Engineered for professional drone operations requiring extended endurance and uncompromised safety. This solid-state Li-ion battery delivers 310Wh/kg energy density with a substantial 30000mAh capacity in a standard 6S 22.2V configuration. The solid-state electrolyte eliminates leakage and thermal runaway risks, providing reliable power for long-range mapping, surveillance, cargo delivery, and agricultural missions. Drones equipped with this battery can achieve 60–90 minutes of flight time depending on payload, significantly outperforming conventional LiPo batteries at the same weight. Drop-in compatible with most professional UAV power systems.
