The Lipo Alarm is designed to help prevent your lithium polymer batteries from being over-discharged during use. When lipo batteries are discharged to less than 3.0V-per-cell, they can be permanently damaged and even potentially dangerous. The Lipo Alarm uses both a 95dB buzzer and bright red LEDs to warn you when your battery's voltage is getting too low and it's time to recharge. If the battery is discharged to 3.15V-per-cell or less, the red LEDs will light up and the buzzer will sound.
