About the Hydra Cobra 5 HV ESC
Powerful Marine Performance
The Castle Creations Hydra Cobra 5 HV 12S Brushless Marine ESC delivers uncompromising power for RC boats up to 50 inches, handling up to 12S LiPo (50.4V) with precision. Built on proven Cobra 5 architecture and re-engineered for water, it provides smooth motor control, rapid response, and bulletproof reliability for aggressive marine setups.
Advanced Cooling Protection
Featuring a machined water-cooled heatsink, dual anodized fittings, and a rugged CNC aluminum case potted in waterproof epoxy, the Hydra Cobra 5 HV ensures efficient heat transfer and total protection against the elements. CRYO-DRIVE technology minimizes heat generation during partial throttle operation, while upgraded current-sensing and thermal protection actively prevent failures.
Smart Tuning & Monitoring
Equipped with 32-bit processing, enhanced data logging, and onboard accelerometer measurements, this ESC provides detailed performance insights. Wireless setup is possible via B-Link2 Bluetooth and the Castle Link 2 app, while auxiliary wiring, audible alerts, and transmitter programming make on-the-fly adjustments easy. Firmware updates and tuning options are freely accessible, giving hobbyists complete control over their marine performance.

*Tech Note: Due to the high power nature of the Hydra Cobra 5 HV, you must use appropriately sized batteries and connectors. We recommend a minimum 150 amp connector for the Hydra Cobra 5; examples include Castle 6.5mm polarized, EC8, and QS8. DO NOT USE XT90, Traxxas, EC5/IC5, or any other connectors rated below 150 amps continuous.
