You must seal all cable penetrations using waterproof connectors (e.g. AS150, XT150 with O-rings) or marine-grade silicone sealant. Or keep cable exit points above the waterline whenever possible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What motor is this ESC designed for?\u003c\/strong\u003e\u003cbr\u003eThe FD75200 is optimized for the \u003ca href=\"https:\/\/firduo.com\/products\/65162-100kv-120kv-motor\" style=\"color: rgb(0, 0, 255);\" target=\"_blank\"\u003eFirduo 65162 120KV Waterproof Motor\u003c\/a\u003e in eFoil and electric surfboard applications. It is also compatible with any BLDC motor that operates within the 14–75V \/ 200A continuous range. Sensored (ABI, HALL, AS5047, AS5048A) and sensorless operation are both supported.

The three-pipe cooling block is built into the ESC. You need to connect a small external water pump (12V, 3–5 L\/min flow rate recommended) and hoses to circulate water through the cooling block. Use silicone hose rated for 60°C+. Ensure the cooling loop is primed and air-free before powering on. Without active cooling, the ESC will overheat and trigger thermal protection at high current.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: How do I configure the ESC, and is VESC Tool required?\u003c\/strong\u003e\u003cbr\u003eThe FD75200 is based on the VESC open-source platform and is configured using \u003ca href=\"https:\/\/vesc-project.com\/\" style=\"color: rgb(0, 0, 255);\" target=\"_blank\"\u003eVESC Tool\u003c\/a\u003e (free download for PC\/Mac\/Linux). Connect via USB, run the motor detection wizard, and set your current limits, throttle curve, and protection thresholds. While the ESC ships with default settings that work for most builds, we strongly recommend running motor auto-detection for optimal performance.

Use a high-current connector rated for 200A+ — AS150, XT150, or equivalent anti-spark connectors are recommended.

You must power your receiver or remote receiver separately using a standalone BEC (5V regulated) or a small receiver battery. Connect the BEC output to the receiver's power input, and connect the ESC signal wire (JR male) to the receiver's throttle channel. Do not attempt to draw receiver power from the ESC's signal wire.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: How does the water cooling work, and is it required?\u003c\/strong\u003e\u003cbr\u003eThe Sea Lion 120A uses \u003cstrong\u003eactive water cooling\u003c\/strong\u003e via a 4.6mm cooling pipe. Water is drawn from your board's water intake, circulated through the ESC's internal cooling channel, and expelled. This is required for sustained high-current operation — without water cooling, the ESC will overheat at 120A loads. Brief low-power testing without cooling is acceptable, but always ensure water flow before full-power riding.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Can I use the Sea Lion 120A with a VESC-based remote like the VX3?\u003c\/strong\u003e\u003cbr\u003eThe Sea Lion 120A uses \u003cstrong\u003estandard PPM signal input\u003c\/strong\u003e — it is not a VESC-based ESC and does not support UART communication.

You must power your receiver or remote receiver separately using a standalone 5V BEC connected to your battery, or a small receiver battery pack. Connect the BEC output to the receiver's power input, and connect the ESC signal wire (JR male) to the receiver's throttle channel. Do not attempt to draw receiver power from the ESC signal wire.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Is water cooling mandatory, or can I run it air-cooled?\u003c\/strong\u003e\u003cbr\u003eWater cooling is \u003cstrong\u003estrongly recommended and is the primary thermal management method\u003c\/strong\u003e for this ESC. At 200A continuous, the ESC generates significant heat that cannot be dissipated by air alone. Running without water cooling at high current loads will trigger over-heat protection and may permanently damage the ESC.

The key difference is cooling: the \u003cstrong\u003eFD200\u003c\/strong\u003e 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.

Choose \u003cstrong\u003eWalrus 30A\u003c\/strong\u003e for lower-power motors and lighter SUP\/kayak builds where sustained current is below 30A.

The signal cable's Red wire provides 6V to power your receiver directly — no separate BEC is required.

The ESC body can be submerged. However, \u003cstrong\u003ecable connection points\u003c\/strong\u003e (battery, motor, signal cable terminations) are not inherently waterproof — ensure all solder joints and connector terminations are sealed with appropriate waterproofing (heat-shrink with adhesive, potting compound, or waterproof connectors) before submerging.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What motor is recommended for the Walrus ESC?\u003c\/strong\u003e\u003cbr\u003eThe Walrus ESC is optimized for the \u003ca style=\"color: rgb(0, 0, 255);\" href=\"https:\/\/firduo.com\/products\/4310103556173\" target=\"_blank\"\u003eFirduo 65111 150KV IP68 Waterproof Motor\u003c\/a\u003e for SUP and kayak propulsion builds at 10S–14S.

It uses the STM32F4 MCU and supports the full VESC feature set including FOC, CAN bus, and all sensor types.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What motors is it compatible with?\u003c\/strong\u003e\u003cbr\u003eIt supports brushless (BLDC), brushed DC, and IPM motors. Sensor support includes sensorless, HALL, ABI encoder, AS5047, and AS5048A. Motor temperature sensors (NTC 10K\/100K, PTC 1K, KTY83\/122) are also supported. In short: if it's a common electric motor type, this ESC can drive it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Is the waterproofing sufficient for eFoil \/ underwater use?\u003c\/strong\u003e\u003cbr\u003eThe ESC body is sealed to 5 meters depth. The wire exit point is not fully sealed — for underwater installations, wrap the cable exit with self-amalgamating tape or use the optional 120A waterproof connectors (available in the bundle variant) to seal the phase connections. The ESC is designed for eFoil and water sports use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Can I run two ESCs in a dual-motor setup?\u003c\/strong\u003e\u003cbr\u003eYes. The CAN bus interface allows multiple Manatee 100 Pro units to be daisy-chained for synchronized dual-motor control. This is commonly used in dual-drive electric skateboards and twin-thruster watercraft. Configure master\/slave roles in VESC Tool.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Do I need the waterproof connector bundle, or can I use my own connectors?\u003c\/strong\u003e\u003cbr\u003eThe base \"M 100 PRO\" variant ships without phase connectors — you can solder your own (XT60, MR60, or bare wire). The \"M 100 PRO + Waterproof Connectors ×3\" bundle includes 3× Firduo 120A waterproof connectors, which are recommended for any wet or submerged installation to prevent corrosion and short circuits.\u003c\/p\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg style=\"margin-bottom: 16px;\" alt=\"Firduo ESC compatibility overview\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/f4b3da9554de4e60ffd11b8edcb16ff8_2c894297-2540-4c2f-b0d5-04fccb3d1fd7_1024x1024.jpg?v=1775614803\"\u003e\u003c\/div\u003e","brand":"FIRDUO","offers":[{"title":"M 100 PRO","offer_id":47276323045554,"sku":null,"price":109.0,"currency_code":"USD","in_stock":true},{"title":"M 100 PRO+Waterproof connectors *3","offer_id":47276323078322,"sku":null,"price":139.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/3_b72bb3dc-98f3-4872-9f5a-4d1f407f587f.jpg?v=1775615629"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/collections\/V6_200A-2_540x_24a8b777-4d45-495f-a19d-cd775ade89be.jpg?v=1776527636","url":"https:\/\/firduo.com\/collections\/firduo-esc\/200a-esc.oembed","provider":"Firduo","version":"1.0","type":"link"}
