When fully charged, it can ensure that the voltage difference between individual batteries is less than the set value (generally ± 20mv), achieving equal charging of each individual battery in the battery pack, effectively improving the charging effect under the series charging method. Simultaneously detect the overvoltage, undervoltage, overcurrent, short circuit, and over temperature status of each individual battery in the battery pack to protect and extend the battery&#x27;s service life. Undervoltage protection prevents damage to each single battery due to over discharge during use. The product can work stably and reliably for a long time in the ambient temperature range of -20 ℃ to+60 ℃.</p><p><span style="font-size:20px"><strong>Attention:</strong></span><br/>The lithium battery protection plate cannot be used for Lithium iron phosphate battery, hernia lamp, electric fish machine battery pack, electric bicycle battery pack, children&#x27;s car battery, motor or products with motor, 1W fish eye LED lamp, please pay attention to customers who buy the above combination!<br/>The described power range is applicable to the following products: massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring backup power supply, and other products.</p><p><span style="font-size:20px"><strong>Package include:</strong></span><br/>1 x Lithium Battery Protection Board<br/><br/></p></div></div><p><br/></p>
