Product Overview
Description
Shenzhen Yukun Technology Co., Ltd. is a manufacturer integrating R&D, production and sales of supercapacitor batteries integrating supercapacitor power density and battery energy density.
Product Description
Advantages of super capacitor battery
1) No less than 20,000 cycle life. Use it for ten years, it still works.
2) Great safety and reliability: Unlikely to catch fire or explode. Much safer than chemistry-based batteries.
3) Energy density is 75-220wh/kg. Lots of power in small unit.
4) Quick charge: 80% charge in 5-15 minutes.
5) -40℃ to 70℃ range of operating temperature. Suitable for harsh condition.
6) Cost-efficient: Not necessary to replace for years. One-time investment
