XHM609 Low Voltage Disconnect Switch Cut Off Protection 12V 36V Lithium Battery

*Programmable battery low voltage disconnect switch for DC 12-36V battery and lithium ion battery. It's a protection switch module, not included batteries itself.

*On-board momentary push button to set the low voltage disconnect parameter and 3 digit red display the parameter easy to operation.

*When the battery voltage reach the setting values, the module will disconnect load automatically to avoid the battery from over discharging to prolong the battery lifetime.

*Display is accurate, the switch module is quickly to open and close when near minimum voltage; Settings is stored non-volatile, it can keep set when power off.

*Applicable to all applied voltage range of electric two-wheeled tricycle battery, car battery and new energy electric vehicle battery discharge protection.

*The indicator light is on and there is voltage output at the output terminal. When the indicator light is off, there is no voltage output at the output terminal

Set up usage: Set to stop below 12.5V and start above 14V: Set protection value: Press the "+" once to display the protection value, double-click the "+", the decimal point will flash, and then press the "+" or "-" to change the value to 12.5. If there is no operation for 3 seconds, the module will automatically save and exit the setting mode. Set hysteresis value: Press the "-" once to display the hysteresis value, double-click the "-", the decimal point flashes, and then press the "+" or "-" to change the value to .5. If there is no operation for 3 seconds, the module will automatically save and exit the setting mode. Set to stop below 10V and start above 15.5V: Set protection value: Press the "+" once to display the protection value, double-click the "+", the decimal point will flash, and then press the "+" or "-" to change the value to 12.5. If there is no operation for 3 seconds, the module will automatically save and exit the setting mode. Set hysteresis value: Press the "-" once to display the hysteresis value, double-click the "-", the decimal point flashes, and then press the "+" or "-" to change the value to .5. If there is no operation for 3 seconds, the module will automatically save and exit the setting mode. Restore factory settings: When the power is disconnected, press and hold both buttons at the same time, and then turn on the power. At this time, the screen displays "888" to indicate that the factory settings have been successfully restored. Factory set protection value: 12V, hysteresis value: 2V

Usage method: When a new battery is used for the first time, the rated voltage value is close to the actual value. To determine the stopping discharge voltage, a reasonable discharge voltage value can be obtained based on the general voltage calculation method of the battery. When using old batteries, there is a significant difference between the actual voltage value and the rated voltage value, so it is necessary to measure the termination voltage value yourself during actual use. Slow charging is commonly used for battery charging (fast charging can result in high voltage and current, but can easily damage the battery). The voltage for slow charging is .2 times the rated voltage, and the charging current should be adjusted to about 2/10 of the rated capacity current of the battery. For example, the charging voltage of a 6V 50Ah battery is around 7.2 volts, and the charging current is adjusted to 10A. Reference : Charging voltage=Rated voltage x . for 2 Charging current=Rated current x 0.2
