Large Current 5A Constant Current Constant Voltage LED Drives Lithium Battery Charging XL4015 Module

A buck converter with adjustable current limit as well as adjustable voltage, which is what makes it suitable for charging lithium batteries and driving LEDs rather than just powering circuits. Constant current then constant voltage is exactly the charging profile a lithium cell requires. Set both the voltage and the current limit carefully before connecting a battery — an incorrect charge voltage on a lithium cell is a genuine fire risk, not merely a performance problem. Adjustable current limit as well as voltage; Correct CC-CV profile for lithium charging; 5A capability for high power LED driving; Onboard indicator shows charging state
