ZT-7300410 - ZTW Seal 300A HV OPTO G2 - 6-14S LiPo - OPTO
The ZTW Seal 300A HV OPTO G2 is a high-end waterproof brushless ESC designed for very demanding RC boat and marine applications. With 300A continuous current, 360A peak current and support for 6-14S LiPo battery setups, this ESC is built for extreme high-power electric boats that require maximum current handling, smooth throttle response and reliable operation under heavy load.
The Seal G2 series uses a high-performance 32-bit microprocessor with fast processing speed for accurate throttle control, smooth start-up and stable motor operation. The compact G2 design is lighter, shorter and narrower than the previous generation, making installation easier in large performance boat hulls. The IP67 waterproof design, dual water-cooling pipes and customized heat sinks help protect the ESC and support reliable performance in demanding marine conditions.
This is an OPTO ESC, which means it has no built-in BEC. The receiver and steering servo must therefore be powered by a separate receiver battery or an external UBEC system. This design is especially suitable for extreme marine power systems where an independent receiver power supply is preferred.
The ZTW Seal 300A HV OPTO G2 supports real-time data return, allowing current, voltage, temperature, RPM, throttle status and ESC status to be checked with compatible ZTW programming equipment. It also supports Forward Only and Forward/Reverse running modes depending on the programmed setup and can be programmed via transmitter setup, optional ZTW LCD programming card or optional ZTW Bluetooth module/app.
