Protect Your Batteries & Ensure Safe Operation with This Lipo Voltage Tester & Buzzer Alarm!

This Lipo Battery Voltage Tester & Low Voltage Alarm is an essential tool for monitoring battery health, preventing over-discharge, and ensuring safe operation of RC vehicles, drones, airplanes, boats, and other electronic devices. Designed for 1S-8S Lipo, Li-ion, LiFe, and LiMn batteries, this compact and lightweight tester provides precise voltage readings while also alerting you with a buzzer alarm and red LED light when voltage drops below the preset level.

Key Features & Highlights:

Wide Compatibility– Supports 1-8S Lipo, Li-ion, LiFe, LiMn batteries.

Voltage Display Function– Accurately measures battery voltage to prevent overcharging & over-discharging.

Low Voltage Alarm Function– Buzzer and red LED alert for low battery levels.

Adjustable Alarm Threshold– Alarm can be set between 2.7V-3.8V per cell (default 3.3V).

Reverse Connection Protection– Automatically prevents damage if connected incorrectly.

Compact & Lightweight – Only 9g, making it easy to carry and install in small RC models.
