Battery Protector Low cut off-Designed for Driving Lights.

Description This unit is a MICRO VSR Voltage Sensitive Relay Module designed with an LED indicator and an aluminum heat sink How to work: The VSR is connected between the positives of the main and load (DRL, etc.) and works according to the voltage. When the engine is started and battery reaches 13.2 V, the VSR engages, allowing currant through to the load. When the engine is stopped and voltage drop to 12.8volts, the VSR disengages, separating the battery and load. This system eliminates the possibility of draining the battery.
