BX100 1-8S Lipo Battery Voltage Tester

1S–8S Multi-Cell Voltage Testing: Designed to monitor and test individual cell voltages and total pack voltage for 1 to 8-series (1 S - 8 S) LiPo, Li-ion, LiMn, and LiFe battery packs.

Dual Loud Acoustic Alarm (100 dB): Equipped with twin piezo buzzer speakers that emit a high-decibel alarm when any connected cell drops below your configured voltage threshold.

Adjustable Low-Voltage Threshold: Features a tactile top push-button allowing users to customize the low-voltage alarm trigger setting from 2.7V to 3.8V per cell (or turn the alarm OFF).

3-Digit Bright Red LED Display: Cycles automatically through total pack voltage, individual cell voltages (Cell 1 to Cell 8), and real-time status readouts.

Plug-and-Play Balance Port Connector: Standard 0.1" (2.54 mm) header pins plug directly into 1S–8S battery balance leads without needing external power.

Housing Material: Protective black plastic casing with built-in acoustic sound vents and gold-plated pin headers.

Technical Specifications:

Voltage Detection Precision: -+ 0.01 V.

Cell Voltage Display Range: 0.5 V – 4.5 V.

Total Pack Voltage Display Range: 0.5 V – 36V.

Alarm Set Points: OFF, 2.7V – 3.8V per cell.

Color: Black Shell.

Usage Advice: Insert the negative (black ground wire) of your battery’s balance connector into the pin marked - or GND on the tester to power up and begin cell scanning.

Maintenance: Keep header pins clean and free of solder residue, dust, or moisture to prevent short circuits and preserve accuracy.

Essential Onboard Flight Guard: Position as an indispensable safety module for RC drones, quadcopters, aircraft, and RC vehicles to prevent over-discharging expensive LiPo batteries during flight.

Highlight Dual Speaker Loudness: Emphasize how the ultra-loud 100 dB alarm can be easily heard over roaring brushless motors and distance, giving pilots plenty of time to land safely.

Recommended Cross-Sell Add-ons: Pair with LCD Digital Battery Capacity Checker CellMeter 1-8S, 150A High Precision WATT Meter & Power Analyzer Module, and ESD antistatic mat 50x40CM PCB Welding Mat.
