Maxpro BEC was developed by Maxpro Inc. in Sept. 2007, it is a switch mode BEC, specifically designed for high voltage, from 7v to 42v, it supports 2 - 10 cells lipo packs or up to 28 cells NiCD/NiMH, The 4A current rating is valid across M-BEC's entire input voltage range, allowing it to safely power multiple servos.

Input voltage 7v - 42v ,2 - 10 cells Li polymer or 6 - 28 cells NiCD/NiMH
Output current 4A cont / 6A burst
Output voltage 5v or 6v switchable
