ReadyToSky XT60 Smoke Stopper Plug, Short-Circuit Protection

An XT60 smoke stopper plug for the first power-up of a new or repaired build. Plugged in-line between the battery and the model, it limits current if there is a short circuit or wiring fault, so you get a warning instead of a burnt ESC or flight controller. It suits FPV quads, fixed-wing models, RC cars and boats that run XT60 batteries.

Key features

• Resettable PPTC fuses limit fault current and recover automatically once the fault is removed — nothing to replace after a trip
• Reverse-polarity protection stops power flowing if the battery is connected the wrong way round
• Visual fault indication flags a problem before you connect the battery directly
• XT60 connectors at both ends, so it fits in-line without soldering

Use it for the initial plug-in, configuration and bench checks only. It is designed to restrict current, so remove it before arming or spinning up motors under load.
