QUICK START GUIDE

The RBR

fermata 

battery canister extends deployments of all instruments by 

providing up to 2.8kWh of energy to any underwater instrument, which is 
about forty times greater than our standard battery carriage capacity. Housing 
48 individual D-cells and hosting three MCBH connectors, it has both a 12V 
and 24V option. An innovative battery carrousel coupled with quick-release or 
low-profile handles facilitates simple, tool-free battery replacement.
