Alex Drive 20A 3-6S Brushless ESC

The Alex Drive 20A is an Indian-made single brushless ESC for drone and RC builds, rated for 3S to 6S LiPo packs. Each unit drives one motor, so a quadcopter needs four; choose it for mid-size multirotors whose motors stay comfortably below 20 A at full throttle. Available in V1 and V2 versions.

Key features

• 20 A continuous current rating for stable, reliable output
• Accepts 3S to 6S LiPo (11.1–22.2 V nominal) for flexibility across platforms
• Built-in LED indicators for real-time status feedback
• Smooth, responsive throttle control for steady flight
• Designed and built in India

Specifications

Size the ESC to your motor: check the maximum current on the motor's thrust table for your prop and battery, and keep it below 20 A with some headroom. Both versions carry the same 20 A, 3–6S rating.
