Rechargeable Li-ion batteries modularly divided into SmartPowerBlocks™ (SPBs bring highest capacity and combine safety, reliability and low weight. These batteries are available in three different standard diameters: 260mm, 310mm, 416mm (dimensions without pressure housing). They are partly type-qualified according to MIL-STD, API17F or international standards. The batteries can be qualified to UN T38.3 upon request.

Typical applications for our Vehicle Batteries:

• Underwater vehicles: AUV, ROV, submarines
• Surface vehicles: USV, boats
• Underwater equipment: monitoring stations
• Smart sensor power supplies

We offer COTS (Commercial Off The Shelf) and customised battery solutions. Increased safety is achieved by dividing the battery into self-protected SmartPowerBlocks™ (SPB) modules with their own BMS protection. We only use industrial 18650 cells with the highest energy density, which themselves have extensive protection such as overpressure valves, overcurrent and temperature protection, housed in stainless steel shells. In contrast to pouch cells / Li-Pol cells e.g. used for pressure-neutral batteries, these batteries can be certified and undergo shock and vibration tests, e.g. in accordance with MIL-STD or API17F.

As a manufacturer of corrosion-free and lightweight titanium 1 atm pressure housings (not oil-filled), the batteries are easily scalable with low weight under water. The battery is easy to install (self-supporting) and has a low cable count. This saves buoyancy and thus considerable costs, simplifies the system design and offers extremely high safety even under rough sea and shipboard conditions.
