Fast-Charge Batteries

As we live in an era of high efficiency, the charging speed of Lithium-ion Polymer batteries has become a major concern. Since our founding in 1998, we’ve always prioritized the development of energy technology, which is why we offer fast-charging batteries that can be charged at 3C or even 5C. Our products will greatly shorten your charge time and, thus, improve the charging efficiency.

Why Do We Need a Fast-Charge Battery?

Long endurance is ideal, but the problem is that the big battery usually requires a longer time to be fully charged. However, it is impractical to wait for them to be fully charged especially when the time is tight. Since fast charging can provide the battery as much power as possible in a short time, this technology allows the higher-capacity batteries to be fully charged in less time.


Fast charging technology ultimately saves time and improves the efficiency of the product. As the technology has matured, more and more products have begun to apply it, such as mobile phones, drones, electrical tools, emergency power supplies, wearable devices, etc. Consumers thus readily enjoy the benefits of fast charging.
