Radiomaster ERS-CV01 Cell Voltage Sensor

The RadioMaster ERS-CV01 Cell Voltage Sensor is a compact, plug-and-play telemetry module for use with compatible ExpressLRS receivers. Just connect the sensor to your battery’s balance port, and it will monitor the real-time voltage of each cell, transmit the data via the ExpressLRS receiver, and display it directly on your EdgeTX radio. Check out all of the Sensors and our entire RadioMaster selection at RaceDayQuads. Features Captures real-time individual cell voltages for improved battery safety and performance Easily connects to the battery’s balance port for accurate cell-level voltage readings Supports daisy-chain expansion for additional ERS telemetry sensors as your setup grows Seamless ExpressLRS integration Compact & Lightweight SENSOR CONFIGURATION & TELEMETRY LOGGING To configure this sensor and view telemetry on your EdgeTX radio, install the RadioMaster Sensor Configurator LUA. The LUA allows adjustment of sensor settings, enables proper telemetry display, and supports data logging for post-flight review.
