VIFLY ShortSaver2 (ShortSaver V2) Electronic Fuse — Smart Smoke Stopper

Product summary: The VIFLY ShortSaver2 (ShortSaver V2 Smart Smoke Stopper) electronic fuse is a compact and fast-acting protection module for drones and other electronic assemblies, compatible with 2–6S (7–25V) LiPo batteries. The original description specifies the VIFLY brand, while the parameters also list SMO as the manufacturer/brand.

Device purpose

The ShortSaver V2 is designed for reliable power protection against short circuits and overcurrents: the device uses an electronic power cut-off mechanism that completely stops current flow when a dangerous situation is detected, preventing damage to other components, smoke, and fire.

Key advantages and features

• Short-circuit prevention: complete current flow cut-off upon detection of a short circuit or wiring error.
• Reaction speed: cut-off when consumption exceeds 1A or 2A within 3 ms for short circuits; for overcurrents, the cut-off time is 10 ms.
• On/off switch: built-in switch for convenient connection and binding of the receiver and other modules.
• Current threshold selector: ability to select a 1A or 2A threshold to adapt to different electronic assemblies and load power.
• Universal connectors: equipped with Amass XT60 and XT30 (XT30 and XT60 input/output), ensuring compatibility with popular battery connectors and facilitating integration into existing systems.

Technical specifications

• Dimensions (L x W x H): 42 x 30 x 10 mm
• Connectors: XT30 and XT60 (input and output), also specified as Amass XT60 and XT30
• Switchable current threshold: 1A / 2A
• Cut-off time: 3 ms (for short circuit) / 10 ms (for overcurrent)
• Input voltage: 7–25 V (2–6S)

Package contents

• 1 x VIFLY ShortSaver V2 Smart Smoke Stopper Electronic Fuse

Brand / manufacturer: The original description specifies the VIFLY brand. The product parameters also include the name SMO.

The ShortSaver V2 is an ideal solution for those seeking compact, lightweight, and reliable electronic protection for aircraft. The device easily integrates into the power line thanks to XT30/XT60 (Amass) connectors, features a switch for convenient operation, and allows adjustment of the trigger threshold depending on the load power. Fast cut-off within 3 ms for short circuits significantly reduces the risks of thermal damage and component failure, while the 10 ms time for overcurrent provides additional protection during prolonged current peaks.

The device is suitable for professional pilots, FPV enthusiasts, and anyone building or servicing unmanned systems that require reliable and fast power protection. Thanks to its compact dimensions of 42x30x10 mm, it can be easily placed in the drone chassis or in the power link controller's mounting assembly. Additional advantages: quick connection to existing batteries thanks to Amass XT connectors, easy current threshold switching during diagnostics and service, guaranteed compatibility with 2–6S batteries (7–25V), and convenient integration into various designs.

If you are looking for a reliable Smart Smoke Stopper to protect your components from short circuits and overloads, the VIFLY ShortSaver V2 combines high reaction speed, universal XT30/XT60 connectors, and the ability to select a 1A/2A current threshold, making it a versatile solution for many drone projects and models.
