Works on most standard lead acid batteries. Check the voltage range below for compatibility before ordering.

Battery Range for 12 Volts – 10.98 volts empty; 12.48 volts full.

Battery Range for 24 Volts – 21.96 volts empty; 24.96 volts full.

Internal relay puts out 4.5 volts DC to power external solid state relay (not supplied) to power auxiliary equipment.

Relay shuts off when the #1 and # 2 LEDs are alternately flashing.

Battery Status The battery meter has 10 LEDS that will light to show the battery condition. When fully charged, only the 10th LED will light shown a green LED. As the battery discharges, successively lower LEDs will light; the 9th, 8th, 7th and so on lighting only 1 LED. At approximately 30{4f68e189d3cf4e3ebdda5133e35265d735149066fae22641530f59a80cc6d0de} battery life, the #3 LED will light and the color is Yellow as a caution indicator.

At approximately 20{4f68e189d3cf4e3ebdda5133e35265d735149066fae22641530f59a80cc6d0de} battery life remaining, the #2 LED will light as a Flashing Yellow. When the battery discharges to approximately ~10{4f68e189d3cf4e3ebdda5133e35265d735149066fae22641530f59a80cc6d0de} remaining life, the #1 LED will start FLASHING RED with the #2 LED FLASHING Yellow alternately.
