Hyperion Switch-Mode BEC Unit with NET Noise Elimination Technology - 4A Sustained Rating, 5A Max, Selectable 5V or 6V Output, Use with up to 10S Lithium Packs, Compact and 20g!

Unlike standard BEC circuits, TICOOL-BEC is a switch-mode regulator. This means that it efficiently converts even 40V (10S) to match the receiver at 5V or 6V, selectable, without overheating. As such, the TICOOL can support as many as 8 standard servos (or as many as 6 Digital), almost regardless of the type of main pack used.
