JR Propo Flight Pack Voltage

This is the sensor which correspond with telemetry display of “F-Pack V” to measure total voltage
It is to measure the voltage difference, there is no polarity requirement for the sensor lead?

· The sensor can be used to measure total voltage of the battery , or the voltage on the single cell on battery.
· The LED indicates voltage measurement is taking place.
* The sensor wire must be soldered to the battery leads or terminals.

• Detection range : DC 0.0 - 100.0V
• Operating Voltage : 4.0V-8.5V
