There is no VESC Tool setup, motor detection, or parameter tuning required. Simply connect your battery and PPM\/PWM remote signal — the system is ready to use out of the box. This makes it ideal for builders who want a plug-and-ride solution without technical ESC configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: What battery do I need, and what connector is required?\u003c\/strong\u003e\u003cbr\u003eThe system supports 10–14S (36–58.8V). For SUP and kayak use, a 12S–13S LiPo or Li-ion pack with minimum 30A continuous discharge is recommended. Ensure your battery has a matching waterproof connector.

The VX3 is rated \u003cstrong\u003eIP67\u003c\/strong\u003e — it can be submerged to 1 meter for up to 30 minutes. It is designed for water sports use and will survive splashes, rain, and brief submersion. The wireless charging port is sealed, so there are no exposed charging ports to worry about. Rinse with fresh water after salt water use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Can I use this kit with my own remote instead of the VX3?\u003c\/strong\u003e\u003cbr\u003eYes. The TUNA TT160-A2 accepts  standard \u003cstrong\u003ePPM\/PWM signal\u003c\/strong\u003e, so it is compatible with most RC receivers and remotes. The VX3 is included in this kit for convenience, but if you already have a compatible PPM remote, you can use it instead. Please note that a waterproof remote control is recommended for water sports.\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"max-width: 100%;\" alt=\"Firduo TUNA TT160-A2 VX3 kit package contents overview\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/e462aee6a7ec9fd3fc77234538abd363.jpg?v=1694684622\"\u003e\u003c\/p\u003e","brand":"FIRDUO","offers":[{"title":"TT160-A2-1 （CW）KIT","offer_id":47580516843698,"sku":"TT160-A2-1 （CW）KIT","price":619.0,"currency_code":"USD","in_stock":true},{"title":"TT160-A2-1（CCW）KIT","offer_id":47580516876466,"sku":"TT160-A2-1（CCW）KIT","price":619.0,"currency_code":"USD","in_stock":true},{"title":"TT160-A2-2 （CW）KIT","offer_id":47580516909234,"sku":"TT160-A2-2 （CW）KIT","price":619.0,"currency_code":"USD","in_stock":true},{"title":"TT160-A2-2（CCW）KIT","offer_id":47580516942002,"sku":"TT160-A2-2（CCW）KIT","price":619.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/2_5e016771-c2a0-4604-8581-f93831264f9c.jpg?v=1781444621","url":"https:\/\/firduo.com\/products\/firduo-tuna-1500w-18-5kgf-electric-fin-vx3-kit-sup-kayak-surfboard","provider":"Firduo","version":"1.0","type":"link"}
