Hakrc 15A 4in1 FPV ESC

Reliable Power for Lightweight Builds

The HAKRC BLS 15A 4-in-1 ESC provides a steady 15A continuous current (20A peak) per motor, ideal for smaller FPV drones where weight and space are critical. It features an EMF8BB21F16G main control chip operating up to 48MHz, paired with imported MOSFETs and a new-generation three-in-one IC driver for dependable power delivery and longevity.

Efficient and Durable PCB Design

This ESC employs a high-end 4-layer PCB with 2-ounce copper thickness, reducing heat generation and improving efficiency. The PCB manufacturing process includes metallized edge wrapping on solder pads, preventing detachment during use or soldering, enhancing physical robustness and ease of assembly.

Smooth and Versatile Motor Control

Equipped with BLHeli_S firmware (G-H-15), the ESC offers stable performance and configurable parameters via BLHeliSuite software. It supports PWM, Oneshot125, Oneshot42, Multishot, and Dshot150/300/600 protocols. Combined with Damped Light, it ensures smooth throttle response, precise motor control, and efficient braking for an agile flight experience.
