Seal 120A Opto ESC (6-12 Cells)
Brand: ZTW
Part No: ZTW6120400
Shadow Stock: Usually ships next day
The ZTW Seal 120A Opto ESC (part number ZTW6120400) is a water‑cooled, brushless speed controller engineered for marine use. Built around new low‑resistance FETs and enhanced water‑cooling, it is designed to manage heat more efficiently so you can access higher power levels with confidence. A carefully tuned MCU and efficient firmware deliver fast motor sync and precise throttle control, making performance predictable and responsive run after run.
ZTW has increased the cooling area with additional water‑pipes, helping to dissipate heat faster and more evenly across the controller. The result is a robust package that balances performance, reliability and longevity. A suite of safety functions adds peace of mind, including over‑temperature protection, power arming protection, and automatic throttle shut‑down if the signal is lost. With support for high RPM motors and smooth, accurate throttle linearity, this Seal series ESC is a strong choice for high‑performance RC boat applications where consistent delivery matters.

Beautifully designed and manufactured, the new SEAL marine range of water-cooled brushless speed controllers by ZTW use new FETs that offer less resistance and less heat dissipation. ZTW has added additional water-pipes to increase the cooling area and so dissipate heat faster and with greater efficiency. The result enables higher power levels without fear of burning out the controller. Add to this a well-designed MCU with efficient code that makes for a faster sync and accurate control, and within this competitively priced package is a recipe for performance, reliability, and longevity.
