The problem it solves

What Is It?

The B2FPV Capacitor Cap is a tiny PCB accessory designed to simplify soldering onto capacitors — especially helpful in tight builds. It mounts on the top of most capacitors, eliminating the struggle of soldering capacitor legs directly to ESC pads.

Instead of fighting with stiff capacitor legs at awkward angles, you simply solder flexible wires to the convenient pads on the cap. The result is a much cleaner, more secure connection that holds up through the kind of impacts that would snap a traditional leg-soldered cap off your ESC.

Why it matters

Key Benefits

One of the biggest advantages of the B2FPV Capacitor Cap is durability. In a crash, capacitor legs soldered directly to the ESC can snap due to their stiffness. By using the Cap, you solder flexible wires instead — significantly reducing the risk of damage.

Cleaner, More Reliable Joints
No more messy capacitor legs or awkward solder angles. The PCB pads give you a proper surface to work with and a joint that actually looks good.
Faster Build Process
Spend less time fumbling with legs that don't want to cooperate and more time actually flying. The cap makes the whole process faster and less frustrating.
🔧
Flexible Mounting Options
Position your capacitor wherever it makes the most sense for your build — you're not locked in by leg length.
💪
Crash-Resistant Design
Flexible wire connections absorb impact instead of snapping. If you crash — and you will — your capacitor connection is far more likely to survive it.
Step by step

How To Use It

01
Mount the Cap
Press the B2FPV Capacitor Cap onto the top of your capacitor. It fits snugly over most standard caps used in FPV builds.
02
Solder Your Wires
Solder flexible wires to the PCB pads on the cap — positive and negative. Clean pads, clean joints. Way easier than trying to tack onto bare cap legs.
03
Connect to Your ESC
Run the flexible wires from the cap to your ESC or power leads. Position the cap wherever it fits best in your build.
04
Fly with Confidence
Your cap connection is now flexible and crash-resistant. No more coming home from a crash to find your cap ripped off the ESC.
