<br/><b>Specification:</b><br/>Item Type: Lithium Battery Balance Module<br>Material: PCB<br>Charging Voltage: 16.8V-18.1V<br>Continuous Discharge Currentupper limit: 40A if heat dissipation environment is not , please reduce load current<br>Continuous Charging Currentupper limit: 20A<br>Standard Version: Suitable for starting current below 60A, power below 100W drill<br>Enhanced Version: Suitable for starting current below 80A, power below 135W drill<br>Balanced Version: Suitable for starting current below 80A, power below 135W drill <br/><br/><b>Package List:</b><br/>4 x Lithium Battery Balance Module <br/><br/><b>Note:</b><br/><div>1. Successfully starting the drill requires 4pcs 15C-20C power batteries, or 8 10C-15C power batteries ordinary  can't start the drill!.</div><div>2. Wire 0V, 4.2V, 8.4V, 12.6V, 16.8V strictly according to the drawing, do not intentionally short circuit.</div><div>3. with the load of brush motor, as far as possible in the motor positive and negative terminals in parallel with a non  capacitorvoltage resistance of more than 25V, capacity of 10uF-100uF, to prevent the motor generated by the reverse  voltage interference  plate or breakdown of MOS tube.</div><div>4. If four groups of batteries are connected in series,  that the voltage of each group is the same. If the voltage is different,  each group of batteries separately and use them in series. In the discharge , the battery with the faster voltage drop is the differential battery. For some customers with poor electronic basis explain: balanced charging is only an auxiliary function, try not to use the  battery and the bad battery together! The closer the capacity or internal resistance of the four batteries is, the better! 3  batteries and 1 bad batteries = 4 bad batteries.</div>
