GEPRC Smoke Stopper (XT30/XT60, 1-6S)

The GEPRC Smoke Stopper is a resettable inline fuse for the first power-up of a new or repaired quad. Plug it between the LiPo and the drone: if the wiring is sound the LED stays lit, and if there is a short it cuts power within milliseconds, before a solder bridge or reversed lead can burn out the FC, ESC or VTX.

Key features

• XT30 and XT60 on both input and output, so one tool covers micro and 5-inch-class builds
• Works from 1S to 6S LiPo (3-30 V)
• Trips in 3 ms on a short circuit and 10 ms on over-current
• 1.0 A trip and 0.5 A hold current: enough to boot the electronics, low enough to catch a fault
• Resets itself after a trip, so it is reusable
• LED status: lit means normal, dark means a short was detected

Specifications

• Input voltage: 1-6S LiPo (3-30 V)
• Connectors: XT30 and XT60 (input and output)
• Trip current: 1.0 A
• Hold current: 0.5 A
• Trip time: 3 ms (short circuit) / 10 ms (over-current)
• Dimensions: 58 x 35 x 10.1 mm
• Weight: 13.6 g

Use it on the bench only: with a 0.5 A hold current it cannot stay in line while motors spin, so remove it before arming or flying. A fuse limits damage rather than guaranteeing none, so still check polarity and look for solder bridges before the first plug-in.
