Lipo Battery Voltage Checker and Alarm, 2 Pack - LED Detector for 1S-8S Lithium Batteries 1655

Product description This checker will work on almost any 1-8S lipo battery. It reads individual cell voltages, and whole pack voltage.There is an alarm that will buzz when reach the low voltage point，which is incredibly useful during flight when light indicators are not visible. There is also a low voltage alarm that will sound when the pack gets too low. The alarm voltage can be set by pressing the button on top of the unit. The voltage the alarm will sound is adjustable between individual cell voltages of 2.7v and 3.8v in .1v increments (3.3v is the default). How to use: Insert the electric front side up (digital side), insert it for yourself, insert the white balance charging plug of the battery along the leftmost pin of the electric display, and the electric display will immediately ring BB twice, and the number of jumps will be displayed on the screen. If there is no response, insert the balance plug and plug it in. The electric display has a small button on the other end that is used to set the alarm voltage. When the voltage is lower than the set value, the buzzer will sound and the red LED will flash; the setting value is 3.3V. Press the button to change the voltage setting value and automatically save the user's current setting value. Note: When the voltage is below the set value, the buzzer will sound along with red LED light, pre-set value 3.3V.It also has a Push button control, which can change the voltage settings and save them.
