When charging batteries, always install a blocking diode on the OUT+ line. Without it, the battery can feed power backward into the module and burn it out once the input power turns off. Common Troubleshooting Steps Potential Cause Display does not light up Input voltage is below 8V or polarity is reversed. Check input source with a multimeter. Output voltage drops under load Input power supply is hitting its current limit. Upgrade to a higher-wattage input power supply. CC LED turns on unexpectedly The load is drawing more current than your setting. Increase the current limit if your load safely allows it.

When you first power on the device, it displays the default view.

Verify input voltage with a multimeter. Ensure IN+ and IN- are correct. Check the input fuse. bst900w manual

Illuminates when the module is successfully regulating a fixed voltage.

Press and hold OK to activate output. Ensure target voltage is configured higher than input voltage. When charging batteries, always install a blocking diode
