💪 High Current. Aluminum Tough. VESC Inside.

The Firduo FD200 is a 75V 200A aluminum-case ESC built on the open-source VESC platform — engineered for eFoil, RC boat, electric surfboard, and high-power DIY builds that demand sustained high-current performance with reliable thermal management. The full aluminum cooling shell (113 × 102 × 33mm) provides excellent passive heat dissipation, making it ideal for air-cooled enclosure installations where water cooling is not available or preferred.

With 200A continuous / 300A peak current, support for 3S–16S (14–75V), and full VESC Tool configurability via USB/CAN/UART, the FD200 is a versatile, proven ESC for builders who want open-source flexibility in a robust aluminum package.

🛠️ Setup Guide

1. Mount the ESC — secure the aluminum case in a dry, ventilated enclosure. The aluminum shell provides passive cooling — ensure adequate airflow around the case. Do not obstruct the aluminum fins or surfaces.
2. Connect motor wires — plug the 3× 8AWG phase wires (A-B-C) into your motor. Phase order can be corrected in VESC Tool if the motor spins in the wrong direction — no rewiring required.
3. Connect battery — use a high-current connector (XT150, AS150, or equivalent) rated for 200A+ continuous on the 10AWG power cable. Verify battery voltage is within 14–75V before connecting. Use an anti-spark switch or pre-charge resistor to prevent connector damage.
4. Connect sensor (if used) — plug the motor sensor cable into the ESC sensor port. Supports ABI, HALL, AS5047, AS5048A. Sensorless mode is also available if no sensor is present.
5. Connect remote receiver — plug the PPM cable (included) into the ESC PPM port and connect to your remote receiver signal output. For UART remotes, use the UART port instead.
6. Configure via VESC Tool — connect via USB (cable included). Run the motor detection wizard, set current limits (max 200A continuous), configure throttle curve, and set protection thresholds. Save configuration before disconnecting.
7. Test at low power first — start at 20–30% throttle in a safe environment. Monitor ESC temperature after the first run — the aluminum case should be warm but not too hot to touch. Increase power gradually.

❓ FAQ

Q1: What's the difference between the FD200 (aluminum case) and the FD75200 (water-cooled)?
Both ESCs share the same VESC-based platform and 200A continuous / 300A peak current rating. The key difference is cooling: the FD200 uses a full aluminum case for passive air cooling — ideal for dry enclosures with airflow, e-bikes, RC boats, and builds where water cooling is impractical. The FD75200 uses an active three-pipe water cooling system — better suited for sustained high-current eFoil and electric surfboard use where the ESC may be in a sealed, hot enclosure. Choose FD200 for air-cooled builds; choose FD75200 for water-cooled marine builds.

Q2: Is the FD200 waterproof? Can I use it in an eFoil?
The FD200 aluminum case is not waterproof — it must be installed inside a sealed, waterproof enclosure for eFoil or marine applications. The aluminum case provides excellent passive cooling and corrosion resistance, but the electronics must be protected from water ingress. Seal all cable entry points with waterproof grommets or silicone sealant. For builds requiring a fully submersible ESC, consider the FD75200 water-cooled ESC.

Q3: How do I configure the ESC, and is VESC Tool required?
The FD200 is based on the VESC open-source platform and is configured using VESC Tool (free download for PC/Mac/Linux). Connect via the included USB cable, run the motor detection wizard, and set your current limits, throttle curve, and protection thresholds. The ESC ships with default settings that work for most builds, but we strongly recommend running motor auto-detection for optimal performance. Our support team can provide a recommended config file on request.

Q4: What motor is compatible, and what connectors do I need?
The FD200 is compatible with any BLDC motor operating within 14–75V / 200A continuous. It is optimized for the Firduo 65162 120KV Waterproof Motor. For the battery connection, use a high-current connector rated for 200A+ (AS150, XT150, or equivalent). For motor phase connections, 8.0mm gold bullet connectors are recommended.

Q5: What battery do I need, and what voltage is safe?
The FD200 supports 14–75V (3S–16S). For eFoil and high-power builds, a 12S–16S LiPo or Li-ion pack with minimum 200A continuous discharge (300A burst) is required for full-power operation. The safe operating voltage is up to 75V — do not exceed 16S (67.2V fully charged for LiPo) to maintain a safety margin. Always use an anti-spark connector or pre-charge resistor to prevent connector damage when first connecting the battery.
