Review on 🔋 FrSky MLVSS Mini Lipo Voltage Sensor: Smart Port Enabled - OLED Screen NOT Required by Jason Sundstrom

Great little device. It's light enough that it doesn't affect my RC gyro, but it lets me know the battery voltage so I don't have to guess or use a timer. I'm just watching the voltage telemetry on my transmitter and everything is fine. It's much nicer than guessing or using a timer, especially when I have batteries of different capacities (mAh values). That way I can just use my transmitter to sound an alarm when the voltage is too low. I plan on buying a few more of these and customizing my other planes.
