Every feature—from CAN communication to M8 marine‑grade terminals—is tailored to solve the unique challenges of boating, making this Marine LiFePO4 Battery the trusted choice for serious boaters and commercial operators.

Specifications

Core Specifications of This Marine LiFePO4 Battery
Nominal voltage is 12.8V with 690Ah rated capacity and total energy of 8832Wh. Internal resistance is ≤50 milliohms. Efficiency reaches 98 percent. Self discharge is less than 5 percent per month. This Marine LiFePO4 Battery delivers over 4000 cycles at 1C and 80% DOD while retaining over 80 percent of original capacity. Cell configuration is 4S3P. Dimensions are 742mm by 241mm by 308mm. Weight is 56 kilograms. Terminal type is M8. Housing is ABS with IP65 protection. This Marine LiFePO4 Battery includes CAN communication for smart monitoring.

Discharge Performance of This Marine LiFePO4 Battery
Continuous discharge current is 300 amps, enough to run a 3HP auxiliary motor or multiple high‑demand systems. Pulse discharge current reaches 500 amps for less than 10 seconds, handling short bursts such as starting an inboard engine or lifting an anchor. This Marine LiFePO4 Battery maintains stable 12.8V output under heavy loads, protecting sensitive marine electronics. BMS discharge cut‑off is 10V with reconnect at 10.8V. Short circuit protection activates within 300‑800µs.

Charge Parameters for This Marine LiFePO4 Battery
Charging uses CC‑CV with voltage range 14.2‑14.6V. Recommended float voltage at full charge is 13.3‑13.4V. Maximum charge current is 300A for fast recharging. BMS charge cut‑off is 14.8V. This Marine LiFePO4 Battery accepts high‑current charging to minimize downtime between trips.

Cycle Life and Longevity—Why This Marine LiFePO4 Battery Lasts
Rated for over 4000 cycles, this Marine LiFePO4 Battery provides 8‑10 years of reliable use—far outlasting lead‑acid batteries that last only 300‑500 cycles. For boat owners, this Marine LiFePO4 Battery means fewer replacements and lower long‑term costs. Even with weekly yacht trips or daily commercial fishing, this Marine LiFePO4 Battery maintains peak performance.

Temperature Range and Durability
This Marine LiFePO4 Battery discharges from -20°C to 60°C and charges from 0°C to 55°C. Storage range is -20°C to 60°C. BMS high‑temperature cut‑off is 65°C. The IP65‑rated ABS housing with anti‑corrosion coatings makes this Marine LiFePO4 Battery resistant to saltwater spray and humidity, ensuring reliable operation in harsh marine environments.

Marine‑Specific Benefits of This Marine LiFePO4 Battery
This Marine LiFePO4 Battery solves the biggest points of marine power. Its 8832Wh capacity powers a 50‑foot yacht's essential systems—GPS, VHF radio, 12V fridge, LED lighting—for 3‑4 days of offshore cruising. For commercial fishing vessels, this Marine LiFePO4 Battery runs fish finders, bait tanks, and deck lights through 12‑hour shifts. The M8 nickel‑plated terminals resist rust, and the integrated BMS provides overcharge (14.8V cut‑off), over‑discharge (10V cut‑off), and short‑circuit protection. CAN communication lets you track SOC, voltage, current, and temperature from the dashboard, making this Marine LiFePO4 Battery as smart as it is powerful.
