XB100 1–8S Battery Voltage Alarm & Power Display — Dual Function Buzzer

Keep your RC vehicle, drone, or DIY electronics project running safely with the XB100 1–8S Low Voltage Alarm Buzzer. This compact dual-function module simultaneously displays real-time cell voltage on its bright LED screen and triggers a loud audible buzzer the moment your battery pack dips below a preset threshold — giving you instant, at-a-glance awareness before your pack ever over-discharges.

Compatible with 1S through 8S LiPo, LiFe, and LiIon battery packs, the XB100 is an essential monitoring tool for hobbyists, RC enthusiasts, and electronics makers alike. Available in 2 color options to match your build or personal style.

Frequently Asked Questions

Q: What battery types and cell counts does the XB100 voltage alarm support?

A: The XB100 is compatible with LiPo, LiFe, and LiIon battery packs ranging from 1S (1 cell) up to 8S (8 cells), making it a versatile choice for a wide range of RC and electronics projects.

Q: How does the dual-function buzzer work?

A: The XB100 simultaneously shows real-time voltage on its LED display and sounds a loud buzzer alert when battery voltage falls below your preset threshold — so you get both a visual readout and an audible warning without needing two separate devices.

Q: Do I need to solder anything to install the XB100?

A: No soldering is required. The XB100 connects directly to the standard JST-XH balance connector already present on most LiPo and LiFe battery packs, making setup quick and tool-free.
