SportBEC is a switch-mode BEC specifically designed for sport planes, glow conversions, helicopters and more. It is designed for use with flight batteries from three to eight lithium cells, or up to 21 Nickel cells. The generous 3.5A current rating ensures a large safety margin when powering multiple servos. The product incorporates a throttle pass-through feature, which allows you to simply plug it in and go, without having to modify your ESC. SportBEC is designed for use with ESCs that are already lithium-aware and have the proper cutoff voltage.
