This is a Fatshark Filtered Balance Lead Power Supply which is great if you want to have a nice clean power source for your FPV setup. In some cases your ESC/servos can cause interference with the video signal to cause poor quality video. Using a filtered balance lead helps to overcome this by filtering the power provided to the camera/ FPV transmitter for the best picture quality. This allows you to use a single battery for your FPV setup.
Not the cheapest?
Let us know, we will try to beat it!
