Underwater External Power System for Sony Cameras (NP-F970)
Extend your underwater camera runtime up to 3–5x using a sealed external battery system based on Sony NP-F970.
This underwater external power system provides stable and extended power for cameras, monitors, and video systems. It eliminates the limitations of internal batteries and allows long-duration underwater operation without opening the housing.
The Problem
Internal camera batteries quickly deplete underwater, requiring frequent resurfacing and opening of the housing. This interrupts operation and increases risk of water ingress.
The Solution
This external power system supplies continuous power from a sealed waterproof battery housing using high-capacity Sony NP-F970 batteries.
Typical System Setup
External battery system → power cable → waterproof bulkhead connector → underwater housing → camera or monitor
