Refillable Battery Container


Battery Container

The develogic refillable battery containers are designed to fit inside our MCH composite pressure housings that are available for shallow (up to 750m) and deep water (up to 6,000m) as well as into our range of Deep Water Titanium Housing (DW.TH). The battery containers can be mounted onto the DW.TH and MCH standard, compact and large housing caps. Our pressure housings can therefore be transformed into flexible external power supply solutions for your instrument set-up.

The battery containers are made of fibre reinforced synthetic, anodized aluminium. Key features are light weight and easy servicing. Off-the-shelf available lithium, alkaline or NiMH battery cells can be refilled by the customer.

Configurable Battery Container

Our configurable battery containers are a flexible and easy to handle solution to submarine power supply requirements.

They are designed to fit into develogic MCH and DW.TH housings and to accommodate LR20 (size D) primary or rechargeable standard batteries and are available in several sizes up to 171 cells for MCH Housings and 56 cells for DW.TH housings. Custom DW.TH housings can be equipped with larger battery containers.

The container integrated circuit board with its Schottky-diode-matrix supports the safe operation of e.g. the 49-cell container in 7p7s, 3p14s, 2p21s or 49s configurations.

If equipped with Lithium Primary Cells this 49-cell container delivers – depending on the chosen cell type and discharge characteristics – up to 3,000Wh@25V or 2,500Wh@50V.

With Alkaline batteries 880Wh@10.5V or 750Wh@21V & 42V are possible.

If the container is to be equipped with rechargeable cells, a low-voltagecutoff option is available in the integrated circuit board in order to avoid deep discharge.
