Battery Systems
Energy and Reliability for Extended Missions

Kraken’s SeaPower is a subsea lithium ion battery featuring a proprietary polymer matrix for pressure-tolerant encapsulation and an integrated Battery Management System (BMS).

This breakthrough in battery encapsulation technology delivers 200% greater energy density and 46% less weight per kWh compared to traditional oil-compensated or pressure-housed subsea batteries.

Its exceptional energy-to-volume and weight ratios enable extended, deeper, and more complex underwater missions.

Unlock Greater Mission Capability

  • Subsea operations shouldn’t be limited by bulky or inefficient power systems.
  • Market-leading energy density extends mission range, endurance, and payload flexibility.

When Mission Success is not Optional

  • Critical missions demand uncompromising safety and performance.
  • Engineered for unwavering reliability where failure is not an option.

Built Around the Mission

  • Your vehicle was designed for a purpose. Your battery should be too.
  • Modular, scalable architecture adapts to your specific power profile.
