The lithium battery protection board adopts a highly integrated intelligent lithium battery protection board integrated chip, and the performance is superior to the protection board composed of discrete chips. Can complete 3/4/5 string polymer lithium battery, ternary lithium battery, lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide battery charge and discharge protection, over current, short circuit, over temperature protection and equalization function. It adopts 4 milliohm ultra-low internal resistance MOS tube, which has low internal resistance and high efficiency. It is suitable for battery pack applications in different fields such as inverters, DC motors, power tools, and solar street lights. It is common to the same port and diffierent port, and has strong applicability. The protection board has a heat sink and connecting wire.
