3 Strings 12V 18650 Lithium Battery Control Protection Board With Balanced Charging

Scope of Application: Applicable to Lithium Batteries with Nominal Voltage of 3.7V and Full Voltage of 4.2V (Including 18650, 26650, Polymer Lithium Batteries, without the Limitation of External Dimensions)

Product Size: 41*55*3.4mm (Enhanced Version)

Product Weight: 8.8G (Enhanced Version)

Charging Voltage: 12. 6v-13.6v

Continuous Discharge Current (Upper Limit):40A (If the Cooling Environment Is Not Good, Please Reduce the Use of Load Current)

Continuous Charging Current (Upper Limit):20A

Enhanced Version: Applicable to Electric Drills with Starting Current below 80A and Power below 130W.

Note 1: Successfully Start the Electric DrillNeed 3 One 15 C- 20C Power Battery, Or 6 One 10 C- 15C Power Battery (Ordinary 18650 Cannot Start Electric Drill!! !); 0V and 12.6V Connecting Wire, Use More than 3 Mm² Copper Wire (Nickel Sheet Cannot Be Used!! !).

Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V in Strict Accordance with the Figure, Do Not Deliberately Short Circuit.

Note 3: When Charging the Battery, It Is Normal for the "430" Resistor to Heat up, Indicating That the Equalization Circuit Is Working; If the "430" Resistor Also Heats up When Not Charging, check Whether the Connection Is Wrong.

For Some Customers with Poor Electronic Foundation, Please Explain: Do Not Mix Good Batteries with Poor Batteries! The Closer the Capacity/Internal Resistance of the 3 Groups of Batteries Is, the Better! (2 One Good Battery 1 One Poor Battery Use Effect = 3 One Poor Battery Use Effect).
