FrSky Battery Voltage Sensor - FrSky Telemetry System

Steps the voltage from your 3s or 4s battery pack down to a safe voltage for your FrSky telemetry enabled receiver to read.
Availability: In stock
£2.47

Overview:

This is one of a range of sensors designed and developed by FrSKY to collect important flight information and performance data which can then be transmitted via a telemetry-enabled receiver to a telemetry-compatible transmitter module where it can be displayed on an LCD screen.

This particular sensor is used to read the voltage of an external battery eg. LiPo flight battery, video or other accessory battery. It is connected directly to the external analog telemetry port (A2) provided on FrSKY telemetry enabled two-way 'D' series receivers where the data can be sent to a compatible transmitter module such as the all-in-one FrSKY ACCST 2.4GHz DHT-U module with integrated telemetry and in-built display with audio alarms.

The FBVS-01 sensor is supplied pre-wired to pin 3S on the circuit board for monitoring LiPo batteries up to 5S in the range: 0V~19.8V.  If you intend to use batteries only up to 3S, you can get get more accurate voltage metering by simply re-soldering the red wire to pin 2S. 

 

Features:

- Three voltage ranges: 0V~6.6V (1S), 0V~13.2V (up to 3S), 0V~19.8V (up to 5S).
- The battery voltage division ratio for each option is 2:1 (1S), 4:1 (up to 3S), 6:1 (up to 5S).

 

Specifications:

- Lead length: 265mm (overall)
- Dimensions: 10 x 20 x 2mm (sensor)
- Weight: 2g 

 

Note: If you are using only one battery in your model without a separate receiver battery i.e. you are using the ESC BEC, you should NOT connect the black (GND) wire of the voltage sensor because GND is already supplied to the receiver from the ESC. Connecting another ground is likely to cause a ground loop that could result in premature failure of attached electronic components.

Alternatively, If you are using a separate battery for the receiver/servos and the FBVS-01 is being used to monitor your LiPo flight pack, both the red and black wires may be connected to the flight pack.
