 50-foot yacht’s essential systems (GPS, VHF radio, 12V fridge, and LED lighting) for 3~4 days of offshore cruising. For commercial 渔船,it can power fish finders, bait tanks, and deck lights through 12-hour shifts without needing a recharge. This extended runtime eliminates the stress of “range anxiety” on the water, making this Marine LiFePO4 Battery ideal for long-distance boating or remote fishing expeditions.
4000+ Cycles: A Marine LiFePO4 Battery That Lasts for Years
Traditional lead-acid marine batteries last just 300~500 cycles (1~2 boating seasons), but this Marine LiFePO4 Battery delivers over 4000 cycles (at 1C, 80% DOD) with remaining capacity >80%—that’s 8~10 years of reliable use. For boat owners, this means fewer battery replacements (a costly and labor-intensive task on water) and lower long-term costs. Even with frequent use (e.g., weekly yacht trips or daily commercial fishing), this Marine LiFePO4 Battery maintains peak performance, making it a cost-effective investment for any boat.

300A Continuous Discharge: Handles Heavy Marine Loads
Large boats often require power for high-demand equipment—auxiliary motors, hydraulic winches, or large refrigeration units—and this Marine LiFePO4 Battery is built to deliver. It supports 300A continuous discharge current (enough to run a 3HP auxiliary motor) and 500A pulse discharge current (<10S) for short bursts (e.g., starting a small inboard engine or lifting a heavy anchor with a winch). Unlike lead-acid batteries that drop voltage under load (causing equipment to stall), this Marine LiFePO4 Battery maintains stable 12.8V output, protecting sensitive marine electronics and ensuring smooth operation.
IP65 Saltwater Resistance: Built for Harsh Marine Environments
Saltwater, humidity, and spray are the biggest enemies of marine batteries—but this Marine LiFePO4 Battery is designed to withstand them. Its ABS housing features an IP65 rating, meaning it’s fully dustproof and resistant to low-pressure water jets (critical for deck-mounted or bilge-installed batteries). The housing also includes anti-corrosion coatings to prevent saltwater damage, while the M8 marine-grade terminals (plated with nickel) resist rust and ensure secure connections even in damp conditions. This durability makes this Marine LiFePO4 Battery suitable for saltwater boating, unlike unprotected batteries that corrode quickly.
CAN Communication: Smart Monitoring for Marine Safety
Safety is paramount on water, and this Marine LiFePO4 Battery includes CAN communication to integrate with your boat’s existing monitoring system. You can track State of Charge (SOC), voltage, current, and temperature in real time via the boat’s dashboard or a mobile app—no need to manually check the battery (a risky task in rough seas). The integrated BMS (Battery Management System) adds layers of protection: short-circuit protection (300~800us response), overcharging (14.8V cut-off), over-discharging (10V cut-off), and high-temperature cut-off (65℃). These features ensure the Marine LiFePO4 Battery and your boat’s electrical system stay safe, even in unpredictable conditions.

Ideal Applications: Which Boats Benefit Most from This Marine LiFePO4 Battery?
This Marine LiFePO4 Battery is engineered for medium-to-large boats that need high capacity, durability, and power—here’s where it excels:
Leisure Yachts & Cruisers: Powers 40~60-foot yachts’ navigation systems, cabins, refrigeration, and auxiliary motors during weekend or week-long trips. The 8832Wh capacity ensures no mid-trip power shortages, while CAN monitoring lets captains track battery status easily.
Commercial Fishing Vessels: Runs fish finders, bait tanks, deck lights, and small winches for 12-hour fishing shifts. IP65 saltwater resistance withstands daily spray, and 4000+ cycles reduce replacement costs for commercial operators.
Workboats & Patrol Vessels: Supports law enforcement patrol boats, rescue vessels, or survey boats that need reliable power for radios, radar, and emergency lights. The 300A discharge handles auxiliary motors, while modular expansion adapts to 48V systems.
