(Note: Due to the limitation of the size of the PCB board, the relay size of this module is mini and the circuit lines are very thin. The current should not be too large during actual use. If the current exceeds 8A, the relay contacts may be blown.)
Wide Applications: Programmable battery low voltage disconnect switch for DC12-36V lead acid battery and lithium ion battery. It's a protection switch module, not included batteries itself. Compatible Battery: lead acid, lithium ion battery, solar panel battery. Not suitable for battery packs.
Usage Method: On-board momentary push button to set the low voltage disconnect parameter and 3 digit red LED display the parameter easy to operation. When the battery voltage reach the setting values, the module will disconnect load automatically to aviod the battery from over discharging to prolong the battery lifetime. (Note: The relay does not contain a power cut-off switch, remember to cut off the power supply after disconnection, otherwise the module will continue to use the battery until the voltage is 0.)
Reset: When the power is off, press and hold the two buttons at the same time, and then power on. The factory-set protection value: 12V, difference value: 2V.Difference Value""is the value between the battery voltage to disconnect and the battery voltage to reconnect.
Advantage: 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.

Package Included: 2Pcs Voltage Protection Module
