Model:VB-LA-23S

Specification：

This device can be used as a battery tester, or installed in your electric plane and used as a 2-3S Li-Po alarm. It features two rows of LEDs, one green, the other red, and an extremely loud piezo buzzer.

A fully charged 2S Li-Po will indicate with two green LEDS, a 3S will show three green LEDs. As the voltage drops, the red LEDs will come on, and once the voltage drops below 3 volts per cell, the piezo buzzer will begin to sound.
