Underwater Battery Canisters
RBRfermata & RBRfermette³
This battery canister, rated to 750dbar, is capable of extending deployments for all RBR instruments and any other devices requiring a nominal 12V supply. Four MCBH connectors are mounted on the top end-cap, and the battery pack design includes 56 D-cells, soldered with reverse- and short-circuit protection, in a single wrapped pack.
The RBRfermata prolongs the life of all deployments by providing 1kWh of power to any underwater instrument. For standard RBR instruments, this is approximately a 40x improvement to our extended battery carriage capacity.
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.
Drawings for the battery packs are available to aid local sourcing, particularly in the case of lithium packs (which further increase the autonomy).
