Description
Speedhut 3-3/8″ EV 40-180F Motor Temp/Batt Level Gauge (FAE3-DG5-EV) is engineered to maximize your electric vehicle’s dashboard efficiency by integrating two essential monitoring functions into a single, compact 3-3/8″ (85mm) unit. Operating on a reliable CAN-Bus system at a 500K baud rate, this gauge provides precise, real-time readings of both your motor’s temperature (ranging from 40 to 180 degrees Fahrenheit) and your battery’s state of charge (from 0 to 100%). Early detection of potential issues is facilitated by integrated warning lights: one that illuminates when the motor temperature exceeds 160°F, and another that activates when the battery level drops below 15%. This dual functionality not only saves valuable dashboard space but also offers a comprehensive overview of your EV’s vital parameters, contributing to informed driving and proactive maintenance.
