Battery Pack

The second generation battery pack, with features that make the pack easy to handle and service. The lightweight glass fibre composite case eliminates cathodic issues found with metal cans. The endcap connector guard doubles as a lever making the release of the endcap a low-effort and safe procedure. The lever handles help users transport the battery pack easily. The pack can be configured for different chemistries, including alkaline, and lithium primary. The pack uses standard D-cell units that can be sourced directly by the user if required. This also means that lithium battery packs can be shipped empty, and the D-cells drop-shipped directly from the battery manufacturer, greatly simplifying the use of large lithium packs. The battery pack is available in two depths 200m rated (as shown in pictures below) and 3500m rated. The 3500m rated has a titanium endcap and bottom.


Future options for the pack include massive data memory(4TB) for combining multiple hydrophones, and a data-processing Hub that runs Ocean Sonics’ classifiers, or can run Linux-based custom classifiers.

"We have been working with Ocean Sonics in our technology demonstration program since the first prototypes. Our science users have been very impressed with the very high quality data sets. Ocean Networks Canada is expanding our hydrophone network with Ocean Sonic icListen HF smart hydrophones across our observatory including new sites across coastal BC, as part of the Smart Oceans™ program. The compact size, Ethernet interface, high reliability and exceptional performance make these systems ideal for ocean observing applications such as mammal classification, vessel and ambient noise studies.
