12V BATTERY INDICATOR BOARD MODULE LOAD 4 DIGIT ELECTRICITY INDICATION WITH LED LAMP

This is Four Battery Indicator LED Light XD-82B 12V Battery Level Indicator Module. This module has on-board precision voltage detection chip and power regulator chip. And on-board four battery indicator LED lights, three colours display, red, yellow, yellow, green representing 20%, 50%, 80% and 100% of the electricity. You can set aside all the way battery testing interface, and two mounting holes located. This module is ideally suited to monitoring the status of a 12V battery. Through clever use of a series of resistors and the LM339 comparator, a visual indication of the state of a battery can been seen. As the battery depletes and the voltage begins to fade lights will begin to go off.
