3a Transmitter – Product Description
- 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.
Features:
- Built-in Reverse Polarity protection.
- Very low voltage drop.
- Compact and lightweight.
Package Includes:
- 1 x L-C Power Filter 3A 1-6S Lipo for FPV Transmitter.
- 1 x Connecting wires.
L-C Power Filter 3A 1-6S Lipo for FPV Transmitter Overview
The L-C Power Filter 3A 1-6S Lipo is a compact noise-suppression module designed to clean up power supplied to FPV transmitters. It filters out voltage spikes and motor-induced interference when running a single battery for both motors and video gear, ensuring a stable, noise-free feed.
Key Features of L-C Power Filter 3A 1-6S Lipo for FPV Transmitter
- Supports 1S–6S LiPo inputs up to 26 V, handling common FPV battery packs
- 3 A continuous current rating to match micro and mini FPV transmitters
- LC network topology effectively reduces high-frequency noise from ESCs and motors
- Compact micro form factor for tight drone builds or lightweight rigs
- Simple two-wire in/out hookup—no additional components required
- Genuine FPV Micro LC-Filter supplied by Zbotic with fast shipping across India
Applications and Use Cases
- Clean power supply for analog FPV transmitters on racing and freestyle quads
- Noise filtering for fixed-wing FPV models using a shared battery source
- Power conditioning in compact cinewhoops and toothpick builds
- Stable supply for ground-station video transmitters or diversity receivers
- Integration into portable FPV backpack rigs for on-the-move filming
- Reducing video artifacts when running high-KV brushless motors
How to Use L-C Power Filter 3A 1-6S Lipo for FPV Transmitter
Connect the filter’s input leads directly to your LiPo battery (red to positive, black to negative) and route the output leads into your FPV transmitter’s power input. Secure the module in your frame, ensure all grounds share a common reference, then power on. The LC network immediately attenuates voltage spikes and motor noise, yielding a cleaner video feed.

Frequently Asked Questions
How does the L-C filter improve FPV video quality?
By using an inductor-capacitor network, the filter smooths out voltage fluctuations and blocks high-frequency interference generated by ESCs and motors, resulting in fewer video lines and a steadier image.
Can I use this filter with a 6S battery on a 3 A transmitter?
Yes. The FPV Micro LC-Filter 3A accepts up to 6S LiPo (26 V max) and delivers a clean 3 A output, ideal for most micro and mini analog transmitters.
What wiring precautions should I take during installation?
Ensure polarity is correct (red to positive, black to negative) and maintain a solid ground connection. Avoid routing exposed leads near high-current motor wires to minimize induction loops.
