Product features:

1. High energy density

The weight of lithium polymer batteries is half that of nickel cadmium or nickel hydrogen batteries of the same capacity, and the volume is 40-50% that of nickel cadmium and 20-30% that of nickel hydrogen.

2. High voltage

The operating voltage of a single lithium polymer battery is 3.7V (average), which is equivalent to three nickel cadmium or nickel hydrogen batteries connected in series.

3. Good safety performance

The outer packaging is aluminum-plastic packaging, which is different from the metal shell of liquid lithium batteries. Due to the use of flexible packaging technology, internal quality hazards can be immediately displayed through deformation of the outer packaging. Once a safety hazard occurs, it will not explode but only swell.

4. Long cycle life

Under normal conditions, the charge and discharge cycle of lithium polymer batteries can exceed 500 times.

5. No pollution

Lithium polymer batteries do not contain harmful metal substances such as cadmium, lead, mercury, etc.

6. No memory effect

The memory effect refers to the phenomenon in which the capacity of nickel cadmium batteries decreases during the charging and discharging cycles. Lithium polymer batteries do not exhibit this effect.

7. Fast charging

Using a constant current and constant voltage charger with a rated voltage of 4.2V can fully charge lithium polymer batteries within one to two hours.

8. Complete range of models

Complete range of models, wide capacity and size range, can be designed according to customer needs, with a single thickness of 0.8-10mm and a capacity of 40mAh~20Ah.

Application areas:

Bluetooth earphones, smart wearables, GPS navigation devices, POS machines, power banks, learning devices, tablets, car navigation, MP3,MP4,MP5, Card insertion speaker, wireless mouse, Xiaomi display screen PSP built-in battery, Apple peripheral power supply, tablet computer, mobile DVD, laptop battery, wireless monitoring device, medical equipment, various instruments and meters, LED lamps, traffic signs, portable small appliances, various DIY instruments and meters, metal detectors, and other digital battery products.
