ICSTATION Digital Low Voltage Protector, DC 12-36V 20A Low Voltage Cutoff Disconnect Switch Over-Discharge Protection Module for Lead Acid Lithium

The Voltage Protector is an efficient and effective device for preventing DC operation beyond its specified limit. It is also capable of switching off the current supply to protect connected devices from being damaged due to low voltage input. With a limit of 20 amps, the protector can support a range of devices without any issues. It is also possible to use the protector with AC power at the inverter output. However, a dedicated DPDT relay is necessary to ensure that the pilot relay is only engaged when the DC voltage level reaches a specific level. The protector also comes with a programmable feature that allows users to set the desired voltage value that triggers the cutoff switch. The device can be adjusted to a 12.4V cutoff point, and there is an option to set the reconnect voltage offset as well. The protector also has a low idle current draw of approximately 5mA, ensuring that it doesn't drain the battery even if there's no load present on it. While the Voltage Protector has specific features that make it excellent for specific applications, it's not without its flaws. The mounting holes are relatively small, which can be problematic for users who might require larger screws to secure the device in place. Additionally, some buyers received an unexpected board that has lower specs and quality components than what was advertised. Finally, some users report the built-in relay can smoke and become useless in a week when used with Power Wheels, and an external automotive relay becomes necessary.
