Our unique production method using the battery charge gauge, based on the discharge curve to calculate the remaining battery power, is a truly accurate gauge, with its unique design makes high reliability, accuracy, user monitor the battery power changes. 

 Multi-color LED displays battery 10. 
 70% of battery discharge, the red LED flashes issued a "reserve power" warning. 
 Discharge 80%, two red LED flashes, issued a "battery depleted" alarm. 
 "False" charge recognition. 
 When the battery discharges 80%, the signal output terminal voltage from 5.0 ± 0.5V down to 0.0 ± 0.5V, it can output signals to other parts of the vehicle or against a specific operating functions, to prevent deep discharge. 

 Monitoring equipment used for life time. 
 LCD display to 99,999.9 hours total time, tired, and continue to automatically reset when the total time and display. 

 Compact, easy to install.
