The Customized Underwater Sealed Cabin for ROV/AUV, Battery Cabin, 50-5000m Seawater Depth is a pressure-tolerant battery cabin: the battery pack lives inside a sealed marine-grade alloy (per drawing) housing rated to 50-5000m seawater depth, with the power and signal leads leaving through wet-mate penetrations. The end cap carries an O-ring seal and a restrained bolt pattern, so the pack can be serviced between missions without re-machining anything.

Structure & Pressure Design
The tube is machined or rolled-and-welded with full-penetration seams, then stress-relieved and pressure-checked before finishing. The end cap seats on a grooved O-ring and is held by a bolt circle sized so the seal stays compressed at depth; penetrations are installed in machined ports rather than drilled-through, keeping the wall continuous around every opening.
Applications
- ROV/AUV battery compartments
- Subsea energy storage for long-endurance platforms
- Pressure-tolerant power modules for offshore equipment
Customization & OEM
- Diameter, length and end-cap style per your drawing.
- Depth class and material (316L / titanium / alloy) sized to the working depth.
- Port layout: wet-mate connectors, potted glands and blind bosses as required.
- Internal rails, standoffs and battery restraints for your payload.

FAQ
What is the MOQ?
MOQ is 1 piece for trial orders; volume pricing is available on request.
Can it fit my battery pack?
Yes — send the pack dimensions, weight and connector list; the internal layout and penetrations are built around it.
How is the depth rating verified?
Each vessel is pressure-tested before shipment; test depth and duration are reported with the unit.
Can penetrations be added later?
Ports can be machined in at order time; adding them after delivery is possible but requires re-proof testing.
Is there a warranty?
One year warranty with technical support; spare parts available on request.
How do you ship?
Foam-packed export case; express, air or sea freight per size.
