1S–8S LiPo Battery Voltage Tester & Dual-Speaker Low Voltage Buzzer Alarm

Description

The 1S–8S LiPo Battery Voltage Tester and Low Voltage Buzzer Alarm is an essential safety tool designed specifically to monitor, test, and protect multi-cell lithium battery packs. Featuring dual loud piezo speakers, this compact device alerts you immediately when individual cells reach a user-defined voltage threshold, preventing expensive battery damage or unexpected power loss during operation.

Equipped with a bright built-in LED display, the checker automatically cycles through the instant voltage of each individual cell one by one, concluding with the total aggregate pack voltage. By plugging your lithium balance lead directly into the header pins, you gain instant telemetry across 1S through 8S packs compatible with LiPo, LiFe, Li-Ion, and LiMn chemistries. You can easily customize the low-voltage alarm trigger anywhere between 2.7V and 3.8V per cell in 0.1V increments using the top-mounted mode setting button.

Note: Products shipped in static bag packaging may not include an outer retail sleeve. Always ensure correct balance plug pin orientation (negative pin aligned with the designated board marker) when connecting your battery pack.

Key Features

• 1S–8S Multi-Cell Compatibility: Works seamlessly with 1-series through 8-series Lithium Polymer, LiFe, Li-Ion, and LiMn battery packs.
• Loud Twin Piezo Buzzers: Dual integrated audio speakers deliver a clear, unmissable alarm when cells hit your pre-set low voltage threshold.
• Customizable Alarm Thresholds: Easily adjust the low-voltage warning trigger between 2.7V and 3.8V per cell in 0.1V increments using the onboard mode button.
• Sequential LED Telemetry: Automatically scrolls through individual cell voltages one-by-one followed by the aggregate total pack voltage.
• Compact & Lightweight Build: Pocket-sized footprint fits effortlessly into any field box, flight bag, or toolkit.
