Description
The BX100 1S–8S Battery Voltage Tester and Low Voltage Buzzer Alarm is an essential, high-visibility safety accessory designed for RC pilots, drone operators, and lithium battery users. Featuring loud twin piezo speakers, this compact unit alerts you immediately when your individual cells drop to a user-defined threshold, protecting your expensive battery packs from irreversible over-discharge damage during operation.
Equipped with a bright built-in LED display, the BX100 automatically cycles through individual cell voltages one by one before concluding with the total pack voltage. By simply plugging your lithium balance lead into the header pins, you gain instant, precise 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 from 2.7V to 3.8V per cell in 0.1V increments using the top-mounted setting button.
Note: Product may come in a white or protective housing variant (with BBX1-8S labeling, function remains identical). Always ensure correct balance plug pin alignment (negative pin to the designated marker) when connecting your battery.
Key Features
- 1S–8S Multi-Cell Compatibility: Works seamlessly with 1S through 8S Lithium Polymer, LiFe, Li-Ion, and LiMn battery packs.
- Loud Twin Piezo Buzzers: Dual integrated speakers deliver an unmissable acoustic alert when cells hit your pre-set low voltage limit.
- Customizable Alarm Thresholds: Easily adjust the low-voltage warning trigger between 2.7V and 3.8V per cell in 0.1V increments via the onboard mode button.
- Sequential LED Telemetry: Automatically scrolls through individual cell voltages one-by-one followed by the aggregate total pack voltage.
- Enclosed Protective Design: Features a durable protective case housing to safeguard the delicate internal circuitry during field use.
Benefits
- Prevent Battery Destruction: Stop puffed packs and dead cells by catching low-voltage states before your battery suffers permanent damage.
- In-Flight / On-Board Safety: Lightweight enough to mount directly on RC models or keep in your field box for quick pre-flight checks.
- Absolute Peace of Mind: Inexpensive insurance to protect high-end lithium batteries from over-discharge during heavy loads.
- Plug-and-Play Simplicity: No external power required—simply plug directly into the standard multi-pin balance connector.
Applications
- RC Drones & Airplanes: Onboard low-voltage warning alarm or rapid pre-flight cell balance checking for multirotors and fixed-wing craft.
- RC Cars & Boats: Quick voltage auditing and low-voltage protection monitoring for high-discharge surface vehicles.
- Workbench & Battery Storage: Rapidly auditing loose lithium packs in your workshop or storage bags.
- Portable Energy Packs: Monitoring multi-cell custom 1S–8S lithium power banks and field equipment.
