Radiomaster ERS-CV01 Cell Volt Sensor

Overview:
The RadioMaster ERS-CV01 is a dedicated cell voltage telemetry sensor designed for use with compatible ExpressLRS PWM receiver systems. It connects directly to a battery’s balance port and measures the voltage of each cell in real time. This data is transmitted via the CRSF protocol to a supported radio running EdgeTX, providing per-cell voltage visibility that aids in battery safety monitoring and power management. The ERS-CV01 also supports pass-through expansion, allowing additional ERS sensors to be daisy-chained in larger telemetry setups.

The ERS-CV01 is suited to pilots and model builders who want detailed insight into individual cell voltages during flight or operation.

Features:
- Provides real-time per-cell battery voltage monitoring for accurate telemetry feedback.
- Connects directly to the battery balance port for straightforward installation.
- Integrates seamlessly with compatible ExpressLRS PWM receivers for telemetry transmission.
- Includes pass-through ports to allow chaining of additional ERS sensors without rewiring.
- Compact and lightweight design minimises space and weight impact on models.
