LiPo 1-8S Battery Voltage Tester with Audible Alarm

This compact and reliable device is designed to test the electrical voltage to verify the status of Lithium Polymer (LiPo) batteries from a single cell to eight cells. The device detects and automatically displays the voltage of each cell individually, as well as the total battery voltage, making it ideal for remote control hobbyists, drone users, and battery maintenance.The device supports reverse polarity protection to prevent damage resulting from incorrect connections. A built-in alarm bell alerts the user when the voltage of any cell drops below a preset limit. The default low voltage warning value is set at 3.3 volts per cell, but this value can be customized with the press of a button for flexibility in various usage scenarios.

Main Features:

• Supports detection of LiPo battery voltage from 1S to 8S
