ZTW Shark G2 30A 32 Bit ESC 4S With Water Cooling RC Boat ESC
The ZTW Shark G2 30A is a 32-bit waterproof ESC delivering 30A continuous and 40A burst on 2-4S LiPo. With splash-proof glued design, flat water cooling, 5V/6V 4A SBEC, synchronous rectification, forward/reverse modes, and separate control/power boards for RC boats and small unde
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.
