Custom Underwater Battery Packs for Oceanographic Systems
Our custom battery systems are engineered specifically for marine and underwater equipment. Drawing on decades of experience, we deliver high-reliability AUV batteries, underwater batteries, sea-water battery packs, and ocean battery systems for extended field deployments. Each solution is built to withstand deep-sea conditions — rugged pressure housings, robust connectors and high-capacity cells ensure years of service without maintenance. We specialize in large-format cylindrical packs (even up to 10 ft long) assembled on custom tooling, so we can meet virtually any size or form-factor requirement.

Client Success Stories
Proven engineering solutions for critical subsea environments.
Ocean Bottom Node (OBN) Battery Project
- High-Precision Seafloor Seismic Technology
The client faced critical failure risks due to water leakage in battery compartments under high hydrostatic pressure (700m depth), compromising expensive seismic data collection.
We engineered a dual-layer protection system. Beyond the standard cell assembly, we designed a bespoke vacuum-sealed enclosure and reinforced the OBN shell structure. This value-added service ensured zero leakage and reliable power delivery at operational depths.
Next-Gen Defense Underwater Power
- Defense & Security (UUVs, Beacons)
The defense client required significantly higher energy density and extended cycle life for underwater vehicles and beacons, but was strictly limited by a compact battery footprint.
We implemented cutting-edge Semi-Solid State Technology. This innovation maximized energy density within the restricted space while enhancing safety. The final design successfully passed 18 rigorous safety tests required for military-grade deployment.
