The charger IC on the mainboard will stop charging the battery for this brief interval but will charge again as soon as the power-supply reaches 5V again. This sequence is so fast that it will destroy your battery, and possibly your camera, in no time.
In summary, the BEC must be able to supply 1A under power. 550mA is not enough.
considering i am using this ESC http://hobbyking.com/hobbyking/store...dProduct=32475
it should be enough to power 4 12gram servo 1 180degree pan servo and receiver itself. it can probably supply 1 A current for the cam. however it listed as 5,5v. this can be a problem as you guys said.. what is margin of this mobius? probably i should hook up multimeter and test the voltage all servos connected and not.
