Applicable scope: Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without limitation on the dimensions) Product Size: 45*15*3.4mm (Standard), 48*20*3.4mm (Balancing) Charging voltage: 8.4V - 9.0V Continuous discharge current (upper limit): 20A (If the cooling environment is not good, reduce the load current use) Continuous charge current (upper limit): 10A Standard Edition: Suitable for starting drills with currents up to 25A below 50W, or resistive loads below 168W. Balanced version: Suitable for starting currents below 25A and below 50W power drills, or resistive loads below 168W, with balanced charging function. Note 1: The successful start of power drill requires two 10C-20C power batteries, or four 5C-10C power batteries (ordinary 18650 can not start drill! ! !); 0V and 8.4V cable, use 2 square mm Above copper wire (cannot use nickel plate!!!) Note 2: Connect 0V, 4.2V, 8.4V according to the diagram strictly. When connecting the battery for the first time, it needs to be charged before output. Note 3: When the battery is charged, “430” resistance heating is a normal phenomenon, indicating that the equalizing circuit is working; if the “430” resistance is also heating in the state of not charging, please check whether the wrong line is connected. For some customers with poor electronic foundation, please explain: Do not mix good batteries and bad batteries together! The capacity/internal resistance of 2 batteries should be as close as possible! (1 good battery 1 bad battery = 2 battery use effect).

If you are using the speed control (dimming) to do the product, the shop can provide free
Custom service, can be in accordance with the requirements of the customer to modify the shape of the circuit board, installation
Mode, current and voltage parameters, add other functions, etc
Note that the governor is mainly used in motor speed control, if you are used to LED dimming, must ensure that the LED can also work in direct power supply, the dimming range of the speed governor is from LED to LED directly connected to the power supply is completely extinguished between dimming, if LED is directly connected with a power that will burn through dimmer the dimming is burned, which typically requires a series current limiting resistor, if you don't know how much resistance can contact customer service.

Instruction: AC use: Need to apply reactive rectifier for it is DC, constant pressure. During installation, make sure that the medium insulation and tactile surface are tightly coupled and fixed! There shoule no gap! Installed and then power, wait 3 seconds after initialization, it may be normal operation! 2. Recommended method of installation: The first, the shell design a card slot, the touch button can be put in firmly locked. The second, the use of hot melt adhesives, the touch button and shell close to the adhesive hot melt can be used to live. The third, the use of double-sided adhesive, directly touch the stickers inside the shell.

Features:
After power on, the 10 LEDs will light up sequentially from left to right, showing the state of running lights. This kit can display the NE555 timing and CD4017 counting functions intuitively. It is a starter kit for learning timers, counters, frequency dividers, and lantern controllers. At the same time, the kit has good effects, is very interesting and practical, and is also the preferred material for beginners to get started.
Circuit principle:
This kit is mainly composed of a clock generation circuit and a decimal counter circuit. It is a self-excited multivibrator with NE555 as the core. The power supply charges capacitor C2 through R11, R12, and R13. When C2 just starts to charge, pin 2 of NE555 is still in Low level, so the output pin 3 is high. When the power is charged to 2/3 of the power supply voltage to C2 through R11, R12, R13, the level of the output pin 3 changes from high to low, and the internal discharge tube of NE555 turns on , Capacitor C2 is discharged through R13, R12, NE555 pin 7 until the voltage across C2 is lower than 1/3 of the power supply voltage, NE555 pin 3 level changes from low to high again. C2 is charged again, This cycle forms an oscillation. The charging time is: 0.695(R11 R12 R13)C2, and the discharging time is: 0.695(R13 R12)C2. Adjusting R13 can control the output frequency of the oscillator. The clock oscillation signal of NE555 is constantly added to pin 14 of CD4017. There are 10 LEDs connected to the 10 output terminals of the CD4017. When the 10 output terminals of the CD4017 generate high levels in turn under the action of the clock signal, D1--D10 will be lit in turn to form a water lamp effect. Adjust R13 to adjust the flow speed of LED lights.
Common problem:
1. Take care to avoid wrong welding of the positive and negative poles of the LED, and the long leg is the positive pole.
2. Take care to avoid wrong welding of the positive and negative electrodes of the electrolytic capacitor, and the long leg is the positive electrode.
3. Take care to avoid inserting the chip in the opposite direction. The chip notch and the base notch should be in the same direction as the notch on the board.
4. Take care to avoid wrong connection of the positive and negative poles of the power supply. The correct connection method is to connect VCC to the positive pole, GND to the negative pole, and supply a 3-5V DC voltage.
Pay attention to check the welding for short-circuit and virtual welding.
