2PCS Low Voltage Cutoff, DC 12V Low Voltage Disconnect Switch Cut Off, Low Voltage Protector Over Charging Discharging Protection Module, Battery Charging Control Board Switch with Digital Voltmeter
LOW VOLTAGE CUTOFF: This is a voltage protection module and does not include a battery! The output is turned on and off via a relay, which only acts as a switch and cannot change the voltage. (Note: It is only suitable for detecting pure DC voltage, please do not use it to detect AC voltage! )
INDEPENDENT WORKING VOLTAGE: To avoid draining the voltage of the battery under test, the device can be connected separately to another power source as its working voltage. Working Voltage: DC 12V. Measure Voltage: DC 0-99.9V.
7 WORKING MODES: Charging monitoring, discharging monitoring, out-of-range engagement, in-range engagement, fixed-point monitoring, fixed-point self-locking monitoring, and fixed-point pulse monitoring. Low voltage protector for lead acid, lithium ion battery, and solar panel battery. (Note: Applies to individual cells only, not battery packs.)
OVER DISCHARGE CHARGE PROTECTION: You can choose charging or discharging mode and set parameters according to your needs. When the measured voltage reaches the set voltage, the low voltage battery protection board will automatically disconnect to avoid battery overcharge or over-discharge and extend battery life.
MEMORY & RESET FUNCTION: Press the "SET" button for the fourth time to permanently save the parameters and exit! Prevents the loss of critical data and allows you to continue where you left off. Additionally, in standby mode, press the "-" button for 3 seconds to turn off the display, and press for another 3 seconds to turn on the display.
