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.

What is a Fast Charge Battery?

A fast-charge battery is a battery that can be charged to 80% or 100% in a short period of time. The technology changes the electrolyte formation to allow the battery to withstand a higher current and quick, full charge.
The diagram above illustrates how a Lithium-ion Polymer (LiPo) battery is charged in a constant current charging process for fast charging. When the voltage reaches the upper limits, it is adjusted to constant voltage charging to make the battery charge saturated.
Throughout the process, different standard charging currents are available for different batteries. For example, 0.1-0.5C is generally selected for 3C batteries while 1C is generally selected for high-power batteries. Choosing a lower charging current also takes the safety of the battery into consideration. The usual fast charge charging current is several times higher than the standard charging current.

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.

Why Should We Choose Grepow's Fast-Charging Batteries?

Grepow battery has adopted the stacking technology while applying Grepow's unique high power electrode formulation and manufacturing process, the batteries of fast charging and discharging at different rates can be designed. Grepow is the largest manufacturer for the Chinese high magnifying power lithium polymer battery, the fast charging is based on the high power cell, and it is also one of the Grepow's core technology. It has the following advantages:

01

Faster Charging

Grepow batteries can be charged up to 3C or 5C, much faster than the standard battery. This greatly saves on charging time and increase the battery’s efficiency.
02

Stable Temperature

During the fast charging process, the temperature increase is stable: The surface temperature of the battery will not exceed 65℃.
03

Long and Durable

After fast charging for more than 500 times, the battery still carries up to 80% of its capacity;
04

Safe and Reliable

Grepow batteries are certified with many Lithium battery safety standards, such as IEC, UL, PSE, and UN38.3 to just name a few.
