4S 14.8V 16.8V 18650 Lithium Battery Protection Board Startable Electric Drill 40A Current

Specifications Scope of application Lithium batteries with nominal voltages of 3 6V and 3 7VProduct size 46 60 3 4mmProduct weight 10 3gCharging voltage 16 8V 18 1VContinuous discharge current upper limit 40A If the heat dissipation environment is not good please reduce the load current to use Continuous charging current upper limit 20AApplicable electric drill electric drill with starting current below 80A and power below 135W Note 1 To start the electric drill successfully you need 4 power batteries of 15C 20C or 8 power batteries of 10C 15C ordinary 18650 cannot start the electric drill 2 Wire 0V 4 2V 8 4V 12 6V 16 8V strictly according to the diagram and do not intentionally short circuit 3 For loads with brushed motors try to connect a non polar capacitor in parallel with the positive and negative terminals of the motor withstand voltage above 25V capacity 10uF 100uF to prevent the reverse peak voltage generated by the motor from interfering with the protection board or breakdown MOS tube 4 When connecting 4 sets of batteries in series please ensure that the voltage of each set of batteries is the same If they are not the same please charge each set of batteries separately and use them in series During the discharge test the battery with the faster voltage drop is a bad battery Package Included 1 x 4S 14 8V 16 8V 18650 Lithium Battery Protection Board
