ZTW Shark G2 30A 32-Bit Waterproof ESC 2-4S with Water Cooling and SBEC for RC Boats and Light Underwater Thrusters

32-Bit Performance for Mid-Small RC Boats

The Shark G2 30A pairs a 32-bit microprocessor with an improved algorithm for faster response, ultra-smooth start-up, and precise throttle linearity — perfect for medium-small sport boats, fishing RC boats, and lightweight underwater thruster systems.

30A Continuous / 40A Burst on 2-4S

New-generation MOSFET technology ensures low heat generation and high reliability under instant current loads. 30A sustained and 40A peak on 2-4S LiPo handles more powerful motors in the popular 2-4S battery configuration.

Splash-Proof + Flat Water Cooling

Waterproof-glued construction provides splash resistance, while the flat water-cooling design efficiently dissipates heat — ideal for small-to-medium boat motor boxes and compact underwater electronics compartments where space is limited.

4A Adjustable SBEC

The 5.0/6.0V switching BEC delivers 4A continuous, powering receivers and multiple standard servos for dual-rudder or auxiliary-equipped boats without an external UBEC.

Synchronous Rectification — Cooler & More Efficient

Synchronous rectification cuts ESC heat significantly, boosting driving efficiency and conserving battery power for longer run times on the water or extended lightweight underwater operation.

Forward/Reverse & Isolated Board Design

Switch between "Forward Only" racing mode and "Forward and Backward" for scale use and docking. The separate control-board/power-board architecture enhances anti-interference and reliability by thermally isolating the control circuit.

Comprehensive Protection & Programming

Five-layer protection: start-up, over-heat, LVC, phase loss, signal loss. Program via transmitter or LCD Program Card G2 (optional App adapter). Compatible with high-RPM and most market motors. Ultra-compact at 60×33×10mm and just 36g.
