10PCS Li-ion Lithium Battery 3S 4S 40A 60A BMS Enhance/Balance 18650 Charger Protection Board 8.4V 12.6V 14.8V 16.8V For Drill Introduction: Product Name: 3 string 12.6V 40A lithium battery protection board Charging voltage: DC 12.6V~13.6V Continuous discharge current: 40A maximum (if the heat dissipation environment is not good, please reduce the load current) Continuous charging current: up to 20A Balance Version Product size: 41*61*4mm Enhance Version Product size: 41*55*4mm Applicable choice: applicable to the nominal voltage of 3.7V, fully charged 4.2V lithium battery (including 18650, 26650, polymer lithium battery), can be drilled below 170W Note 1: Successfully start the drill requires 3 10C-20C power batteries, or 6 5C-10C power batteries (recommended power battery models: sony vtc4, vtc4A, vtc5A, vtc6) OV and 12.6V cable, use Copper wire of 3 square millimeters or more (nickel sheets cannot be used) Note 2: Strictly connect 0V, 4.2V, 8.4V, 12.6V according to the diagram. Do not touch any components on the board when soldering the wire. Do not intentionally short circuit. Note 3: When soldering the battery for the first time or when charging is in progress, as long as the single battery exceeds 4.2V, the "430" resistor will heat up and discharge (discharge to about 4.19V to stop heating). If the "430" resistor is severely hot, check if the wrong line is connected. Introduction: Product Name: 4 string 14.8V 16.8V 40A lithium battery protection board Charging voltage: DC 16.8V~17V Continuous discharge current: 40A maximum (if the heat dissipation environment is not good, please reduce the load current) Continuous charging current: up to 20A Balance Version Product size: 45*60*4mm Enhance Version Product size: 44*55*4mm Applicable choice: applicable to the nominal voltage of 3.7V, fully charged 4.2V lithium battery (including 18650, 26650, polymer lithium battery), can be drilled below 170W Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!!). Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit. Note 3: When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube. Note 4: 4 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery.
