LM2596 DC DC Step Down Adjustable CC/CV.

LM2596 DC DC Step Down Adjustable CC/CV Fix turn the lamp current to 0.1 times the value of the constant current (charge when used to identify whether the battery is full);- Increase input reverse polarity protection diode; .Using dedicated reference lC, 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%)

·Particularly suitable for LED driver ·High-power LED constant current drive . Lithium battery charger (including ferroelectric).4V,6V,12V,14V,24V battery charger . Nickel cadmium,

nickel metal hydride battery pack charger . Solar panels and wind turbines

A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low small batteries  to very high (high-voltage power transmission).

Make sure of the voltage and current of the battery you need to charge; ·Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage; – 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.

The charge current of transfer lamp is default 0.1 times of the charging current (constant current value); ·Connect to the battery and try to charging (for previous 5 steps, module input terminal is connect to power source, output load is NOT connect to batteries).en.wikipedia.org
