2S 74V Solar Lamp Circuit Board Continuous Current 20A Vacuum Cleaner Power Tools Solar Street Light Protection Board

2 Without equalization and with equalization equalization is to discharge the high-voltage battery cells with resistance when charging and wait for the low-voltage battery cells to charge up the voltage so as to achieve the consistency of each voltage and voltage and the performance of the whole battery pack
3 installing the protection board the batteries must be matched the voltage difference of each battery is not higher than 005V the internal resistance difference is not more than 5mohm and the capacity difference is lower than 30mAh The better the consistency of the battery the farther the running distance will be The working performance of the protection board reaches the best
4 Connect the batteries in parallel first and then in series and make that the welding is 18650 batteries are spot-welded with sheets and other batteries are welded with solder Do not use screws to screw the IC on the protection board
5 note or to leave a message to explain whether you are using a polymer ternary lithium lithium cobalt oxide lithium manganese oxide battery 37V or a lithium iron phosphate battery 32V so as to that the protection board we send is suitable for your battery
