VIFLY ShortSaver V2 Smart Fuse

Brand: VIFLY. The VIFLY ShortSaver V2 is an intelligent electronic fuse designed to reliably protect RC builds from short circuits and component failure due to "magic smoke." Unlike traditional solutions such as an indicator bulb or a resettable fuse, the ShortSaver completely breaks the power circuit when a critical situation is detected, significantly reducing the risk of damage to the receiver, flight controller, video equipment, and other sensitive modules.

Key Advantages:

• Ultra-fast protection. The device disconnects power in 3 ms during a short circuit and reacts in 10 ms to overcurrent, protecting sensitive electronics from sudden damage.
• Selectable 1A/2A threshold. Support for two protection thresholds allows configuring the ShortSaver for small builds (1A) or more powerful configurations (2A), providing flexibility in use.
• Convenient ON/OFF switch. The presence of a switch simplifies receiver connection and power management without needing to hold a button and apply power simultaneously.
• Connector compatibility. The device is equipped with XT30 and XT60 connectors for both input and output, making it compatible with a wide range of batteries and RC model configurations.

Specifications:

• Dimensions (L x W x H): 42 x 30 x 10 mm.
• Connectors: XT30 and XT60 (input and output).
• Switchable current threshold: 1A / 2A.
• Response time: 3 ms (short circuit) / 10 ms (overcurrent).
• Input voltage: 7-25V (2-6S).

Operating Principle:

Unlike passive protection elements, the VIFLY ShortSaver uses an active electronic circuit-breaking mechanism: upon detecting a short circuit or wiring error, the device completely disconnects power, rather than merely limiting current. This approach avoids multiple damages, repeated restarts, and increases the chance of preserving expensive equipment in emergency situations.
