With a lipo battery it is important that it never falls below a voltage level that is too low. This can cause permanent damage. This small device overcomes this.

The DragonPro® Lipo Voltage Tester & Low Voltage Buzzer constantly measures the remaining voltage of your lipo and indicates with a sound and red light when it is getting too low. This way you know immediately that it is time to recharge the lipo battery and you significantly reduce the risk of any damage.
