buzzer sound is good and is a useful for all those working on drone/quadcoptor's. i recommend this product very helpful
A low voltage alarm, known as the LiPo voltage tester, is utilized to obtain the voltage readings of a LiPo battery. The tester is connected to the balance plug of the battery and displays the voltage of each individual cell as well as the overall voltage of the battery pack.
Moreover, the LiPo voltage tester is equipped with an onboard alarm that emits a beeping sound when the battery voltage drops to a low level. This compact and lightweight alarm is specifically designed for use in DIY quadcopters and drones. By utilizing this alarm, one can prevent draining the LiPo battery completely.
