ViFly ShortSaver 2 Smart Smoke Stopper (XT60 + XT30)

The VIFLY ShortSaver 2 is an electronic smoke stopper designed to protect your FPV builds from wiring shorts during initial power-up. Unlike traditional polyfuse designs that rely on heat to break the circuit, this solid-state stopper completely severs the power connection in under 3 milliseconds, preventing permanent component damage to your flight controller, ESC, or video transmitter.

Key features

• Solid-state electronic cutoff triggers in under 3ms, offering significantly faster protection than standard PPTC fuses.
• Integrated power toggle button lets you connect the LiPo first and switch on the quad when ready, simplifying receiver binding and firmware flashing.
• Selectable 1A and 2A current thresholds accommodate both low-power whoops and heavier 5-inch or 7-inch stacks.
• Features genuine Amass XT30 and XT60 connectors on both input and output sides for broad battery and build compatibility.

Specifications

• Input voltage: 2-6S (7.4V - 25.2V)
• Connectors: Amass XT30 and XT60 (Input and Output)
• Trip thresholds: 1A and 2A (selectable via button)
• Trip time: < 3ms

Connect the ShortSaver 2 strictly for bench testing and configuration. Never attempt to arm motors or fly while the device is inline, as motor startup current spikes will immediately trip the breaker and cut power.
