12V Battery Protection Auto Cut-Off Circuit – Adjustable Charging Controller
The 12V Battery Protection Auto Cut-Off Circuit is a relay-based voltage control module designed to automatically switch a compatible 12V battery charging circuit on or off according to the battery voltage. It helps control the charging process by disconnecting the charger at a preset upper voltage and allowing charging to resume when the voltage falls to a lower setting.
This module features an onboard voltage adjustment control and indicator LEDs. It can be useful for compatible 12V battery charging projects, DIY electronics, and battery charging control systems when installed according to the correct wiring diagram.
Key Features
- 12V Battery Charging Control: Designed for compatible 12V battery charging circuits.
- Automatic Cut-Off: Disconnects the charging supply when the configured upper voltage threshold is reached.
- Automatic Restart: Allows charging to resume when the battery voltage reaches the configured lower threshold.
- Adjustable Voltage Settings: Onboard potentiometers allow voltage thresholds to be adjusted, depending on the board version.
- Relay-Based Switching: Uses a relay to control the connected charging circuit.
- LED Indicators: Visual indicators are provided on the pictured board; confirm their meanings against the actual board.

Installation and Safety Notes
- Verify the circuit diagram, terminal labels, and voltage settings before connecting the module.
- Confirm that the battery chemistry and charging method are compatible with the module and charger.
- Do not assume the module provides deep-discharge protection for a connected load; its advertised function is charging cut-off control.
- Do not exceed the verified relay current, voltage, or power ratings. The relay rating must be confirmed before connecting a high-current charger.
- Disconnect power before wiring or adjusting the circuit. Incorrect connections can damage the board, charger, or battery.
Package Includes
- 1 × 12V Battery Protection Auto Cut-Off Circuit Board
