Product FAQs

A cylindrical UAV battery uses 21700 or 18650 lithium‑ion cells arranged in a structured pack to deliver stable high‑current output, strong mechanical durability, and long cycle life. It is widely used in industrial‑grade drones requiring reliable and continuous power.

  • Higher structural strength — metal casing provides excellent impact and vibration resistance
  • Stable high‑current discharge — ideal for high‑load UAV missions
  • Long cycle life — typically 800–1500+ cycles
  • Better thermal management — uniform cylindrical geometry improves heat dissipation
  • Consistent performance — lower internal resistance and stable voltage output

Cylindrical batteries are ideal for:

  • Industrial inspection drones
  • Security and surveillance UAVs
  • Agricultural spraying drones
  • Logistics and delivery drones
  • Mapping and surveying UAVs
  • High‑power FPV platforms

PKNERGY provides cylindrical UAV battery packs in multiple configurations:

  • Voltage platforms: 3S / 4S / 6S / 12S
