The traditional lithium-ion battery with protective plate is connected with a protective circuit at the negative electrode through a nickel sheet. The UB14-18 uses a built-in protection circuit in the battery anode technology, and the steel shell is riveted and integrated with the battery, which effectively avoids short circuit caused by collision or wear, and does not increase the battery diameter.

Type-C USB charging interface is set in the positive protection circuit. It can be connected to a USB charging cable to connect a 5V adapter to directly charge the battery, or it can be connected to the USB interface of a computer with high current output. It can also be connected to a mobile power supply to charge the battery. You can also put the battery into the charger when charging. There is a charging indicator on the battery to indicate the charging status. The red light is charging, and the blue light is full.
