Surface Button Introduction

Precision movement safety protection

 Powerful battery management system,Significantly improve battery cycle life.

voltage balancing circuit: Due to subtle industrial errors, there are capacity differences among lithium batteries of the same model. However, most power banks have overcharge and discharge protection, but there is no voltage balancing circuit set up. There is no difference in short-term use. Over time, this difference will gradually be amplified, and batteries with smaller capacities will enter protection in advance. Some batteries cannot be fully charged and discharged, resulting in a sharp decrease in overall capacity. The voltage balancing circuit aims to balance this difference, significantly improve the cycle life of battery cells, and eliminate safety hazards such as bulging and leakage.

FAQ：

Q:What information do customers need to provide after purchasing this product?

A:The customer needs to provide the DC input voltage and current of the electrical equipment, as well as the specifications of the
DC interface.If your electrical device is a laptop, you can take photos of the parameters on the label paper at the bottom of the
laptop and the label parameters on the surface of the power adapter (requiring clear visibility of voltage, current, brand and
model), as well as a picture of the circular metal plug of the power adapter. If conditions permit, you can measure the
diameter.of the circular metal plug of the power adapter.
