ERS-CV01 - Precision Cell Voltage Sensor for compatible ExpressLRS ...
The 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.
As part of the ERS sensor family, the ERS-CV01 also supports pass-through expansion, allowing easy daisy-chaining with additional telemetry modules.
Package Includes:
1x ERS-CV01 Cell Voltage Sensor
3x Heat-Shrinkable Tube
1x Manual QR Code Card
Launch Video
Features
Real-Time Per-Cell Voltage Monitoring: Instantly view individual cell voltages through your radio for improved battery safety and performance.
Plug-and-Play Balance Port Connection:Easily connects to the battery’s balance port for accurate cell-level voltage readings.
Future-Ready Pass-Through:Includes an in-and-out port to daisy-chain additional ERS telemetry sensors as your setup grows.
Seamless ExpressLRS Integration:Designed to work effortlessly with compatible ER series ExpressLRS PWM receiver.
Plug and Play Compatible Receivers:
ER6 2.4GHz ExpressLRSPWM Receiver
ER8 2.4GHz ExpressLRSPWM Receiver
ER8G & ER8GV ExpressLRS PWM Receiver
Using Sensors with Non-Plug-and-Play PWM ExpressLRS Receivers:
Most PWM ExpressLRS receivers are fully compatible; those without a dedicated UART port require reconfiguration to support external sensors (e.g., for telemetry). To enable this, reassign two PWM output pins as a serial UART—one for TX and one for RX—via the receiver's Web UI (accessed by putting the receiver into WiFi mode) or via the ExpressLRS LUA script. This enables sensor connectivity while preserving the remaining PWM channels for servos or ESCs.
The ERS-CV01 Cell Voltage Sensor requires both the CellsValues LUA and the RadioMaster Sensor Configurator LUA to function correctly. Together, these LUAs enable per-cell voltage display, sensor configuration, and telemetry logging for post-flight review on EdgeTX radios.
After downloading, connect your radio to a Mac or PC inUSB-SD modeand copy the files as follows:
