dual switching BECs into Power Expander?
If I need to reduce the voltage that I'm running servos at, one of my options might be to put two BECs between the two 2S lipo batteries and my Power Expander 14MZ. Some switching BEC manufacturers (notably Castle Creations on the CC BEC Pro) caution people not to run their BECs in parallel. Do you know if there is likely to be a problem when switching BECs are used with the power expander in this manner (will the circuitry in the power expander isolate the two supplies such that there won't be a problem)?
