OverviewThe FT85CS waterproof ESC is engineered for high-power electric water-sports and compact marine propulsion. It accepts 4–20S battery packs (14–85V) and delivers a stable 150A continuous current with 250A peak capability, suitable for electric surfboards, underwater thrusters and small remote vessels.
Key Features- Waterproof design for marine and water-sports propulsion projects
- Wide operating voltage: 14–85V (compatible with 4–20S battery systems)
- 150A continuous current; 250A peak current
- Multiple communication/control interfaces: USB, CAN, UART, PPM, ADC
- PWM variable frequency control, regenerative braking and multi-gear speed limiting
- Supports current, duty-cycle and speed control modes
- Integrated protections: low-voltage, over-voltage, MOS over-current, battery over-discharge and MOS over-temperature
