The KONKER XT30/XT60 Smoke Stopper & Short Circuit Protector is the essential safety tool every FPV drone builder needs before first power-up. Whether you're wiring a 5-inch freestyle quad, a micro whoop, or a long-range fixed-wing RC aircraft, accidental solder bridges and short circuits can instantly destroy your ESCs, flight controller, or LiPo battery. The KONKER SCP stops that from ever happening — detecting faults in milliseconds and alerting you with a red LED and audible buzzer before any damage occurs.
The KONKER smoke stopper is designed for FPV builders and RC pilots at every experience level:
| Parameter | Value |
|---|---|
| Max input voltage | 30V (up to 6S LiPo) |
| Supported battery cells | 2S – 6S |
| Continuous current | 2.5A |
| Peak protection current | 3.5A |
| Connectors | XT60 + XT30 (one at a time) |
| Fault indication | Red LED + audible buzzer |
| Normal indication | Green LED |
| Display | Digital voltage readout |
| Housing | 3D-printed, compact form factor |
| Feature | KONKER SCP | Typical Smoke Stopper |
|---|---|---|
| Digital voltage display | ✅ Built-in | ❌ Not included |
| Dual XT30 + XT60 ports | ✅ Both on one unit | Usually XT60 only |
| Audible buzzer alarm | ✅ Yes | LED only on most |
| Storage case included | ✅ Yes | ❌ Usually no |
| 2–6S compatibility | ✅ Full range | Varies |
⚠️ CAUTION: This smoke stopper is designed for bench setup and testing only — not for in-flight use. Do not perform high-current motor runs through this device. Do not connect batteries to both the XT60 and XT30 ports simultaneously. Always remove the short circuit protector before flight.
A smoke stopper (also called a short circuit protector or SCP) is a safety device that sits between your LiPo battery and your FPV drone's electronics. When you power up a new build for the first time, any undetected solder bridge or wiring mistake will trigger the smoke stopper's protection circuit before current can reach and damage your ESCs, motors, or flight controller. The KONKER SCP uses a current-limiting circuit that trips at 3.5A and immediately alerts you with a red LED and buzzer.
Yes. The KONKER XT30/XT60 Short Circuit Protector supports 2S through 6S LiPo batteries (7.4V to 25.2V, max 30V input). It is compatible with the full voltage range used in modern FPV freestyle, racing, and cinematic quad builds.
The KONKER SCP includes both an XT30 input port (for smaller micro quads and whoop builds) and an XT60 input port (for 3-inch to 7-inch builds and most racing quads). You must use only one port at a time — never plug batteries into both ports simultaneously, as this could bypass the protection circuit.
No. The KONKER SCP is rated for continuous current at 2.5A, which is only sufficient for idle-speed motor direction checks and ESC configuration. It is a bench testing tool, not a flight component. Always remove it before arming your drone for flight.
A red LED (accompanied by the buzzer alarm) indicates that the protector has detected a short circuit or current overload in your wiring. Disconnect your battery immediately and inspect your build for solder bridges, incorrect polarity, or pinched wires before attempting to power up again.
