Relay closes when voltage ≥ P2 (upper limit) and opens when voltage ≤ P1 (lower limit). Setting the Limits (P1 & P2)

Integrated voltmeter, undervoltage/overvoltage protection, and a timing discharge function. 2. Wiring Guide

The relay on the board should be placed "in-line" with one of the wires (typically the positive) of your charger or load. Xh-m608 Manual

Sets the trigger for stopping a charge or starting a discharge.

The relay does not function; it only displays the current voltage. Relay closes when voltage ≥ P2 (upper limit)

Relay closes when voltage ≤ P1 (lower limit) and opens when voltage ≥ P2 (upper limit).

When the battery is low, the relay closes to allow the charger to work. When full, it opens to prevent overcharging. Wiring Guide The relay on the board should
