Turn clockwise to reduce the charging voltage, and counterclockwise to increase it. Note that when adjusting the charging voltage, the charging voltage keeps jumping. This is a pulse voltage output by the charger when it automatically detects the battery. Just adjust the highest jumping voltage to a suitable value.

The module has a wide input voltage range, supports lead-acid batteries, lithium-ion, lithium polymer, and lithium iron phosphate batteries as backup batteries. It has a complete charge management function. At the same time, the on-board automatic voltage regulator circuit can directly provide voltage regulation After the DC power supply to the device. When switching between the input power supply and the battery, the output voltage is stable and the load is not affected in any way.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003eWhen the input power is on, the module will charge the battery and at the same time output the regulated power to the device. When the input power is cut off, the module automatically switches to battery power supply and provides a regulated power supply to the device. The switching time is zero and the load operation is not affected. When powered by a battery, the on-board MCU will monitor the battery voltage in real time. When the battery is discharged to the set under-voltage threshold voltage, the power supply will automatically turn off the output and enter a low-power sleep mode. The power supply can only be started when the input is re-powered or the battery voltage returns to the start-up threshold voltage.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003ePlease note that the charging part of this module is for step-down charging, and the input power supply voltage must be 1V higher than the charging cut-off voltage of the battery to be charged. For example, if the battery uses a 12V lead-acid battery, and its charge cut-off voltage is 13.8V, the input power must be a DC power supply between 14.8V and 28V.
