Bluefin 1.5 kWh Subsea Battery
The Bluefin® 1.5 kWh Subsea Battery is a pressure-tolerant lithium-polymer battery that provides a reliable, high-energy density power solution for underwater systems. The battery electronics include built-in protection, monitoring, power control, and battery conditioning. Leveraging over a decade of battery development and with hundreds of units in the field, the 1.5 kWh Subsea Battery has demonstrated utility across a variety of underwater applications, including:
- Autonomous Unmanned Underwater Vehicles (UUVs)
- Remotely Operated Vehicles (ROVs)
- Profilers
- Buoys
- Submersible Systems
Features
FULLY SUBMERSIBLE
The 1.5 kWh Subsea Battery is designed for direct submergence in water in any orientation, eliminating the need for a pressure vessel.
HIGH ENERGY DENSITY
The lithium-polymer chemistry provides extremely high energy density while still maintaining good cycle life and performance, which are desirable for subsea applications.
SWAPPABLE
The design of the 1.5 kWh Subsea Battery allows a user to quickly replace a discharged battery with a charged one without ever opening a pressure vessel. This enables rapid turnaround of submersible equipment in the field.
RECHARGEABLE
With the fully automated charging system, full battery recharge can be accomplished in six hours or less.
OTHER FEATURES
- Rechargeable lithium-polymer cells
