Cell Spy Alarm Voltage tester

Cell Spy Alarm - 8S Audio Voltage Tester

Test your lipo's voltage and protect it from over-discharging with this one simple tool!

This Cell Spy Alarm doubles as both a voltage tester and a low-voltage buzzer in one compact, easy-to-use package! The digital readout displays individual cell voltages for up to 8 cells as well as your battery's total voltage. The Cell Spy Alarm can also read the cell voltage of 1S batteries with Ultra Micro connectors. Best of all, the Cell Spy Alarm doubles as an onboard low-voltage buzzer to protect your lipos from being over-discharged during use. Just set the alarm to the minimum voltage you're comfortable with (between 2.7 and 3.8 volts) and the buzzer will sound when your cells have been discharged to the limit you've selected.
