This module features charge & discharge protection with a 5V–60V DC input and a maximum 40A current rating. It supports zero standby power consumption under manual mode, and allows seamless switching between manual and automatic working modes. Additional built-in functions include charge/discharge timing control, programmable power on/off delay, 60-second automatic LED screen shutdown, and customizable forced startup time.

CORE FUNCTIONS / KEY FEATURES

● It has a 2-in-1 charging mode (battery overcharge protection) and discharging mode (battery low voltage protection). The charging mode can be used for solar charging, and the battery automatically disconnects when it reaches the set voltage. The discharging mode can be used for battery low voltage protection.

● Two low-power modes: automatic mode and manual mode. Manual mode consumes 0 power after the relay disconnects, and manual button reset is required after disconnection;

● In automatic mode, the relay enters a low-power mode after disconnecting (LED turns off after 60s without any button action, and the LED resumes display when a button is pressed again). Standby current is 5mA (18V), and it automatically restarts when the voltage is restored.

● The device has an internal flash storage module, so all settings can be restored after a power off.

● Maximum 40A current, operating voltage from 5V to 60V.Supports a 99 seconds start delay, 99 seconds disconnect delay, and a 99:59:59 hours timer disconnect timer.

WARNING

● Please make sure that "IN+ IN- OUT+ OUT-" and the positive and negative poles of the battery cannot be reversed. Reverse connection will damage the product, battery and charger;

● The charging mode and discharging mode need to use the button setting to switch the mode before use. See the description below for the switching method.

● It is a charging/discharging controller but not a charger or voltage converter
