3S-8S ZTW Seal ESC 130A SBEC G2 32 Bit Waterproof Large RC Boat ESC

ZTW Seal 105A SBEC G2 32-Bit Waterproof ESC 3-8S with Water Cooling for Racing Boats and Industrial Thrusters

32-Bit 170MHz Flagship Low-Voltage Power

The Seal 130A G2 is the top-current 3-8S model, combining a 170MHz 32-bit processor with 125A continuous output for large RC boats, high-performance catamarans, and heavy industrial marine thrusters demanding maximum 8S power.

125A Continuous / 135A Burst with Next-Gen MOSFETs

Advanced MOSFET technology provides low heat, instant current withstand, and high reliability. 125A sustained and 135A peak drives the largest 8S-compatible motors with confidence for big-block boats and heavy-lift subsea thrusters.

IP67 Waterproof + Dual-Channel Cooling

Full IP67 waterproof construction with two water-cooling pipes and custom heat sinks ensures efficient heat dissipation even in the confined, hot motor boxes of large boats.

8A Adjustable SBEC for Complex Setups

6.0/7.4/8.4V switching BEC at 8A powers multiple high-torque servos for dual rudder, trim tab, and reverse setups — eliminating the need for an external BEC.

Forward/Reverse & Freewheeling Efficiency

Dual running modes for racing or scale operation. Freewheeling circuitry reduces off-throttle drag, improving overall efficiency and runtime.

Full Protection Suite

Over-temperature power reduction protects the boat from thermal damage. Plus LVC, start-up, signal loss, phase loss, over-current, abnormal voltage, and over-load protection.

Telemetry & G2 Programming Ecosystem

Real-time current, voltage, temperature, RPM, throttle, and status telemetry via ZTW App or LCD Program Card G2. Full programming via Bluetooth app, LCD card, or transmitter stick.
