### Product Introduction
Tired of replacing lithium batteries damaged by over-discharging? Our XH-M609 Low Voltage Disconnect Switch is the perfect cost-effective solution for 12V to 36V lithium battery protection, with smart programmable settings and intuitive digital LED display. (Batteries are not included, this is a protection module only)
#### Key Advantages
1. Wide Adaptability: Works for all 12V-36V lithium ion battery applications, output voltage matches input voltage directly, no extra wiring modification needed for most scenarios.
2. User-friendly Operation: Equipped with tactile push buttons and high-brightness 3-digit red LED screen, you can adjust and view all parameters in seconds, no professional skills required.
3. Smart Battery Guard: Once battery voltage drops to your pre-set low value, the module disconnects the load automatically to avoid irreversible over-discharge damage, greatly prolonging your battery's service life.
4. Stable & Durable: Delivers 0.1V high display and control accuracy, with only ±0.1V maximum voltage error, and ultra-fast switching response when voltage hits the threshold. All custom settings are saved permanently even after power cut, no repeated setting needed.

#### How to Set Up
1. To set cut-off voltage: Double tap the "+" key, then press "+" or "-" to adjust to your desired low voltage cut-off value.
2. To set reconnection voltage: Double tap the "-" key, then press "+" or "-" to adjust to your desired voltage recovery value.
3. To calibrate voltage display: Single press the "+" key, then use +/- keys to align the displayed value with actual input voltage.
4. To set start delay: Single press the "-" key, then use +/- keys to set delay time T (range 0-10 minutes, optional options: 0min, 1min, 5min, 10min, shown as 000/001/005/010). Output will turn on after T minutes once battery voltage reaches the reconnection value.
5. Short press "+" to view saved cut-off voltage, short press "-" to view saved reconnection voltage.
6. The gap between cut-off and reconnection voltage supports 0.5V to 48V adjustment range.
*Sample Setting: If you need the battery to stop supplying power below 11V and restart when voltage is above 11.6V: Hold "+" to set cut-off voltage to 11, wait for LED to stop blinking, then hold "-" to set the difference value to 0.6V.
#### Warm Tips
1. The display images do not reflect actual size, please check the listed size data before purchasing.
2. Slight measurement error (within 2mm) is normal due to manual measurement, thanks for your kind understanding.
3. The actual color of the product may have minor difference from the pictures due to different display screen calibration settings.
