Qccan 3S 40A 12.6V Li Ion Lithium Battery Protection Board Pcb Bms Charger Protection Circuit For Drill Motor (3S 40A)

Product Name: 3 String 12.6V 40A Lithium Battery Protection Board&Nbsp;Charging Voltage: Dc 12.6V~13.6Vcontinuous Discharge Current: 40A Maximum (If The Heat Dissipation Environment Is Not Good, Please Reduce The Load Current)Continuous Charging Current: Up To 20Aapplicable 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&Nbsp;Note 1: Successfully Start The Drill Requires 3 10C-20C Power Batteries, Or 6 5C-10C Power Batteries (Recommended Power Battery Models: Compatible&Nbsp;For 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.&Nbsp;Hardware Preparation:Prepare 3S 12.6V 40A Lithium Battery Protection Module, Battery, Power Supply, High Power Load Resistor.The Figure 5 Shows The Module Diagram. The Battery Is 3 Strings. The Connected Battery Needs To Meet The 40A Discharge Current. It Can Be Realized By Paralleling The Battery Or Purchasing A Battery With A Large Discharge Current. For Example, If The Battery Is 2000Mah And The Discharge Multiple Is 10C, Then Only 3 Strings Of 2 Are Needed And The Discharge Current Is 40A.The Charging Voltage Is Dc12.6V~13.6V. The Charging Current Depends On The Battery Connected, And The Maximum Is No More Than 20A. The Module Has A Balanced Charging Path, And The Equalization Function Works Only When The Battery Performance Is Not Much Different.Package Included:4Pcs 3 String 12.6V 40A Lithium Battery Protection Board
