If you are running a single battery to power both your motors and FPV setup, you may notice interference in your video, seen as moving lines in your video feed. The interference is a product of the motors causing voltage fluctuations as they change RPM. If you find that you suffer interference when your motors are running and not when they aren’t, then the noisy power supply is probably your problem.
One solution is to use a dedicated battery to power your FPV setup, but this will add extra weight and it means yet another battery to charge. A better solution is to use what’s called a power filter (also known as an LC filter). The filter is installed between your FPV gear and the incoming power from the battery.
This particular L-C Power Filter 3A is vanishingly small in size, so you’ll have no problem finding space for it on even the tiniest of micro drones. The filter features a large inductor and capacitor components to remove noise, feeding clean power supply to your FPV gear. It’s rated at up to 3A of current and supports 1S – 6S LiPos.
- Built-in Reverse Polarity protection.
- Very low voltage drop.
- Compact and lightweight.
