1.5 kWh Subsea Battery Bluefin’s 1.5 kWh Subsea Battery is a pressure-tolerant lithium-polymer battery that provides a reliable, high-energydensity 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. 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. Batteries can be rapidly swapped in the field Applications RECHARGEABLE – With the fully automated charging Autonomous Underwater Vehicles (AUVs) system, full battery recharge can be accomplished in Remotely Operated Vehicles (ROVs) six hours or less.
