This is the Traxxas Auto-Detectable Smart Voltage Sensor.
The auto-detectable voltage sensor plugs into the optional TQi Telemetry Expander to provide real-time voltage data while you drive. Real-time telemetry requires a TQi radio with Traxxas Link Wireless Module and the free Traxxas Link app for your mobile device.
