• Battery Protection: The dual mode battery charge/discharge control protector safeguards your battery from over-charge and over-discharge, and ensures its longevity. when the battery voltage reaches the set level, the module will automatically disconnect to prevent over-discharge and extend battery life.
• High Current Capacity: With a 30A high-current relay, this module is suitable for a range of 6-60V batteries, including Lithium batteries, and is ideal for use in various applications such as solar and wind power systems and new energy vehicles.
• Clear LCD Display: The high-definition LCD screen displays real-time voltage, percentage, and time, making it easier to monitor battery conditions.
• Customizable Settings: Customize charging time and delay time (0-999 sec), forced turn-on time (0-10 sec) to prevent misoperation due to voltage fluctuations. Also, program battery stop and start values, and enable power-saving mode.
• Voltage Controller Functionality: This product is just a voltage controller that turns the output on and off through a relay, acting as a switch only, and is not capable of changing the voltage.
