Core Advantages of Battery for Special Underwater Vehicle

1. Underwater-Engineered Sealing & Durability

“The Battery for Special Underwater Vehicle features IP68-rated sealing and pressure-resistant casing:
  • Withstands underwater pressure up to 50m (tested), ensuring no leakage or short-circuits during submersible operations.
  • Corrosion-resistant materials protect against saltwater and marine debris, ideal for long-term underwater deployment.”

2. RS485-Driven Smart Underwater Fleet Management

“Integrated RS485 communication enables:
  • Real-time transmission of battery SOC, temperature, and discharge data to underwater vehicle control systems.
  • Customizable alerts for overcurrent, low voltage, or overheating—critical for preventing mission failure in deep-water environments.”

3. Wide Temperature & High Discharge Performance

“Designed for extreme marine climates:
  • -20~60℃ Operation Range: Powers vehicles in icy arctic submersions (-20℃) and tropical marine exploration (60℃), with no capacity loss.
  • 50A Continuous Discharge: Supports high-power thrusters, sonar systems, and underwater lighting in submersible vehicles.”

Application Scenarios

1. Underwater Robots for Marine Research

“Scientific Exploration: Powers ROVs (Remotely Operated Vehicles) conducting seabed mapping, marine life observation, and wreck inspection. The Battery for Special Underwater Vehicle’s 50Ah capacity and RS485 enable 8+ hours of continuous research missions with real-time battery health tracking.”

2. Submersible Vehicles for Industrial Maintenance

“Underwater Infrastructure Inspection: Supplies energy for submersible vehicles inspecting pipelines, dams, and offshore structures. Its 50A discharge handles simultaneous operation of inspection cameras, robotic arms, and propulsion systems—ensuring efficient maintenance workflows.”

3. Military & Defense Submersible Systems

“Tactical Underwater Operations: Powers specialized submersible vehicles for surveillance, mine detection, and covert missions. The battery’s wide temperature tolerance and rugged design ensure reliability in hostile marine environments.”
