4pcs XH-M609 Low Voltage Cutoff, DC 12V-36V Voltage Protection Digital Display Switch Module Over Discharge Protection Low Voltage Protector Disconnect Switch Module

XH-M609 Low Voltage Cutoff Specifications:Supply voltage: 12-36V batteryOutput voltage: equal to the supply voltageControl accuracy: 0.1VPower: ＜1.5WScope of application: various batteries lithium batteryNet weight: approx. 28g / 1.0ozProduct size: approx. 57*42*19mm / 2.2*1.7*0.7inHow to use:The first time a new battery is used, the rated voltage value is close to the actual value, Judgment to stop the discharge voltage.A reasonable discharge voltage value can be obtained according to the general voltage calculation method of the battery.When the old battery is used, the actual voltage value and the rated voltage value are quite different, so you need to measure the stop voltage value in actual use.Battery charging usually uses slow charging (the voltage and current of fast charging are relatively large, and the battery is easily damaged.)The charging voltage of slow charging is 1.2 times the rated voltage, and the charging current is adjusted to about 2/10 of the rated capacity current of the battery.For example: the charging voltage of a 6V 50Ah battery is about 7.2V, adjust the charging current to 10A

• Low Voltage Disconnect Module XH-M609 12-36V Battery Low Voltage Cutoff Protection Module Over-Discharge Protector for Solar Panel Lead Acid Lithium Battery
• Efficient Low Voltage Protection Against Over-Discharge: The XH-M609 module automatically disconnects the load when the battery voltage drops below the set threshold, preventing over-discharge and safeguarding your battery
• Easy Reset Operation: When the power is off, press and hold both buttons at the same time, then power on, the screen will show "888" to indicate the successful restoration of factory settings, the factory set protection value is 12V, the difference is 2V
• Accurate Voltage Monitoring with Simple Operation: Features an LED digital display for real-time voltage monitoring with 0.1V precision, allowing easy setup of low voltage protection levels
• Extends Battery Life with Reliable Performance: By cutting off the load in time, it prevents deep discharge, ensuring long-term stability for lead-acid or lithium batteries
