The KNS solid state lithiumion battery pack delivers 340Wh/kg energy density with 28,000mAh capacity at 22.2V (6S). Using true solid state electrolyte technology, it eliminates leakage and minimizes thermal runaway risks. Designed for professional drones, it provides safe, stable, and longlasting power for demanding aerial missions.


Mapping & Surveying – Longer flight endurance for large-area coverage and reduced field trips.
Infrastructure Inspection – Stable power output ensures reliable data for bridges, pipelines, and power lines.
Logistics & Cargo – High capacity supports long-range delivery and heavy-load transport.
Search & Rescue – Solid state safety allows confident operation in remote, harsh environments.


KNS solid state drone batteries have been successfully deployed worldwide. In Pakistan, the 6.2Ah pack powers agricultural surveillance and small-area mapping. In the United States, KNS batteries support power line inspection, high-rise glass-cleaning drones, and R&D tests with robotic arms—delivering stable output and leak-proof safety.
In India, multi-rotor fleets use the 36Ah 6S pack for extended farmland surveying, while heavy-lift operations rely on the 32Ah 14S for cargo and infrastructure inspection. In Chile, heavy-lift drones carry supplies through mountainous terrain using the 32Ah 14S KNS battery, where solid state reliability eliminates leakage and thermal runaway risks.
From precision inspection to heavy-lift logistics, KNS solid state batteries provide the energy density, safety, and endurance professionals trust globally.


Cell match – Check each cell’s voltage, internal resistance, and capacity, then match them into consistent groups.
Tab trimming – Connect cells in series or parallel to assemble into battery packs.
Assemble battery cells – Integrate with PCB board including overcharge, overdischarge, MOS, and temperature protection.
Solder welding – Use soldering iron to heat solder wire, melt it onto target parts, and let cool for solid connection.
Package – Bubble column packaging + carton box with foam protection, ready to ship.
Weighting & aging – Test voltage and internal resistance, then perform aging test on every battery.
Heat shrink packaging – Wrap black and clear PVC protective film, then add label.
Install aluminum panels – Add aluminum sheet and tape to the battery pack for extra protection.
