The ENM Battery Discharge Gauge PT271AB1 is a complete solid state battery discharge fuel gauge and hour meter in one. The battery gauge (BDI) is a 10 bar multi color LED display state of charge indicator. It is ideal for electric vehicles application.

NOTE: The (Green and White wire) input sensing voltage connection should be as close to the battery as possible for accurate discharge inductor reading. When low voltage battery (Green wire) is in use the high voltage battery input (White wire) is left open and vise versa.

Please note: This part is only available in increments of 25. Price is per unit.
