Are you factory?

We have factories both in Dongguan China. The factory covers an area of 12000㎡ Has 500 employees And 25 R&D engineers.We can produce 100000 lithium batteries every dayThe factory has passed SGS & TUV QMS certification.

Are there any industry certifications or standards met by your li-ion 21700 batteries?

Our li-ion 21700 batteries comply with industry standards and may have certifications such as UL, CE, or RoHS, depending on the application.

How long do lithium batteries last?

Our lithium battery cycle life is more than 500 times. The lifespan of a lithium battery depends on various factors, such as usage patterns, charging and discharging conditions, and overall maintenance.

How long does it take to fully charge a lithium battery?

Charging time depends on the battery's capacity and the charger's current. For example, if the battery capacity is 4000mAh and the charger current is 2500mA, charging time = 4000mAh / 2500mA = 1.6 hours.
