ELSİS provides fully custom-designed battery packs engineered to meet the unique power requirements of mission-critical systems used across defense and aerospace platforms. Our battery solutions are developed entirely in-house, including the design and production of the Battery Management System (BMS), electronic control boards, and mechanical enclosures, allowing us to deliver fully integrated and platform-specific battery systems. With extensive field experience, we have delivered rugged, high-performance battery packs for a variety of demanding applications, including electro-optic targeting systems, communication equipment, and other mobile or vehicle-mounted systems operating in harsh environments. These smart batteries are designed to ensure long cycle life, operational safety, and reliable power delivery, even under extreme temperature, vibration, and shock conditions. Offered as build-to-spec or engineered-to-order solutions, ELSİS custom battery packs are ideal for customers seeking compact, intelligent, and reliable energy sources for modern defense platforms. Whether for new designs or retrofits, we offer end-to-end support from concept to qualification.

The single-hull one-compartment HDW Class 214 Submarine fuses the design principles of the HDW Class 209 family and the outstanding features of the HDW Class 212A boats to create a matchless, cost-effective solution for future oriented navies.

The proven HDW Fuel Cell air-independent propulsion system significantly increases underwater endurance and reduces risks of detection. Increased diving depths, the modular weapon and sensor mix in combination with the fully integrated AIP features make the HDW Class 214 predestined for all modern submarine operations and missions. Furthermore, the large payload permits a wide, flexible scope of missions, ranging from littoral water operations to oceangoing patrols.

Low revolution, permanently excited PERMASYN® motor for maximum speeds without transient 
switching or gear noises.
High shock standards.
Optimized own signature management.
Optimized sonar capabilities for increased low-frequency detection ranges (expanded flank array sonar).
Large weapon payloads for a mix of torpedoes, missiles and mines.
Integration of Torpedo Countermeasures (TCM) system.
Universal deployment capabilities.

Deck cargo barges have a distinctive shape, with a flat top and a flat bottom. They provide a stable surface for large and heavy cargo, often with tie-down points to secure the load. They are usually towed or pushed by tugboats or other vessels as they do not have their own propulsion system. They can be used in a variety of sectors and are an integral part of the maritime transport industry, especially for moving bulk or special goods by water that would otherwise be difficult or impossible to transport by land.

Inquisithor™ is an advanced industrial quadcopter drone designed for a wide range of applications, combining high payload capacity with a compact design. The drone features a transport compartment located at its centre of gravity. Several transport cartridges have been designed for this compartment, and they are available in various configurations depending on the type of material being transported. These cartridges also allow for the release of the transported material directly at the operator's command. With a payload capacity of up to 25 kg and a flight endurance of up to 45 minutes, the drone is an ideal solution for transporting materials, medical and rescue supplies, collecting data using multispectral and thermal cameras or analysing hazardous substances, drugs, explosives,, or radioactivity, using specialised detection devices. Folding arms ensure easy portability and space-saving storage. Inquisithor™ utilises a proprietary open control system that enables easy upgrades and customisation to meet specific user needs. Its advanced features include Ghost Mode, which allows autonomous target searching without data transmission, Loitering Mode for operations independent of GPS, and tactical equipment, including a release mechanism. Inquisithor™ is fully compatible with the MPU-5 system and made exclusively from European components, ensuring top-tier quality, reliability, and durability. A unique, sophisticated ground control station, specifically developed by ProLab Engineering for this device, can also operate the Inquisithor.
