10 Best Battery Over Discharge Protection In The Us - Black Friday 2024
2 PCS Low Voltage Cutoff, Icstation DC 12V-36V Low Voltage Disconnect 20A Over Discharge Protection Low Voltage Protector Disconnect Switch Module for Lead Acid Lithium Battery Solar Panel Light
Main highlights- PARAMETER: Board Size: 57 x 42 x 19mm/2.24 x 1.65 x 0.75inch(L*W*H); Input Voltage: DC 12-36V; Accuracy: 0.1V; Power Consumption: <1.5W; Maximum Amperage before Breaker Trips: 20A
- OVER DISCHARGE PROTECTION: This battery controller provides a high degree of flexibility in terms of discharging modes and parameter settings. Users can easily set the parameter to disconnect the battery automatically when it reaches a preset voltage, thus preventing over-discharging and extending battery life. With its customizable parameters, this battery controller allows users to tailor their power management system to their specific needs and preferences.
- NOTE: This product is a voltage controller, which turns on and off the output through a relay, which only acts as a switch and cannot change the voltage. In addition, if you have any questions in use, please let us know at the first time.
- MEMORY FUNCTION: With power-off protection, it will save your settings in the event of an unexpected loss of power. This feature is crucial for electronic devices that require specific configurations, as it prevents the loss of critical data and allows you to resume work where you left off.
- DELAY TURN-ON: That means, after a disconnect, the interval between turning on again. The time range that can be set is 0-999 seconds

Main highlights- Reset:When the power is off, press and hold the two buttons at the same time, and then power on. At this time, the screen displays "888", indicating that the factory settings are restored.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.
- 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.
- Package Included:4x Protection Module.
- 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.)
