RadioMaster ERS-CV01 Precision Cell Voltage Sensor for compatible ExpressLRS PWM Receivers

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.

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.
