The Tenergy Cell Meter is a handy little device that allows you to monitor your Li-Po and Li-Ion batteries to keep them in good condition.  It features several functions designed to give you the information you need to prevent over-discharge of your batteries during use, and over-charging of your batteries while being charged.


During use , the alarm function will sound a loud buzzer and illuminate the 10mm red LED to indicate that the battery is getting low.  It allows the user to set the low-voltage threshold between 3.0V to 4.0V per cell.  If the voltage of any one of the cells of your battery drops below the threshold value, the alarm will sound and the LED will flash, indicating the need to re-charge. Because of its light weight and compact design, you can attach it to your model and leave it in place during flight.


During charging, the alarm will sound if the battery’s voltage exceeds 4.22V per cell, or if it drops below the threshold value. In addition, Tenergy Compact Cell Meter can supply a valid PWM/PPM signal for testing servos.
