4IN1 ESC 45A 60A Four‑in‑One Electronic Speed Controller BLHeli‑S Brushless Motor Driver For FPV Racing Drone Quadcopter

4‑in‑1 BLHeli‑S ESC 45A / 60A Four‑in‑One Electronic Speed Controller

📌 Product Overview This 4‑in‑1 BLHeli‑S ESC integrates four independent drive circuits on a single PCB, specially designed for FPV racing drone builds. It supports 2‑6S Li‑Po battery input and runs BLHeli‑S firmware (BLS J_H_30_REV16_7). Two current options are available: 45A continuous (55A burst for 5 seconds) and 60A continuous (70A burst for 5 seconds). The compact 41×41mm board adopts a 30.5×30.5mm standard mounting hole layout, compatible with common FPV frame shock‑absorbing mounting structures. On‑board filter capacitors suppress back‑EMF interference, stabilize power voltage and protect flight controller and ESC core components. Lightweight at only 11g, it delivers fast motor response, low heat generation and reliable dynamic performance for freestyle and racing quadcopters. ✨ Core Features

📐 Dimension Info PCB size: 41mm × 41mm；Mounting hole spacing: standard 30.5mm × 30.5mm；Net weight: 11g, lightweight to reduce drone take‑off weight. ⚠ Important Usage Notice

1. Match the ESC current rating with motor and battery load to avoid long‑time over‑current operation.
2. Strictly follow the wiring diagram for power supply (BAT+/BAT‑) and four‑motor signal wiring (M1‑M4).
3. Use 2‑6S Li‑Po battery only, do not exceed the maximum voltage range.
4. Ensure sufficient airflow cooling under heavy‑load racing flight to prevent overheating damage.
5. Check solder joints for short circuit before power‑on test.

🛠 Application Scenarios FPV racing quadcopter, freestyle drone, multi‑rotor DIY assembly, RC model aircraft, small‑size brushless power system modification.
