Check battery status at a glance! You can build this kit to monitor 5, 8, or 12V DC power supplies (optional parts supplied) and you can set the LEDs to indicate .25, .5, or 1V steps. SIZE: 1.3" x 2.7". Current usage depends on the voltage and the number of LEDs lit (typical 80mA at 12V) but you can easily add a pushbutton switch on the input-- push and check!
