NOTE: This 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. It's a protection switch module, not included batteries itself.

OVER DISCHARGE PROTECTION: This battery controller provides a high degree of flexibility in terms of discharging modes and parameter settings. Users can easily set the parameter to disconnect the battery automatically when it reaches a preset voltage, thus preventing over-discharging and extending battery life. With its customizable parameters, this battery controller allows users to tailor their power management system to their specific needs and preferences.

MEMORY FUNCTION: With power-off protection, it will save your settings in the event of an unexpected loss of power. This feature is crucial for electronic devices that require specific configurations, as it prevents the loss of critical data and allows you to resume work where you left off.

DELAY TURN-ON: That means, after a disconnect, the interval between turning on again. The time range that can be set is 0-999 seconds
