Radiolink BEC Power Module, 5.45V 2.5A Output, 2-12S Input, for Pixhawk and Flight Controllers

Running a flight controller's logic straight off a battery-sensing power module works fine until that module needs to also handle voltage/current telemetry - which is exactly where a separate, dedicated BEC earns its place, supplying clean regulated power without tying the FC's electronics to whatever the battery monitoring circuit is doing. Radiolink's module accepts anywhere from 2S to 12S input and regulates down to a steady 5.45V at 2.5A, enough headroom for a Pixhawk-class flight controller plus its usual complement of peripherals, across the full range of pack sizes a builder might swap between.
