NOTEThis product is a voltage controller, which turns on and off the output through a relay, which only acts as a switch and cannot change the voltage.CHARGE AND DISCHARGE PROTECTIONYou can freely set the charging or discharging mode and set parameters. For example, when the battery voltage reaches the set voltage, the module will automatically disconnect to avoid battery over-discharging and prolong battery life; In addition, you can also set the charging and discharging timeLCD SCREENUnlike other LED display modules, this protection module comes with an LCD high-definition display, which can clearly display voltage, voltage percentage and time30A CURRENTWith 30A high current relay, suitable for any 6-60V variety of batteries and Lithium batteriesDELAY TURN-ONThat means, after a charge or discharge, the interval between turning on again. The time range that can be set is 0-999 seconds
