2S-4S ZTW Shark G2 50A 32 Bit Waterproof ESC Speed Controller
The ZTW Shark G2 50A is a 32-bit waterproof ESC delivering 50A continuous and 65A 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 underwater
ZTW Shark G2 50A 32-Bit Waterproof ESC 2-4S with Water Cooling and SBEC for RC Boats and Light Underwater Thrusters
32-Bit Power for Performance 2-4S Boats
The Shark G2 50A combines a 32-bit microprocessor with an improved algorithm for faster computing, smoother start-up, and more accurate throttle linearity — the top choice for high-performance 2-4S RC boats and medium underwater thruster systems.
50A Continuous / 65A Burst on 2-4S
New-generation MOSFETs deliver low heat generation and instant high-current withstand capability. 50A sustained and 65A peak on 2-4S LiPo provides generous headroom for aggressive 2-4S motor and prop combinations.
Splash-Proof + Flat Water Cooling
Waterproof-glued construction handles splash and spray, while the flat water-cooling design efficiently dissipates heat during sustained full-throttle runs — essential for performance boats pushing 2-4S limits.
4A Adjustable SBEC
The 5.0/6.0V switching BEC supplies 4A continuous for receivers and servos. Adjustable output supports both standard and HV digital servos for precise, powerful steering.
Synchronous Rectification for Cooler Operation
Synchronous rectification significantly reduces ESC heating, improving efficiency and conserving battery energy — extending run time and reducing thermal stress in compact installations.
Forward/Reverse & Isolated Board Design
Dual running modes for racing or scale/docking use. The separate control-board/power-board architecture enhances anti-interference and reliability, isolating the control circuit from power-stage heat.
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). Supports high-RPM motors. Same ultra-slim 69×33×9mm, 45g footprint as the 40A for easy upgrades.
