Waterproofing the ESCs

26 October 2026

The first step to building the ROV is to waterproof the ESCs. Two of them are 20A water-cooled ESCs. These are for the main drive motor. The third is a standard 40A ESC that will be adapted to water cooling with an aluminum water block.

Important Note: They are all bidirectional which is critical for ROV control.
