The voltage reading is accurate and gives a much better idea of battery health compared to the stock bar indicator. The blue display looks clean and matches well with modern setups. Installation is simple (just 2 wires), but make sure you connect it to a switched power source (key ON). If you hook it directly to constant power, the screen will stay on and drain your batteries over time. Also note: if you’re replacing a factory meter, some of those wires may be part of other circuits (like lights), so double check before disconnecting anything. Overall, solid upgrade and very useful for diagnosing battery performance under load.
