2. Why INR21700‑60XG suitable for UAV & Drone Application?
Ultra‑low internal resistance ≤5mΩ suppresses voltage sag
It delivers stable voltage output under heavy‑load conditions like take‑off and sharp flight maneuvers. It avoids unexpected ESC undervoltage cutoff and reduces heat generation to improve flight reliability and safety.
High pulse discharge for instant thrust requirement
It supports 160A 3‑second pulse discharge, offering sufficient current headroom for climb‑off and sudden payload surges. It perfectly matches burst‑power demands of VTOL and heavy‑lift industrial drones.
Proven vibration & mechanical‑shock resistance for airborne environment
The cell has passed multi‑axis vibration and mechanical shock tests with no leakage, fire or explosion. It can withstand continuous vibration and attitude‑change impact generated during real‑world drone flight.
Wide operating temperature adapts to diverse field missions
Its discharge temperature ranges from ‑20℃ to 60℃ and retains high capacity at low temperatures. It works reliably for high‑altitude, cold‑winter and hot‑summer inspection or agricultural drone operations.
Balanced power‑energy performance with decent cycle life
Combining large 6000mAh capacity and high‑rate capability, it helps drone pack designers balance thrust and flight endurance. It keeps ≥70% initial capacity after 300 cycles to lower long‑term operational costs.
Why Cylindrical Cells?
Cylindrical lithium-ion cells remain a competitive mainstream format thanks to robust mechanical structure, mature automated manufacturing, outstanding cell consistency and inherent cooling channels after packaging.
Enhanced Structural Safety
Cylindrical lithium-ion cells adopt spiral winding construction. The round shape evenly distributes internal pressure, and rigid metal casing accommodates built-in PTC and CID safety devices to prevent deformation and overheating.
Consistent Performance & Scalable Production
Standard sizes including 18650, 21700 and 4680 etc enable fully automated manufacturing. Superior cell consistency optimises the reliability of battery modules and packs.
Efficient Thermal Management for High-Rate Operation
Natural gaps between cells form cooling channels after assembly, effectively mitigating hot spots under high-rate charging and discharging conditions.
Flexible Modular Integration
Adjustable series-parallel configurations support custom battery pack designs for electric vehicles, e-bikes, power tools and stationary energy storage systems.
Controllable Thermal Propagation Risk
Individual cells carry moderate capacity. Energy released during failure is limited, making thermal runaway easier to contain than large-format prismatic cells.
