The article focuses on the capabilities of batteries to maintain the performance and endurance of electric drone aircraft. It notes that the batteries used in advanced applications employ secondary cells while primary cells offer some performance advantage. The LiPo cells used in the Zephyr Hale aircraft of Qinetiq lasted more than two hours. According to Boeing Integrated Defense Systems and Lynntech, fuel cell propulsion is not suitable for large drones.
