Description:
3 S 12.6V lithium battery protection board
Application: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, lithium polymer battery)
Product Size: 50 * 16.5 * 3mm
Charging voltage: 12.6V-13.6V
Continuous discharge current (upper limit): 10A (If the cooling environment is not good, please reduce the load current use)
Note 1: Strictly according to the diagram wiring 0V, 4.2V, 8.4V, 12.6V (0V or 12.6V then wrong board, 4.2V or 8.4V wrong not working).
Caution 2: When a load with a brush motor is used, a non-polar capacitor (with a withstand voltage of 25V and a capacity of 10uF-100uF) must be connected in parallel with the positive and negative terminals of the motor to prevent the reverse spike voltage generated by the motor from interfering with the protective plate or Break through the MOS tube.
Caution 3: When connecting 3 batteries in series, please ensure that the voltage of each battery is the same. If not the same, please fill each battery separately and use it in series. . . The discharge test, the voltage drop faster that group of batteries is bad battery.
Note:Do not deliberately short circuit !
