                                                            A BEC (battery elimination circuit) is a great tool for getting a lower voltage from a higher voltage system. For example, say you needed 5v to drive a Mini Turbo Fan on your 7.4v Hovercraft, but you didn't want to add a secondary battery just for the 5v fan. Simply plug this BEC into your Hovercraft's battery and you'll get a stable 5v 3A power supply. The 4X DC-DC Converter - 3A 5V Mini BEC is a small and lightweight UBEC, featuring a High efficiency switch mode design that provides better...
