EMAX Nano Series 12A ESC V2 with Active Braking (3S-4S)

The EMAX Nano Series 12A V2 is a single brushless ESC for small multirotors running 3S or 4S LiPo. It handles 12 A continuously with short bursts to 15 A, and version 2 adds active braking for a quicker response to throttle changes.

Key features

• Active braking: drives the motor down when throttle drops instead of letting it coast, so prop speed changes faster.
• OneShot125 support: a faster throttle signal than standard PWM for quicker flight-controller-to-ESC updates.
• Twisted-pair signal wire: reduces noise pickup on the throttle line.
• No BEC: power the receiver and flight controller from a separate BEC or the PDB's regulator.

Specifications

• Continuous current: 12 A
• Burst current: 15 A
• Input: 3S–4S LiPo (11.1–14.8 V nominal)
• BEC: None
• Throttle signal: PWM, OneShot125

Choose motors whose peak draw on your prop and voltage stays below 12 A; a quadcopter needs four of these ESCs.
