Specifications:Hobbywing 3A U-BEC UBEC (30pcs) Output: 5V/3A and 6V/3A switchableRipple: <50mVp-p(@2A/12V)Input: 5.5V-26V (2-6 cells Lipo battery pack or 5-18 cells NiMH battery pack)Size: 41.6mm*16.6mm*7mm (L*W*H)Weight: 11gFeatures:The UBEC is an advanced switching regulator with over-current and over-heat protection function,and the maximun efficiency of the system is nearly 90%.The small size and the light weight make it very convenient to use.The comparison of linear BEC and switch-mode BEC:When using a lithium battery pack more than 3S,a switch-mode BEC has much higher efficiency than linear BEC.For a traditional linear BEC,For example,a 4S lithium battery back 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 t
