Simply set the desired charge voltage and current limit using the onboard potentiometers and verify with the digital display before connecting your battery.\u003c\/p\u003e\n\u003ch4\u003eQ: Why is a 72V battery not compatible with this module?\u003c\/h4\u003e\n\u003cp\u003eA: While the input voltage range is rated up to 80V, 72V lithium battery packs can spike above 80V at full charge, which may exceed the module's maximum safe input voltage. To protect the module and your application, the manufacturer specifically excludes 72V battery systems from the supported configurations.\u003c\/p\u003e\n\u003ch4\u003eQ: What wire gauge should I use for high-current applications near the 20A rating?\u003c\/h4\u003e\n\u003cp\u003eA: For continuous loads near 20A, a minimum of 12 AWG wire (or equivalent metric gauge) is generally recommended for short runs. For longer wire runs or near the 25A peak, consider 10 AWG or thicker. Always use wire rated for the temperature and current demands of your specific setup.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this power module require a heatsink or cooling fan?\u003c\/h4\u003e\n\u003cp\u003eA: At lower power levels the board operates efficiently with minimal heat. For sustained high-power operation (near 600W \/ 20A), adding an external heatsink to the main switching components or directing airflow across the board with a small fan is strongly recommended to maintain optimal efficiency and long-term reliability.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Can this adjustable buck power module charge lithium or lead-acid batteries?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes — because the module supports both Constant Current (CC) and Constant Voltage (CV) modes, it is well suited for charging lithium-ion, LiFePO4, and lead-acid battery packs.
