Hobbywing Seaking V4 | HydroForce Pro 200A HV — High-Voltage Marine ESC with Active Cooling x2

The price is for 2x Hobbywing Seaking 200 V4

Engineered for relentless aquatic environments, the Hobbywing Seaking 200A HV V4 is a professional-grade marine electronic speed controller built to command motors demanding up to 200A of continuous current across a wide voltage range of 5S–12S LiPo. Whether you're pushing the limits of a competitive racing catamaran, controlling the thrust vector of an autonomous surface vessel (ASV), running a brushless trolling motor on a fishing kayak, or powering a drone boat in a hydrographic survey mission — this ESC is the silent, uncomplaining powerplant behind your operation.

The V4 upgrade brings a redesigned waterproof aluminium heatsink housing, improved active water-cooling intake compatibility, and a refined BEC output delivering stable 5V/5A for onboard electronics. The ultra-smooth throttle response curve — configurable via Hobbywing's LCD programme card or USB link — makes it equally at home in precision-control marine robotics as it is in full-throttle RC competition.

Built-in protections include over-temperature shutdown, low-voltage cut-off, signal-loss protection, and reverse polarity safeguards, making it a reliable backbone for mission-critical unmanned surface platforms, marine research payloads, and commercial bait-boat deployments.
