Seaking 90A V4 brushless ESC

Seaking 90A brushless ESC power controller with water cooling and data logging

Maximum reliability and durability, 4th generation Hobbywing Seaking series ESCs.

The Seaking controller series has been designed for use in fast boats. All regulators are water-cooled and have generously dimensioned connection nipples for the silicone hose.
Thanks to an up to 25 % narrower design and further optimised hardware, the regulators offer maximum performance and efficiency. In addition, the advanced software, high user-friendliness and numerous safety mechanisms that simplify operation are impressive. The integrated freewheeling function ensures a lower operating temperature, improves deceleration when releasing the throttle and improves steering control when cornering. This means more reactive acceleration and better overall handling - for an unrivalled riding experience on the water!

With a protection class of IP67, this controller offers excellent waterproof and dustproof properties. This ESC features a water cooling system that provides improved heat dissipation and ensures the ESC stays within a safe temperature range. The capacitor overheat protection helps prevent damage to the ESC caused by capacitor shutdown due to overload and protects the device from damage. Equipped with an internal logging module, this ESC can record the last 10 minutes of operation. If you connect to the mobile app, you can view the historical data (in graph format) after operation. This makes it easy to monitor the performance of the ESC and motor. Data is read out via the logging box programming card or via Bluetooth if an OTA module (optional) is connected.

The built-in BEC delivers up to 8A current, with switchable output voltages of 6V/7.4V and 8.4V. It easily powers high torque/HV servos and provides seamless and responsive control. By connecting the yellow signal cable to an unused receiver channel, the ESC parameters (e.g. reverse thrust) can be set in real time via the remote control. This "on the fly" utilisation enables simple "on the fly" tuning. With the programmable parameters, the ESC is tailored to the requirements of racing and offers a larger and more detailed selection of settings.
