Review on 48V Trojan Battery Indicator Meter LED Display Golf Cart Battery Gauge for EZGO Club Car Yamaha Golf Cart (Trojan Batteries Only) by Robert Morrison

Does not indicate full charge at 51.6V measured on the display. The 7th segment lights up, indicating a 70% change. (7th of 10 segments on display) Solder, do not attempt to crimp the spade connectors provided. The box packaging is a good template for cutting out the mounting hole. Update: The attached schematic doesn't work. First I connected the + wire directly to the battery according to the diagram. The display does not measure or update correctly. I then connected the + and C wires together and routed them through the main switch so that it turns on and off with the switch. Now it updates every time I turn on the switch and everything works fine.
