PREVENTING OVER-DISCHARGE: This battery controller provides extensive flexibility in discharging modes and parameter settings. Users can set parameters to automatically disconnect the battery when it reaches a preset voltage, thus preventing over-discharge and prolonging battery life (Note: The relay doesn't have a power cut-off switch. Remember to cut off the power supply after disconnection; otherwise, the module will continue to use the battery until the voltage is 0. ). The customizable parameters allow users to adapt their power management system to specific needs and preferences ^^
EASY OPERATION: To restore factory settings, turn off the device, press and hold both buttons simultaneously, and then turn it on. The screen will show "888", indicating that the factory settings have been restored. The default protection value is set at 12V with a difference value of 2V. The difference value represents the voltage range between disconnecting and reconnecting the battery. User settings are retained in case of unexpected power loss, ensuring critical data is saved and allowing for seamless resumption of operations ^^
Application Scope: This device is a voltage controller that uses a relay to switch the output on and off. The relay only acts as a switch and doesn't change the voltage. It is a protective switching module and doesn't include batteries. Compatible batteries include lead-acid, lithium-ion, and solar panel batteries. This module isn't suitable for battery packs ^^
NOTE: Due to the size limitations of the PCB board, this module has a miniaturized relay and thin circuit lines. Therefore, the current during actual use should not exceed 8A to avoid damage to the relay contacts. The maximum current is 10A when the voltage is below 12V, and it should be less than 8A when the voltage exceeds 12V
