Electronic Speed Controller ESC KALUSH v1 12S/80A

Electronic Speed Controller ESC KALUSH v1 12S/80A from the brand 603700 FPV — is a top-tier ESC designed for large and high-speed FPV drones with 13"+ frames and 12S architecture. Its dual-board design, premium components, and optimized board topology ensure reliable and predictable operation even under extreme loads.

Purpose and Compatibility

This controller is built for heavy and powerful drones where stable motor power, thermal conductivity, and current overhead are critical. Recommended for quadcopters with a frame of 13" or larger and LiIon/LiPo batteries up to 12S. Product category: 

Key Advantages

Top-Tier Components

Hi-End Vishay (USA) 602A/60V/0.85 mOhm MOSFETs ensure minimal heat loss and high operational efficiency under load.

Dual-Board Architecture

The power and signal sections are separated onto individual boards. This topology allows the controller to confidently handle extreme loads without signal quality degradation.

12 OZ Copper

A six-layer board with 2 OZ copper per layer provides the necessary current carrying capacity and effective heat dissipation during prolonged aggressive flights.

Convenient Power Section Soldering

When using two 6S batteries, external jumpers are not required, simplifying assembly and reducing potential points of failure.

Original Rubicon Included

Includes two low ESR Rubicon 2200 uF / 63 V / 0.015 mOhm filter capacitors, which smooth out current peaks during rapid accelerations.

Compact Size

The minimal dimensions for this ESC class (57×64 mm) allow for easy integration into popular frame solutions.
