Reviews Seven Segment Led Display

Jialan 48V Battery Fuel Gauge Indicator,for Golf Cart,EZGO, Yamaha, Fork Lifts,Club Car,Floor Care Equipment LED Battery Indicator Meter Gauge

【48V Battery Fuel Gauge】This device is only workable on lead-acid battery but not Trojian type.LED battery indicator available in 48V volt DC acid battery.
【LED Battery Indicator Meter】10 segment LED Bar Graph display,Resolution: 10% per segment：3 color LED display,different light displays different battery level visually.
LED flash for low charge&high charge warning.
【Note】The second LED from the left flashes as a warning that the batteries voltage has been discharged to 80% of their capacity.It is strongly recommended to recharge the batteries when you get to the 3rd Yellow LED, this is a safety precaution to avoid dead batteries.
【 Installation Notes】Make sure your "C" terminal is either connected to the Battery "+" or a Key switch, Meter will scan from full to empty then shuts off .Meter will stay full position while first is connected with batteries and indicate the actual battery level after 155 seconds..
【 Battery Indicator】LED battery indicator battery fuel gauge battery charge gauge for DC powered equipment such as fork lifts, golf carts, floor care equipment, and any other battery powered.
