Description

The RBRfermata battery canister extends deployments of all instruments. It automatically configures the internal arrangement of batteries regardless of cell voltage (lithium at 3.6V, alkaline at 1.5V, Ni-MH at 1.2V) to provide a nominal 12V output. Housing 48 individual D-cells and hosting three MCBH connectors, the RBRfermata has both a 12V and 24V option. The RBRfermata extends deployments by providing up to 2.8kWh of energy to any underwater instrument, which is about forty times greater than our standard battery carriage capacity. An innovative battery carrousel coupled with quick-release handles facilitates simple, tool-free battery replacement. Polyfuses ensure overcurrent protection, resetting automatically after a fault. As an alternative, you can also extend your deployments using the compact RBRfermette³.

Featuring a single MCBH connector, this battery canister accommodates 8 AA cells.
