Lithium Battery Equalizer 4Pcs PCB Lithium Battery Protection Plate 40A Portable Accurate Detection For Electric Drill

Lithium Battery Equalizer 4Pcs PCB Lithium Battery Protection Plate 40A Portable Accurate Detection for Electric Drill Specification: Item Type: Lithium Battery Balance Board Material: PCB Charging Voltage: 16.8V-18.1V Continuous Discharge Current upper limit: 40A if the cooling environment is bad please reduce the load current for use Continuous Charging Current upper limit: 20A Standard Version: Applicable to electric drills with starting current below 60A and power below 100W. Enhanced Version: Applicable to electric drills with starting current below 80A and power below 135W. Equalizing Version: Applicable to electric drills with starting current below 80A and power below 135W Package List: 4 x Lithium Battery Balance Board Note: 1: Four 15C to 20C power batteries or eight 10C to 15C power batteries are required to successfully start the electric drill ordinary cannot start the electric drill!!!. 2: Wiring 0V 4.2V 8.4V 12.6V 16.8V in strict accordance with the diagram and do not intentionally short circuit. 3: When the load with brush motor is used try to connect a non capacitor withstand voltage of more than 25V capacity of 10uF to 100uF in parallel at the positive and negative terminals of the motor to prevent the reverse voltage generated by the motor from interfering with the protection board or breaking through MOS tubes. 4: When four groups of batteries are connected in series please ensure that the voltage of each group of batteries is the same. If not please fully charge each group of batteries separately and then use them in series. During the discharge test the group of batteries with fast voltage drop is the poor battery. Explain to some customers with poor electronic that balanced charging is only an auxiliary function. Try not to mix batteries with poor batteries! The capacity and internal resistance of the four batteries are as close as possible! The use effect of three batteries and one poor battery is equal to that of four poor batteries..
