About this item OVER-DISCHARGE PROTECTION: This battery controller offers extensive flexibility in discharging modes and parameter settings. Users can configure parameters to automatically disconnect the battery when it reaches a preset voltage, thereby preventing over-discharge and extending battery life. The customizable parameters enable users to tailor their power management system to specific requirements and preferences. SIMPLE OPERATION: To restore factory settings, power off the device, press and hold both buttons simultaneously, and then power on. The screen will display '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 the event of an unexpected power loss, ensuring critical data is preserved and allowing seamless resumption of operations. SCOPE OF APPLICATION
