Powering Unmanned Aerial Vehicles (UAVs)

As with large industrial UAVs, those deployed within the defence and security sector require equally powerful, yet compact and lightweight battery packs, to power a multitude of critical and highly complex systems. With many years of experience in this sector, we have exceptional expertise in designing, testing and building the advanced power systems required. Find out more about our battery pack capabilities for large AUVs.


Portable power and energy storage

Our portable power products offer huge benefits compared to more traditional electrical generators. Your applications can be powered almost silently and without the need to carry additional fuel for the duration of the charge, thereby saving weight and space.

The lack of moving parts affords much greater reliability in harsh environmental conditions and clean running means that power can be supplied in enclosed spaces safely.

Deployed around the world in some of the most challenging environments, we have designed our battery packs for military applications and operations where immediate, highly reliable power supply is a necessity.
