Product overview
Guizhou Super Energy Era Technology Co., Ltd.’s Skyward 21700/4.0 is a cylindrical battery cell for integration into powered equipment, including UAV power systems. Its physical architecture combines NCM-Si/Gr chemistry with a hybrid solid–liquid electrolyte in the 21700 format. The configuration is a cell, rather than a flight platform or airframe kit. With a maximum height of 68 mm, it provides a defined dimensional constraint for equipment integration; its electrical specifications are 4.0 Ah rated capacity, 3.70 V nominal voltage and 14.8 Wh rated energy.
Electrical integration must accommodate the 2.50–4.20 V operating range, a maximum charge rate of 3C and a maximum continuous discharge rate of 15C. Charging is specified for 0–45 °C, while discharging covers −20–60 °C. Cycle life depends on the stated test condition: 1C/1C gives 500 cycles × 80%, and 2C/1C gives 400 cycles × 70%. Cell selection therefore needs to follow the discharge rate of the intended application. The applicable standard is GB 31241-2022.
