AEROPAK G is an ultra lightweight fuel cell system that increases UAV flight duration by a factor of 2 to 5 over traditional lithium-ion batteries.

These high energy-density hydrogen batteries are able to store 700Wh/kg compared to 190WH/kg offered by traditional storage means. AEROPAK G can be used to power small-to-medium sized commercial UAVs carrying high precision sensors and used to perform missions in which endurance is key. Cylinders can be refilled on the ground through an optional mobile refuelling station.
