Smart Digital Hydrophone Battery Pack
Background / Challenge
In ocean monitoring projects, smart digital hydrophones are often deployed far from shore to capture underwater acoustic signals over an extended period. They are used in marine mammal observation, underwater noise assessment for offshore wind farms, vessel noise monitoring, subsea pipeline leakage detection, and protected-area acoustic surveys.
Short-term deployments can usually rely on the built-in battery of the hydrophone. The challenge begins when the system needs to operate independently for long periods on an ocean buoy, seabed lander, or cable-free observation platform.
The customer needed a battery pack that could:
- Match the hydrophone’s 18-36V DC operating range.
- Provide stable power for continuous underwater acoustic observation.
- Fit into an autonomous marine deployment system.
- Support long-term use where frequent battery replacement is difficult.
- Work as an external power source without changing the hydrophone’s core design.
Solution
PKCELL supplied a 22.2V 4400mAh 18650 lithium-ion battery pack as an external standalone power source for the smart digital hydrophone system. The pack voltage is suitable for hydrophone models that operate within an 18-36V DC input range, making it a practical choice for long-duration marine monitoring deployments.
The battery pack can be integrated with hydrophone equipment installed on ocean buoys, seabed landers, or other autonomous observation platforms. By adding an external lithium-ion power supply, the customer can extend field operation time and reduce the need for frequent maintenance trips.
For similar projects, PKCELL can support customization around voltage, capacity, wire length, connector, pack structure, protection requirements, and application-specific assembly needs. Customers developing underwater monitoring systems can also review PKCELL 18650 battery pack solutions for related pack configurations.
