I usually run my ez- b controller off of a 7.2v 3 amp rc battery with about 6 Servos running along with it, with no problems. But I like to use a werker 12v 12ah agm battery from the ez- b controller to run the sabertooth 2x15 which run 2 12v dc reversible gearhead motors 160rpms( is powered by 2 12v batterys), a 12v lighting system,a mp3 triggerandalso probablyanother servo controller which runs another gearheadmotor, which would be controler by a joystick controller probablythe ps3. Do you the this set up would be ok? Without burnning out anything? Or should add some sort of power converters 12v to 6vand 10 amp and 5amp fuse blocks?
Thanks for helping out
