Product overview
The Skyward 21700/5.0 from Guizhou Super Energy Era Technology Co., Ltd. is a cylindrical battery cell for integration into equipment power systems, including UAV power applications. Its NCM-Si/Gr chemistry provides a rated capacity of 5.0 Ah and rated energy of 18.0 Wh at a nominal voltage of 3.60 V. The physical architecture follows the 21700 cell format, with a maximum height of 70 mm, supporting cell replacement or upgrades within equipment designs that accommodate this format.
Electrical integration must accommodate an operating voltage of 2.50–4.20 V, a maximum charge rate of 3C and a maximum continuous discharge rate of 15C. Charging is limited to 0–45 °C, while discharging permits −20–60 °C. Cycle-life figures depend on the stated test conditions: 1C/1C yields 500 cycles × 80%, and 2C/1C yields 400 cycles × 70%. Selection therefore depends on the intended discharge rate. The cell lists GB 31241-2022 as its applicable standard and supports thermal abuse testing at 130°C.
