Product overview
The KNS KNS-350-40AH6S semi-solid Li-ion drone battery supplies professional UAV power for surveying, mapping, agriculture, infrastructure inspection, logistics and search-and-rescue operations. Its 6S configuration combines 22.2V with 40000mAh capacity, 888Wh energy and 350Wh/kg energy density. Continuous discharge is rated at 3C, with a maximum discharge rate of 5C and a charging rate of 0.5-1C. The battery weighs 2750g, carries an XT90S plug and has a cycle life of 500 cycles. Charging operates within 0℃～45℃; discharging operates within -20℃～55℃.
The battery uses a semi-solid electrolyte to minimize leakage and thermal runaway risks. Cells are matched by voltage, internal resistance and capacity, then integrated with a PCB incorporating overcharge, overdischarge, MOS and temperature protection. Aluminum sheet and tape provide additional pack protection, while black and clear PVC film forms the protective wrap. Each battery undergoes voltage and internal resistance checks followed by aging testing. For shipment, the pack is protected by bubble column packaging inside a carton box with foam protection.
