Hydra Cobra 5 HV 12S ESC (010-0183-00)
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
