The installation process is relatively cumbersome and it is not convenient to quickly connect and fix the monitoring device to batteries of different sizes. Utility Model Content

Then one end of it passes through the wire groove and the screw is turned to connect one end of the No. 2 wire to the conductive base, so that the conductive plate is electrically connected to the No. 2 wire. Then one end of the main wiring harness is passed through the wire groove and the screw is turned to electrically connect one end of the main wiring harness to the conductive base, so that the monitoring mechanism is electrically connected to the main wiring harness. When it is not necessary to detect each battery block, turn the screw in the opposite direction to remove the corresponding No. 2 wire below it and clamp it inside the wire clamp, so as to quickly adjust the number of connections between the monitoring device and the battery block according to monitoring needs, making the monitoring device easier to operate.
