100A ZTW Shark G2 ESC Waterproof 4S-6S 8A SBEC 100A Speed Controller

ZTW Shark G2 100A 32-Bit Waterproof ESC 4-6S with Water Cooling and 8A SBEC for RC Boats and Light Underwater Thrusters

32-Bit High-Current 4-6S Boat ESC

The Shark G2 100A brings 100A continuous output to the 4-6S platform, driven by a 32-bit microprocessor for fast response, smooth start-up, and accurate throttle linearity — engineered for large RC boats and heavy lightweight underwater thrusters.

100A Continuous / 120A Burst on 4-6S

New-generation MOSFET technology ensures low heat generation and high reliability under extreme instant current loads. 100A sustained and 120A peak on 4-6S LiPo handles the most demanding 6S motor and prop combinations with authority.

Splash-Proof + Flat Water Cooling

Waterproof-glued construction resists splash and spray, while the 32mm flat water-cooling system efficiently dissipates the elevated heat of 100A operation — essential for large boats and high-power subsea thrusters.

8A Adjustable SBEC for Complex Setups

The 5.0/6.0V switching BEC delivers 8A continuous (15A burst), powering multiple high-torque servos, lights, and auxiliary devices — no external BEC required for large boats or small industrial ROVs.

Synchronous Rectification Efficiency

Synchronous rectification dramatically reduces ESC heating at high currents, improving overall powertrain efficiency and conserving battery energy — critical for sustained high-power operation.

Forward/Reverse & Separate Board Design

Dual running modes for racing or scale/docking. The isolated control-board/power-board architecture improves EMI resistance and reliability, ensuring the control circuit remains stable even when the power stage runs hot.

Comprehensive Protection & Programming

Five-layer protection (start-up, over-heat, LVC, phase loss, signal loss). Program via transmitter, LCD Program Card G2, or optional App. 10-gauge power wires handle high current. Same 89×45×13mm, 105g footprint as the 120A for scalable designs.
