Overview
RBR offers optional battery canisters which can extend deployment of any underwater instrument, including these options:
-
quick-release or low-profile handles
-
750m or 4000m, and 8000m depth rating
Fig. 1 shows an RBRfermata suitable for deep deployment with quick-release handles. Fig. 2 shows a shallow variant with low-profile handles, which allow for flexible integration where space is restricted e.g., with the Wirewalker (DMO).

The RBRfermata automatically configures the internal arrangement of batteries, regardless of cell voltage or chemistry, to provide the nominal output. It extends deployments by supplying up to 2.8kWh of energy to any underwater instrument. This is about forty times greater than our standard battery carriage capacity. The instrument incorporates the in-the-housing detection, overcurrent protection with retries, 8V low voltage shutoff with retries, soft start, and 5A current limit per MCBH port. The end-cap features three mounted MCBH connectors and the battery pack design accommodates 48 individual D-cells. An innovative battery carrousel facilitates simple, tool-free battery replacement with status indicator LEDs communicating correct battery loading, as shown in Fig. 3.
