ZTW Seal 200A SBEC G2 4S-8S ESC Giant RC Boats ZTW 200 Amp ESC

ZTW Seal 200A SBEC G2 32-Bit Waterproof ESC 4-8S with Water Cooling for Giant RC Boats and Heavy Industrial Marine Propulsion

32-Bit 170MHz Extreme 8S Power

The Seal 200A G2 is the most powerful low-voltage model, pairing a 170MHz 32-bit MCU with 200A continuous output for giant-scale RC boats, heavy commercial surface vessels, and large underwater thrusters requiring massive 4-8S current.

200A Continuous / 240A Burst with Advanced MOSFETs

Next-generation MOSFETs deliver low heat generation and withstand instant high-current surges with high reliability. 200A sustained and 240A peak handles the most demanding 8S motor setups — from twin-motor racing catamarans to heavy-lift ROV thrusters.

IP67 Waterproof + Dual Water Cooling

Full IP67 waterproof rating with two water-cooling pipes and customized heat sinks manages the elevated thermal load of sustained 200A operation, even in water-cooled boat installations and sealed subsea compartments.

10A Adjustable SBEC for High-Load Electronics

The upgraded 6.0/7.4/8.4V switching BEC supplies 10A continuous — enough for multiple HV digital servos, lights, pumps, and auxiliary electronics on large boats and industrial vehicles without a separate UBEC.

Forward/Reverse & Freewheeling

"Forward Only" and "Forward and Backward" modes cover racing and operational needs. Freewheeling technology improves driving efficiency and saves energy during coasting.

Comprehensive Protection Suite

Thermal power reduction, LVC, start-up, signal loss, phase loss, over-current, abnormal power-on voltage, and over-load protection all standard — essential safety for extreme-power marine systems.

Telemetry & Multi-Platform Programming

Real-time data returning (current, voltage, temperature, RPM, throttle, status) via ZTW App or LCD Program Card G2. Full configuration via Bluetooth app, LCD card, or transmitter.
