XTBengineering Labs Solid State Smoke Stopper. 

I've always wanted something that was a little smaller, neater, and less fragile than an automotive light bulb to keep in my field bag. Couldn't find anything on the market. These are great for testing a new build, reprogramming ESCs, or doing fail-safe checks with the props on.

The Solid State Smoke Stopper uses a Resettable fuse (PPTC). Connectors are high quality Amass XT60's & XT30's.

Specifications:

XT60/XT30
1-5s capable (24v Max)
1.1A Hold Current, 2.2A Trip Current
0.5S Trip time

How to Use:

Plug the Solid State Smoke Stopper in the battery first, then plug into the device you wish to test.

Green led on, OK.
Green led dim, Fuse tripped.
Green led off, Shorted.
To reset the Solid State Smoke Stopper, unplug for 10 seconds.

Note: Solid State Smoke Stopper / Light Bulbs / Fuses / Circuit breakers are not 100% foolproof way of keeping the magic smoke in. It’s always best to use in conjunction with a multimeter.
