Ultra Precision LiPo Voltage Checker w/ Adjustable Voltage Level Warning Buzzer

OVERVIEW
Our LiPo Battery Voltage Tester And Low Voltage Buzzer Alarm is a simple, compact, 2-in-1 device that is perfect for your 1-8S batteries. Just plug in your battery’s balance connector and you’ll know the pack voltage (both total pack and individual cell) instantly. The built-in low voltage alarm monitors the pack voltage and will automatically emit a buzzer sound and blink an LED light when the voltage drops below the threshold (you can easily adjust the low voltage threshold by pressing the small button on the unit.)
