All,
Selling two Swordfish 300A Lite controllers originally sold by Keith Bradley Boats. These are the Lite versions and do not include built-in data logging.
Each ESC has an external Hifei capacitor bank added. Both units were previously used in a twin catamaran setup.
For buyer confidence, each ESC was bench-tested under load using a 70 mm EDF fan on 4S LiPo on 12/15/2025. Tests confirmed proper operation, videos attached.
I am asking for $125 each, or $250 together.
ESC Programming: You can use the Hifei Program Box, or you can download the Hifei software V4.12 available on OSE:
