If you set the BEC to 12V mode but power it with a 2S or 3S LiPo, the output will likely be unstable. If you power with a 2S LiPo, the 7.4V output will also be unstable when the battery is at 70% or lower state of charge.

In this case, the supplier has two identical ESCs, but one just has a 35A label, and one has a 25A label and is priced lower, when the hardware is 100% identical. They also have a larger 55A version we might offer at a later date. It isn't clear what any given supplier uses as their test method to determine current ratings; often the best way to find out if an ESC works is just to try it out or ask others who have had success with it. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eDefault Firmware Config - Brushless Drive\u003c\/h4\u003e\n\u003cp\u003e\u003cimg\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0764\/3129\/4773\/files\/chrome_hiYJ1fwppg.png?v=1785951009\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0764\/3129\/4773\/files\/chrome_HSmdFz5oNc_600x600.png?v=1785951052\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003e*The 25A ESCs do get very hot with so much load, so don't use them for a 60lb combat bot. \u003ca href=\"https:\/\/photos.app.goo.gl\/jfijy9j86WHEgcTt9\" title=\"videos of open sauce bot nano ESC test\"\u003eThis was a quick test on our Open Sauce 2026 demo robot\u003c\/a\u003e. \u003c\/p\u003e","brand":"Just 'Cuz Robotics","offers":[{"title":"Standard","offer_id":53251844833589,"sku":"VIXEN-25A-STANDARD","price":14.5,"currency_code":"USD","in_stock":true},{"title":"BEC Included","offer_id":53251844866357,"sku":"VIXEN-25A-WITH_BEC","price":19.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/3129\/4773\/files\/VIXEN-25A-8.jpg?v=1785953502","url":"https:\/\/justcuzrobotics.com\/products\/vixen-nano-am32-brushless-esc-with-optional-bec","provider":"Just 'Cuz Robotics","version":"1.0","type":"link"}
