Hydra Cobra 5 HV 12S 50,4V ESC 20A Peak BEC

Castle CC010-0183-00 - Hydra Cobra 5 HV 12S ESC

The Hydra Cobra 5 HV is a high-voltage marine electronic speed controller (ESC) tailored for 12S LiPo systems (50.4 V). It builds on the robust Cobra 5 HV architecture but adds water-cooling features and marine-grade protection, making it ideal for high-performance RC boats operating under extreme conditions.

Key Features

• Compatible with up to 12S LiPo (50.4 V) input

• 20A peak BEC with adjustable output (5.0–8.5 V in 0.1 V steps)

• Advanced 32-bit processing for smoother motor control and fast responsiveness

• Enhanced data logging: high sampling rate, long recording time, motor timing & acceleration data

• Water-jacket cooling integration for efficient thermal management in aquatic environments

• Rugged, waterproof build with CNC aluminum case and epoxy potting

• CRYO-DRIVE™ technology to reduce heat buildup under partial throttle

• On-the-fly tuning via auxiliary wire capability

• Firmware upgradeable and fully tunable via Castle Link software

Technical Specifications

• Dimensions: compact marine format (approximate to Hydra family)

• Weight: designed to balance performance and durability

• Motor connectors: high-current bullet interface

• Cooling interface: water jacket connections typical for marine systems

• Mounting: bottom-mounted holes

Applications & Usage

• Ideal for large RC boats requiring sustained power at high voltage

• Best matched with motors rated for high voltage (e.g. compatible with Hydra or Cobra series motors)

• Use connectors rated for 150+ A to handle current demands

• Rinse with fresh water after salt or dirty water exposure; remove fan or sensitive parts before full submersion

• Monitor ECU and motor temperatures via logs to prevent thermal issues
