• Lithium-ion 28v 54Ah battery for a leading UK defence prime
• Projects developed under DEF STAN 00-56 and IEC61508, achieving better than SIL1 for hardware and software interfaces
• Products designed under DAOS authority, achieving clearance to fly in controlled UK airspace

Bespoke power solutions for defence & aerospace

We can develop a bespoke battery solution to your exact requirements, working as an extension of your team and handling any or all aspects of the project lifecycle from requirements capture through to volume production. We are experienced in working with a range of chemistries and technologies, including rechargeable lithium-ion and lithium polymer.

We also specialise in the development of advanced custom battery management systems that incorporate safety-critical features such as segmented architectures, and can create comprehensive communications protocols that enable easy integration into your vehicle platforms or dismounted soldier equipment.

Manufacturing and test are carried out at our UK-based 600-square meter facilities, where we can handle high or low production volumes. All batteries undergo rigorous testing using state-of-the-art equipment, with key tests including shock, vibration, thermal, electrical, altitude, cell penetration, over-temperature and short-circuit.

COTS Products

We have developed a range of proven off-the-shelf battery products that have been engineered to ensure the utmost in reliability under extreme real-world conditions.
