ZTW Seal 350A HV SBEC G2 32-Bit Waterproof ESC 6-14S Flagship with 12V SBEC and Water Cooling for Giant RC Boats and Industrial Marine Propulsion

32-Bit 170MHz Flagship Extreme-Power HV ESC

The Seal 350A HV SBEC G2 is the most powerful ESC in the entire Seal G2 series, pairing a 170MHz 32-bit processor with 350A continuous output for giant-scale RC boats, heavy commercial surface vessels, large subsea thrusters, and industrial marine propulsion.

350A Continuous / 450A Burst with Advanced MOSFETs

Next-generation MOSFET technology delivers low heat generation and withstands extreme instant current surges with high reliability. 350A sustained and 450A peak delivers up to ~19.8kW at 14S — propelling the largest racing boats and driving heavy multi-thruster ROV systems.

IP67 Waterproof + Massive Dual Water Cooling

Full IP67 waterproof construction with two water-cooling pipes and oversized customized heat sinks manages the extreme thermal load of sustained 350A operation, even in passive-cooling configurations.

12V 10A SBEC for Complex Auxiliary Systems

The 6.0/7.4/8.4/10/12V adjustable BEC supplies 10A, powering control electronics and 12V industrial auxiliary systems — pumps, lighting, winches, and telemetry — common on large boats and commercial subsea vehicles.

Forward/Reverse & Freewheeling

Dual running modes cover racing and operational requirements. Freewheeling technology improves driving efficiency and conserves battery energy during coasting.

Comprehensive Protection Suite

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

Telemetry & G2 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 stick.
