Charging Voltage: 8.4V - 9.0V Continuous Discharge Current (Maximum): 20A (If the cooling environment is not good, reduce the load current use) Continuous charging current (upper limit): 10A.
Standard Version: Suitable for rigs with currents up to 25A below 50W or resistive loads below 168W. Balanced type: suitable for electric drills below 25A and below 50W, or a start-up current of a resistive load of less than 168W with balanced charge.
Note 1: Two 10C-20C power batteries are required for the successful start of the electric drill, or four 5C-10C power batteries (ordinary 18650 cannot start the drill!). ) ! OV and 8.4V cables, using more than 2 square millimeters of copper wire (no nickel plates!).
Note 2: Connect 0V, 4.2V, and 8.4V in strict accordance with the diagram. When the battery is connected for the first time, it needs to be charged before output.
Note 3: When the battery is charged, the "430" resistance heating is a normal phenomenon, indicating that the equalization circuit is working normally; If the "430" resistor is also heated when it is not charging, check whether the wrong line is connected.
Note: Do not mix good batteries with bad batteries!2 cells of battery capacity/internal resistance should be as close as possible!
