1. Introduction
The Diyeeni XT30 XT60 FPV Drone Smoke Stopper is a safety device designed to protect your FPV drone and its components from damage during initial power-on or after modifications. It acts as a resettable fuse, limiting current flow in case of a short circuit, indicated by an LED and an alarm buzzer. This device is compatible with 2-6S RC quadcopters and features both XT30 and XT60 connectors for versatile use.
2. Safety Information
- Important: Only one battery can be inserted into either the XT30 or XT60 input jack at a time. Do not connect batteries to both input jacks simultaneously.
- The product input voltage is 2-6S. Ensure your drone's components can withstand this voltage range.
- Do not attempt to fly or push the throttle with the smoke stopper connected, as it has a maximum output current limit of 1A. This device is for initial power-on testing only.
- Always inspect the smoke stopper for any visible damage before each use.
- Keep the device away from water and extreme temperatures.
- This device is not a substitute for proper wiring and component selection.

5. Setup
Follow these steps to properly connect the smoke stopper to your FPV drone:
- Identify Connectors: Determine whether your drone battery and drone power input use XT30 or XT60 connectors. The smoke stopper provides both options.
- Connect to Drone: Plug the appropriate output connector (XT30 or XT60) of the smoke stopper into your drone's power input port.
- Connect Battery: Plug your drone battery into the corresponding input connector (XT30 or XT60) on the smoke stopper. Ensure only one battery is connected at a time.
- Verify Connection: Double-check all connections to ensure they are secure and correctly oriented.

6. Operation
Once connected, the smoke stopper will monitor the current flow to your drone.
6.1 LED Indicator and Alarm Buzzer
- Normal Operation: When the drone is powered on and no short circuit is detected, the LED indicator will remain solid green. This indicates a safe power-on.
- Short Circuit Detected: If a short circuit or excessive current draw (above 1.2A trip current) is detected, the LED indicator will turn off, and the alarm buzzer will start beeping. This alerts you to an issue, preventing potential damage to your drone components.

6.2 Post-Detection
If the smoke stopper detects a short circuit:
- Immediately disconnect the battery from the smoke stopper.
- Inspect your drone's wiring and components for any visible shorts, incorrect connections, or damaged parts.
- Rectify any identified issues before attempting to power on again.
- Once the issue is resolved, reconnect the smoke stopper and battery to re-test. The smoke stopper will automatically reset once the short circuit condition is removed.
7. Maintenance
- Keep the smoke stopper clean and free from dust and debris.
- Store in a dry place at room temperature.
- Regularly check the connectors for wear or damage. Replace the device if connectors are loose or damaged.
- Do not attempt to open or modify the device, as this will void any potential warranty and may cause malfunction.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| LED off, Buzzer beeping immediately upon connection. | Short circuit detected in the drone or its components. | Disconnect battery. Inspect drone for shorts (e.g., solder bridges, exposed wires, faulty components). Correct the issue before re-testing. |
| No LED, no buzzer, no power to drone. |
|
|
| LED is green, but drone does not power on fully or behaves erratically. |
