It is powered by the sun during the day, before switching to battery power during the night and can potentially stay airborne for 12 months. Featuring long-life battery technology, ultra-lightweight solar cells, a 35-metre (115 ft) wingspan and a weight of 150 kilograms (330 lb), the aircraft is designed to operate in the stratosphere .

It should cruise at 220 kn (407 km/h, down from 240 kn), have 440 nmi range, 100 nmi (185 km) less than previously, be powered by an 820 kWh lithium-ion battery weighing 3,720 kg (8,200 lb), down from a 920 kWh battery weighing 3,600 kg, would have a 6,350 kg maximum take-off weight, down from 6,668 kg, an altitude ceiling of 32,000 ft and a ...
A Hybrid drone is a type of unmanned aerial vehicle using two or more energy sources to power its flight propulsion system.. UAV systems often use brushless DC electric motors as means of propulsion due to their high efficiency and great controllability, their main energy source is usually a LiPo battery with targets for battery packs for electric vehicles of 235 Wh/kg and 500 Wh/L in 2020.
The ultralight will be powered by high discharge lithium-ion batteries and by eight electric motors which generate 102 horsepower. [6] [5] Battery powered flight time is limited to 20 minutes and there is a top speed of 63 mph (101 km/h). [5] The vehicle comes with a charger which can recharge in one hour at 230/240V or two hours with 110V power.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
The H109 included a set of brushless DC electric motors with a larger transmitter to harness the resulting power. It also has a 20-minute flight time, which is nearly three times longer than most of the previous models. [2] It did not come in a "plus" variety (there is no H109+) which meant that it lacked the altitude hold function.
