Ultra‑low internal resistance ≤4mΩ minimizes voltage drop
It maintains steady output during high‑current flight phases. It prevents accidental ESC trigger and restrains heat build‑up for enhanced drone flight stability.
Strong short‑term pulse discharge for rapid thrust output
140A 3‑second pulse discharge provides enough current margin for take‑off, fast ascent and aggressive maneuvers. It fits medium‑payload VTOL, inspection and agricultural UAV projects.
Qualified vibration and shock performance for airborne use
Strict vibration and mechanical‑shock qualification ensures no safety failure. The cell tolerates persistent vibration and sudden impact forces in actual drone airborne conditions.
Broad discharge temperature for all‑weather outdoor assignments
It works stably from ‑20℃ to 60℃, preserving good capacity performance at low temperatures. Ideal for field work in high‑altitude mountains, cold regions and hot open‑air sites.
Optimized power‑energy balance plus longer cycle lifespan
High‑rate discharge paired with 5000mAh capacity realizes good trade‑off between thrust and flight time. It retains ≥60% initial capacity after 500 cycles, effectively cutting total battery replacement costs for drone operators.
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.
