Company producing battery charge gauge uses a unique algorithm based on the battery discharge curve to calculate the remaining capacity is a true and accurate charge gauge, it is designed to have high reliability, accuracy, user-friendly monitoring battery power changes. 
 Red 10-segment LED shows the battery power. 
 Battery discharge 70%, the red LED flashes issued a warning of the "power reserve". 
 Discharge 80%, two red LED flashes, the issue of "Battery depleted" alarm. 
 "False" charge recognition. 
 When the battery discharges 80%, the signal output terminal voltage decreased from 5.0 ± 0.5V to 0.0 ± 0.5V, it can be for other parts of the output signal or prohibit vehicles from a particular operating function, to avoid a deep discharge. 

 The compact, easy to install.
