Shark G2 30A Brushless ESC With Water Cooling 2-4S Compatible Built-In 5V/6V 4A BEC Waterproof Bidirectional Forward And Reverse Race-Ready For Twin-Screw Boats Catamarans Deep-V Hull RC Boats

G2 30A Water-Cooled Brushless ESC for Twin-Screw RC Boats
✔️ Bidirectional 30A ESC, 2-4S, single unit, built-in BEC

Designed for RC boating, this ESC powers twin-screw boats, catamarans, deep-V hulls, and underwater thrusters. It features waterproofing and an integrated water-cooling plate to keep temps in check during long, high-throttle sessions.

✅ 32-bit MCU with SR synchronous rectification for smooth startup and throttle linearity
✅ Waterproof internal PCB with marine-grade potting against splashes and humidity
✅ Built-in SBEC selectable 5V or 6V: 4A continuous on 20A/30A/40A/50A models, 8A continuous on 60A/80A/100A/120A models
✅ Bidirectional forward and reverse control for precise maneuvering
✅ Wide input ranges: 2-4S LiPo (20A-50A) or 2-6S LiPo (60A-120A)
✅ Protections including start-up, over-heat, low-voltage cutoff, phase-loss and signal-loss
