ZTW Shark G2 20A 32-Bit Waterproof ESC 2-4S with Water Cooling and SBEC for RC Boats and Light Underwater Thrusters
32-Bit Processing for Smooth, Precise Control
At the heart of the Shark G2 20A is a high-performance 32-bit microprocessor with an improved algorithm, delivering faster response, super smooth start-up, and highly accurate throttle linearity. Ideal for small sport RC boats, scale vessels, and lightweight underwater thrusters demanding precise control.
20A Continuous / 30A Burst on 2-4S
Built with new-generation MOSFETs that generate low heat and withstand instant current surges, this ESC delivers 20A sustained and 30A peak on 2-4S LiPo — the most common battery range for compact recreational boats and small subsea propulsion systems.
Splash-Proof with Flat Water Cooling
The ESC is waterproof-glued for splash protection, combined with an integrated flat water-cooling design that ensures excellent heat dissipation in the tight motor boxes of small boats and compact underwater enclosures.
4A Adjustable SBEC
A built-in 5.0/6.0V switching BEC supplies 4A continuous, powering the receiver and standard servos directly — no external BEC needed for typical small boat setups.
Synchronous Rectification for Efficiency
Synchronous rectification significantly reduces ESC heating, improving driving efficiency and saving battery energy — extending run time for both recreational boating and lightweight underwater missions.
Forward/Reverse & Separate Board Design
Two running modes — "Forward Only" for racing and "Forward and Backward" for scale operation and docking. The separate control-board/power-board layout improves anti-interference and reliability by isolating heat from the control circuitry.
5-Layer Protection & Programming
Start-up, over-heat, low-voltage cutoff, phase loss, and signal loss protection safeguard your investment. Configure via transmitter stick or ZTW LCD Program Card G2 (optional Phone App with adapter). Supports high-RPM motors and most motors on the market.
