2 in 1 power display/1-8S BB ringing low voltage alarm voltage display dual function buzzer

Product Introduction:
the voltage display for 1S ~ 8S Li battery detection, automatic detection of Li battery each cell voltage and total voltage. Support reversal connection protection.
It allows you to know the working status of your battery anytime and anywhere, so that the battery will not be damaged by over-discharge or over-charge.

Whether in flight or idle state, the electric display can be inserted into the battery balance charging connector to understand the battery power status.

No multimeter is more oh!

When the voltage is lower than the set value, the buzzer will sound and the red LED will flash. The set value is 3.3V, press the button to change the voltage set value and automatically save the current set value of the user.

Product parameters:

1. For 1S-8S Li battery detection

method of use:

turn the front of the display up (the side of the digital display), with the pin facing you, and insert the white balance charging plug of the battery along the pin on the left of the display. The display will sound BB twice immediately, and the screen will display the jumping number. If there is no response, just plug in the balance charging plug backwards. There is a small button at the other end of the display to set the alarm voltage of the display.
