Lipo Battery Voltage Tester Meter & Low Voltage Buzzer Alarm 1-8S Lipo Li-ion LiFe LiMn Battery Checker Battery Monitor with LED & Buzzer Alert Prevent Overcharge & Overdischarge RC Drone FPV Car Boat Airplane Battery Voltage Display & Pro

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.

Specifications:

- Battery Compatibility: 1S-8S Lipo, Li-ion, LiFe, LiM

- Voltage Detection Precision: 0.01V

- Unit Voltage Display Range: 0.5V-4.5V

- Total Voltage Display Range: 0.5V-36V

- 1S Test Mode Voltage Range: 3.7V-30V

- Low Voltage Alarm Mode: 2S-8S

- Alarm Set Value Range: OFF-2.7V-3.8V

- Size:4 x 2.5 x 1.1 cm

- Weight: 9g

How It Works:

1. Connect the battery to the tester.

2. Voltage will be displayed in sequence for each cell and total voltage.

3. If any cell voltage drops below the set alarm value, the buzzer will sound and the red LED will flash

4. The alarm will automatically stop when the voltage is restored or the battery is unplugged.

Package Includes:

✔ 1 x Lipo Battery Voltage Tester & Low Voltage Alarm

ideal for RC drones, FPV racing, RC cars, boats, airplanes, and any device using Lipo batteries. Ensure your battery’s health and avoid damage with this must-have tool!
