When using the module to charge batteries, always connect the input power source before attaching the battery to the output terminals . Ensure the output voltage is configured higher than the battery's voltage before turning the output on to prevent reverse currents from damaging the buck-boost stages. 3. Basic Operation & Display Modes When powered on, the displays the Normal Interface .
