Adjustable 12–36V DC Battery Low-Voltage Protector Relay Module
This digital battery protection module monitors DC voltage and disconnects the output when the battery reaches the selected protection level. The disconnect and reconnect voltages can be adjusted using the onboard buttons, while the digital display provides a clear voltage reading.
It is suitable for lead-acid, lithium-ion, and solar battery systems requiring adjustable over-discharge protection. The relay switches the output on or off but does not convert or regulate voltage. For reliable operation, keep the actual current below 8A as recommended in the product specifications.
The module continues drawing power after the output is disconnected, so the main power supply should be switched off when required. It does not include a battery and is not designed for battery packs.
