About SeaPower Batteries
SeaPower uses polymer-matrix encapsulation to protect lithium-ion cells directly against subsea pressure. The architecture removes pressure vessels and oil compensation and incorporates a battery-management system across the module and pack.
Systems scale from 1.8 kilowatt-hours to five megawatt-hours and can be pressure tested to 6,000-metre depth. Kraken configures packs for small AUVs, work-class vehicles and XLUUVs and supplies chargers, power-management units and integration hardware. The company reports twice the energy density and 46% lower weight per kilowatt-hour than traditional subsea batteries.

2025-04-10 - Commercial Order - The orders were driven predominantly by defence-industry UUV demand. Kraken described SeaPower as pressure tolerant to 660 bar, equivalent to 6,000 metres ocean depth. The company was expanding manufacturing capacity and developing smaller form factors for small and medium UUVs.
