1.2-34V 5A DC-DC Step-down CC/CV XL4015 Battery Charger LED Driver with Volt, Amp & Power Meter

This XL4015-based voltage converter is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module with Constant Voltage and Constant Current control, capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation. It is a very flexible and adaptable charging solution that can provide either a Constant Voltage (CV) or Constant Current (CC) output. With a variable output voltage range of 1.2V to 34V and variable output current from 0A to 5A peak (4A continuous), it is ideal for use as an LED or laser diode current source/driver, a battery charger, a lab current/voltage source, or to regulate the output of solar panels or wind turbines to charge energy storage batteries. It can charge most any size lithium-ion cell to almost any voltage you need. This is an inexpensive way to charge those 4.30V and 4.35V cells, as well as LiFePo and many other cells that require different termination voltages. It is also a good way to charge smaller cells since you c
