330wh/kg 27000mah 21.9v 6s Solid State Lithium Ion Battery Pack

Product Advantage

Ultra-lightweight, extended endurance

With 330Wh/kg energy density, this pack is 30% lighter than conventional LiPo – giving you longer flight times or higher payload capacity.

Solid-state safety, zero thermal runaway

Solid electrolyte eliminates leakage, swelling, and fire/explosion risks – even under puncture or overcharge conditions.

Wide-temperature reliability

Operates from -20°C to 55°C, delivering consistent discharge performance in freezing high-altitude or scorching field environments.

Steady power & long cycle life

Supports 3C continuous discharge with a flat voltage curve; retains >80% capacity after 500 cycles – combining high output with lasting durability.

Parameter Property

What is this product?

This 6S solid-state battery packs 27,000mAh at 21.9V with a 330Wh/kg energy density – 30% lighter than conventional LiPo. That extra weight savings translates into longer flight times or heavier payloads for your UAV, eVTOL, or robotic platform. It delivers steady 3C continuous discharge across -20°C to 55°C, while the solid electrolyte ensures zero leakage and no thermal runaway. Cycle life exceeds 500 cycles with >80% retention, and UN38.3/MSDS certification makes global shipping hassle-free. Simply put: it’s the reliable, high-efficiency power source for demanding missions.

Application

Long-endurance UAVs

Power line inspection, pipeline monitoring, aerial mapping, and agricultural spraying. 330Wh/kg delivers 40+ minutes of flight time, while lighter weight allows more payload for sensors or liquids.

eVTOL Aircraft

Urban air mobility, passenger drones, cargo carriers. 

Industrial & Specialized Robotics

Inspection robots, rescue robots, underwater/ground platforms. 

Heavy-lift Logistics & Cargo

Large freight drones, emergency supply delivery. 30% weight reduction over LiPo translates into extra kilograms of payload per flight, boosting operational efficiency.

Application Case

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.
