1.Fixed turn the lamp current to 0.1 times the value of the constant current (charge when used to identify whether the battery is full);
2. Increased input reverse polarity protection diode;
3. Increase the output of a backflow preventing diode to prevent when the electricity to charge the battery back in;
4. Using dedicated reference IC, and high-precision sampling resistor, so that the constant current is more stable, (20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1%).

Battery use:
l Make sure of the voltage and current of the battery you need to charge
l Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
l Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease)
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected charging current value
l The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
l Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries)
LED Constant Current Driver Use:
l Make sure operating current and Max operating Voltage of the LED you need to drive
l Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer
l to make sure the output current to the expected LED operating current
l Join LED, test (For the above 3 steps, module input terminal is connected to power source, output load is NOT connected to LED)
