Description
XL4015 5 A CC-CV Step-Down Converter
This XL4015 buck module provides adjustable output voltage and constant-current limiting. The source describes blue and green indicators for charging status, but indicator behavior alone is not a safety-certified method for confirming that a battery is fully charged.
Applications listed by the source
- Powering high-power LEDs that require constant current
- CC/CV power-supply projects
- The source mentions battery, solar-panel and wind-power uses; verify the system requirements before use

Important battery and setup safety
The source specifications disagree on the input and output voltage limits. Verify the exact board revision and its datasheet before applying power; do not assume the higher values are safe. This CC/CV module is not a chemistry-aware battery charger and does not replace a dedicated charge controller, battery protection, balancing or temperature monitoring. Use a charge profile and independent safeguards appropriate to the specific battery. No input reverse-polarity protection is specified. Set and verify voltage/current limits before connecting a load.
