The battery circuit board, mainly in the lithium battery, plays a protective role in the lithium battery.
The internal resistance of lithium batteries is low and the current they provide is large. In addition, over-discharge of lithium batteries seriously affects the battery life with this protection board, when the discharge voltage is lower. than a certain value. It will turn off to protect the battery.
Yes. The lithium radio battery has a circuit board. The names of circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, printed circuit board, PCB board, aluminum substrate, high frequency board, thick copper plate, impedance . board, PCB, ultra-thin printed circuit boards, ultra-thin printed circuit boards, printed circuit boards (etching technologycopper), etc. Printed circuit boards make circuits miniaturized and intuitive and play an important role in the mass production of fixed circuits and optimization of the layout of electrical appliances.
