7Semi XT60 + XT30 Smoke Stopper with Dual Resettable PPTC Protection for 1S–6S LiPo Systems
The 7Semi Amass XT60 + XT30 Smoke Stopper is a reusable circuit-protection and testing module designed for safely powering newly assembled FPV drones, RC models, robotics systems, and custom battery-powered electronics. Installed between a LiPo battery and the device under test, it limits excessive current caused by short circuits, wiring faults, and other abnormal conditions during initial power-up, helping reduce the risk of damage to ESCs, flight controllers, receivers, power-distribution boards, and connected electronics.
The module supports both XT60 and XT30 battery-system connections and operates from 3–30V DC, covering 1S–6S LiPo applications. Two resettable PPTC protection devices rated at 0.5A and 1.1A provide reusable overcurrent protection without requiring disposable fuse replacement after normal recovery. Integrated PWR and ERR LEDs provide quick visual indication of operating and fault conditions, while the compact 48 × 32 mm PCB is convenient for field testing, workbench diagnostics, and first-power-up checks.
Key Features
