Power systems built to go deep.
Custom Li-ion battery packs and BMS engineered for marine and underwater platforms — sealed, pressure-tolerant, corrosion-resistant power systems for ROVs, AUVs, and surface vessels.
Why Marine Programs Choose Custom
Engineered for an environment with no room for error.
Underwater and marine platforms face a uniquely unforgiving environment — pressure, salt, and zero tolerance for ingress. A battery failure isn't a quick fix when it's at the bottom of the ocean.
Pressure tolerance
Pack architecture and enclosure design engineered to withstand sustained pressure at operating depth, without compromising energy density.
Ingress protection
Sealed enclosures and connector systems built to keep saltwater out completely — a single leak point is a mission-ending failure.
Corrosion resistance
Materials and coatings selected for long-term exposure to saltwater and humidity, protecting both the pack and its connectors.
Endurance for long missions
Survey and inspection missions run long and remote — energy density and efficient power management directly extend usable mission range.
What We Offer
Power systems for marine & underwater platforms.
From sealed custom packs to the monitoring systems that keep missions safe.
Custom battery packs
NMC and LFP Li-ion packs designed around your vehicle's pressure housing, voltage, and capacity requirements for ROV and AUV platforms.
Pressure-rated enclosures
Battery housings engineered for sustained underwater pressure at depth, with sealed connector systems built to prevent ingress.
Battery management systems
Protection and intelligent control engineered for the thermal and pressure conditions of underwater operation.
Surface vessel power systems
Battery and power management solutions for autonomous surface vessels and support craft.
(in development)Monitoring & telemetry
On-board diagnostics for mission-critical state-of-health monitoring, where surfacing to check a battery isn't always an option.
Dock & shore charging
Charging infrastructure for vehicle recovery and turnaround between missions.
(in development)Engineering Considerations
What underwater power requires.
Pressure housing design
Enclosures engineered to maintain structural integrity at depth, balancing wall thickness against weight and buoyancy requirements.
Sealed connectors & potting
Connector systems and potting compounds that prevent water ingress through thousands of mate/unmate cycles in field service.
Thermal management at depth
Heat dissipation strategies that work inside a sealed enclosure, where convective cooling from the surrounding water must be accounted for.
Corrosion-resistant materials
Marine-grade materials and coatings selected for long-term saltwater exposure across the pack, housing, and connectors.
