Core Advantages


1. DNV-Certified for Maritime Excellence

Every 400V 460Ah solid state battery, 700V 460Ah solid state electrical boat battery, and 1000V 460Ah marine battery meets DNV GL’s strict maritime standards—ensuring reliability in saltwater, extreme vibrations, and harsh weather. This certification is mandatory for commercial vessels, giving operators confidence in compliance and safety.

2. Solid State Safety: No Leaks, No Fires

Unlike liquid electrolyte batteries, our solid state technology eliminates risks of leakage, corrosion, or thermal runaway—critical for enclosed boat compartments. Even if punctured or exposed to seawater, the battery remains stable, protecting crew and cargo.

3. High-Voltage Power for Every Vessel

  • 400V 460Ah: Ideal for small-to-midsize electric boats (10–20m), including fishing boats and leisure yachts. Powers motors up to 300kW with 8+ hours of continuous runtime.

  • 700V 460Ah: Designed for medium commercial vessels (20–40m), such as ferries and workboats. Supports 500–800kW motors with 12+ hours of operation.

  • 1000V 460Ah: Built for large ships (40m+), including passenger ferries and offshore support vessels. Delivers 1000kW+ power with 16+ hours of runtime between charges.

4. Saltwater Resilience & Low Maintenance

IP67 waterproof rating and marine-grade aluminum casing resist corrosion from saltwater, humidity, and UV exposure. No liquid electrolyte means no regular maintenance (e.g., topping up fluids), reducing downtime and operational costs by 40% vs. lead-acid or lithium-ion alternatives.

5. Fast Charging & Smart Integration

Supports DC fast charging: 0–80% in 45 minutes with compatible marine chargers. Integrates seamlessly with boat management systems via CAN bus, allowing real-time monitoring of state-of-charge, temperature, and health via a dashboard or mobile app.


Product Description


Our 400V-1000V 460Ah solid state marine batteries are engineered to replace fossil fuel engines and outdated battery systems with clean, efficient power. Whether you’re retrofitting a commercial ferry or building a cutting-edge electric yacht, these batteries deliver:
  • Range Without Compromise: 184–460kWh capacity ensures all-day operation for most vessels, eliminating the need for mid-journey refueling.

  • Weight Savings: 50% lighter than equivalent lead-acid battery banks, improving boat speed, maneuverability, and fuel efficiency (for hybrid systems).

  • Eco-Friendly Operation: Zero emissions, reducing carbon footprint and complying with strict maritime environmental regulations (e.g., IMO 2020).

The modular design allows easy scaling: connect multiple units to increase capacity for longer voyages or higher power demands. With 6,000+ cycles, these batteries outlast traditional marine batteries by 3–5 times, delivering decades of reliable service.


Application Scenarios


1. Commercial Ferries & Passenger Vessels

The 700V 460Ah solid state electrical boat battery powers 20–40m ferries with 500kW motors, completing 8+ daily trips (30km each) on a single charge. Reduces fuel costs by $150,000+ annually vs. diesel engines.

2. Luxury Yachts & Leisure Boats

The 400V 460Ah solid state battery provides silent, vibration-free power for 10–20m yachts, supporting navigation systems, air conditioning, and entertainment—enhancing passenger comfort while eliminating exhaust fumes.

3. Offshore Workboats & Fishing Vessels
