105A Seal SBEC G2 ZTW 3-8S ESC For Racing Boats And Industrial Thrusters
The ZTW Seal 105A SBEC G2 is a 32-bit 170MHz waterproof ESC delivering 105A continuous and 115A burst on 3-8S LiPo. With IP67 rating, dual water cooling, 8A adjustable SBEC, forward/reverse, telemetry, and APP/LCD programming for high-performance marine use.
ZTW Seal 105A SBEC G2 32-Bit Waterproof ESC 3-8S with Water Cooling for Racing Boats and Industrial Thrusters
32-Bit 170MHz — Performance Sweet Spot
The Seal 105A G2 pairs a 170MHz 32-bit MCU with 105A continuous output, making it the performance sweet spot for 8S RC racing boats and medium industrial marine thrusters. Super smooth start-up and precise throttle linearity give competitors the edge.
105A Continuous / 115A Burst with Advanced MOSFETs
New-generation MOSFETs deliver low heat generation and instant high-current withstand capability. 105A sustained and 115A peak on 3-8S drives high-kv racing motors and large thruster motors with authority.
IP67 Waterproof + Dual Water Cooling
IP67 full waterproof rating handles the harshest marine conditions. Two integrated water-cooling channels with customized heat sinks ensure optimal thermal management during prolonged full-throttle racing runs.
8A Adjustable SBEC
The 6.0/7.4/8.4V switching BEC supplies 8A for receivers and multiple high-torque servos — ideal for racing boats demanding precise, high-speed steering control.
Forward/Reverse Modes & Freewheeling
"Forward Only" for pure racing, "Forward and Backward" for recovery and docking. Freewheeling technology improves efficiency and saves battery energy during coasting.
Comprehensive Protection
Thermal power reduction, LVC, start-up, signal loss, phase loss, over-current, abnormal voltage, and over-load protection — a full safety net for competitive and commercial use.
Telemetry & Multi-Platform Programming
Real-time data returning via ZTW App or LCD Program Card G2. Configure via Bluetooth app, LCD card, or transmitter. Supports high-RPM motors and is compatible with most motors on the market.
