For example, a 4S lithium battery pack has a typical voltage of 14.8V, in order to let BEC output 5V\/1A, the current flow into the BEC is at least 1A, so the power on BEC is 14.8V* 1A=14.8W. But the useful output power is only 5V*1A=5W, so the efficiency of the linear mode BEC is just 5W\/14.8W=33.8%, the redundant power 14.8W-5W=9.8W changes to heat, which makes the BEC very hot. \u003cbr\u003e-  For a switch-mode BEC in the above case, in order to let BEC output 5V\/1A, the current flow into BEC is only 0.38A (actual test data), so the power on BEC is 14.8V*0.38A =5.6W, and the efficiency of BEC is 5W\/5.6W=89.3%.\u003cbr\u003e-  Don’t worry about the polarity of battery pack. If the polarity is not correct, the UBEC can’t work, but it will not be destroyed. What you need to do is just swap the battery pack polarity.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eRemark:\u003c\/strong\u003e\u003cbr\u003eVoltage: 5V =Out 5V\/3A\u003cbr\u003eVoltage:12V=Out 12V\/3A\u003cbr\u003e \u003c\/div\u003e\u003cdiv\u003e\u003cstrong\u003ePackage Included:\u003c\/strong\u003e\u003c\/div\u003e\u003cdiv\u003e1 x Bluesky Mini UBEC Module\u003cbr\u003e \u003c\/div\u003e","brand":"Shopify","offers":[{"title":"Default Title","offer_id":31680871825498,"sku":"993056","price":177.72,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2787\/9162\/products\/SKU269738-1.jpg?v=1577695006","url":"https:\/\/electronic-pro-south-africa.myshopify.com\/products\/3a-ubec-module-low-ripple-bluesky-mini-switch-mode-dc-bec-5v-12v-2-6s-supply-for-rc-drone","provider":"Electronic Pro ","version":"1.0","type":"link"}
