Product overview

The KNS KNS-400-31AH6S supplies UAV power through a 6S semi-solid state battery with 31000mAh capacity and a nominal voltage of 21V. Designed for heavy-lift drones and long-endurance industrial missions, it supports applications including aerial window cleaning, construction inspection, cargo delivery, mapping and surveying. Its application range also covers power line, pipeline, wind turbine and bridge inspection, emergency response, search and rescue, and VTOL or eVTOL platforms. The semi-solid state electrolyte helps reduce thermal runaway risk.

The battery provides 651Wh of energy, with an energy density of 400Wh/kg, a weight of 1860g and an XT90S plug. Continuous discharge is rated at 3C, maximum discharge at 5C, and charging at 0.5-1C. Charging operates within 0℃~45℃, while discharging operates within -10℃~55℃; cycle life is 500 cycles. Each battery is individually packed with shock-absorbing foam and anti-static materials, with terminal insulation and hazard labels included. The battery complies with UN38.3 for air and sea transport.
