The first time you power your drone is often called the "smoke test". If everything powers up fine, you've passed; if not, you'll be inhaling blue magic smoke and replacing parts! Not with the TBS Smoke Stopper! Compared to standard smoke stoppers, the TBS Smoke Stopper offers much lower trip and hold currents, as well as faster reaction time. We also provide a wider variety of input voltages and in- & output connectors than any other smoke stopper!
Specifications
● Connector: XT30 & XT60 (input and output)
● Input voltage: 1-14S (3 - 60V)
● Trip current: 1.0A
● Hold current: 0.5A
Disclaimer: This is just a fuse. Something may still break by the time the fuse trips. It won't protect against all kinds of damages, but it's still way better than nothing at all!

Reliable protection when working on FPV drones. The reset feature is a big advantage and it supports all the battery voltages I use regularly.

Small enough to carry everywhere and simple enough that even new pilots can use it confidently. A cheap insurance policy for expensive electronics.

Build quality is excellent and the resettable fuse is much more convenient than older bulb-style smoke stoppers. Makes troubleshooting much easier.

Every beginner should own one of these. I accidentally reversed a connection on my first build and the smoke stopper prevented what would have been an expensive mistake.

One of those tools you hope you never need but are glad to have. Works exactly as advertised and gives me peace of mind whenever I finish a new build.

Great little safety device. The XT30 and XT60 compatibility makes it convenient since I fly different sizes of quads. Easy to keep in my field bag.

I wasn't sure if I needed one until it caught a short on a newly installed ESC. That single incident saved me far more money than the cost of this tool.

Simple, compact, and reliable. I tested it on a fresh 6S build and it immediately caught a wiring issue before any damage was done. Paid for itself in one use.

FAQFeel free to ask us any questions
Q: What is TBS Smoke Stopper and why do I need it?
A: TBS Smoke Stopper is an essential safety tool for FPV drone builders. It works as a resettable fuse between your LiPo battery and drone, helping detect short circuits and reducing the risk of damaging expensive electronics during the first power-up.
Q: When should I use the TBS Smoke Stopper?
A: You should use it whenever you power on an FPV drone for the first time, especially after building a new quad, replacing components, repairing crash damage, or making wiring changes. It helps identify potential issues before they become costly failures.
Q: Will the TBS Smoke Stopper completely protect my FPV drone?
A: While no device can guarantee complete protection, the TBS Smoke Stopper significantly reduces the risk of damaging your flight controller, ESC, VTX, and other electronics by limiting current flow when a short circuit is detected.
Q: Is the TBS Smoke Stopper reusable?
A: Yes. It features a resettable self-healing fuse design. If protection is triggered, simply disconnect the power, fix the issue, and reset the device for continued use without replacing any components.
Q: What battery voltage does the TBS Smoke Stopper support?
A: The TBS Smoke Stopper supports a wide voltage range from 1S to 14S LiPo batteries (3V–60V), making it compatible with most FPV drones, RC aircraft, and other battery-powered projects.
