This is a 350Wh/kg semi-solid drone battery from KNS, with a 6S 22.2V configuration and 35000mAh capacity. It delivers 777Wh of total energy at a lightweight ~2.46kg, offering exceptional endurance for heavy-lift and long-mission UAVs. Already in mass production and field-proven for over a year, it combines ultra-high capacity with real-world reliability – ideal for agricultural, logistics, and inspection drones.
Designed for heavy-lift and ultra-long-endurance UAV missions requiring maximum energy per flight:
Agricultural Spraying – Cover larger fields per sortie, reduce battery swap frequency
Logistics & Cargo Delivery – Extended range for last-mile and beyond-visual-line-of-sight (BVLOS) operations
Long-Range Mapping & Surveying – Continuous flight over vast areas without mid-mission landings
Pipeline & Power Line Inspection – Reliable power for remote, extended-duration tasks
Search & Rescue – Maximized loiter time for critical, time-sensitive missions
Heavy-Lift Industrial Drones – Carry higher payloads while maintaining operational endurance
Autonomous Robotics & Large-Scale EV Platforms – 6S compatible high-capacity power source
Custom configurations available for other demanding applications.
