Long-range reconnaissance & surveillance – 90+ minute flight times allow fixed-wing and multi-rotor UAVs to cover vast borders, ocean areas, and pipeline networks in a single sortie, reducing the need for relay stations.
Urban air mobility (eVTOL) – With 1.66kWh and solid-state safety, this pack supports short-haul passenger shuttles and cargo pods, meeting the strictest thermal runaway requirements for city-centre operations.
Disaster response & humanitarian aid – Rapidly deployable power for search-and-rescue drones, portable field hospitals, and communication relays in areas where grid power is cut off.
Autonomous maritime & subsea systems – Powers long-endurance USVs (unmanned surface vessels) and AUVs for seabed mapping, cable inspection, and oceanographic research – operating reliably in salt spray and wide temperature swings.
Remote industrial sites – From mining and construction to offshore wind farms, this battery keeps inspection robots, telepresence units, and heavy-lift drones running without frequent recharges, cutting downtime and logistics costs.
