30A Brushless ESC 2-3S with 5V BEC (No Connectors)

A standard 30A brushless ESC for 2–3S multirotors and RC planes, the usual partner for A2212 motors in the 1000–2200KV range on DIY quadcopters. It ships with bare wire leads, so you solder on the motor bullets and battery plug that match your build.

Key features

• 30A continuous, 40A burst for under 10 seconds
• Runs on 2–3S LiPo or 4–10 cell NiMH, with automatic cell detection
• Built-in 5 V BEC to power the flight controller or receiver
• Low-voltage protection: slows down at 3.0 V/cell, cuts off at 2.9 V/cell
• Brake on/off setting
• 23 g in a 45 × 24 × 9 mm package

Calibrate the throttle range on all ESCs through your flight controller before the first flight. On a multirotor, land on the flight controller's battery warning well before the ESC's 2.9 V/cell cut-off — an ESC cutting power mid-air brings the drone down. The case colour may vary.
