What is the best power source for 8 mg90 servo motors & 2 arduino nanos? I have one 6v 4500 mah battery powering all those but the servos end up jittering after 15 minutes or so.
The mains would be the best power source, they do not discharge like a battery.
Sorry I do not do well with word problems. Post an annotated schematic showing exactly how you have
wired it Be sure to show all components used, connections, power connections, ground connections. Links to any hardware device including the Arduino that gives technical information. Frizzes do not count as schematics for me as they do not contain the needed information. Remember we are trying to find a problem not assemble it.
I expect those motors will draw about an amp when stalled and maybe 300mA when running. Then add on about 500mA for the Nanos. Your battery would have to supply (8 * 300) + (2 * 250) or 2900mA, this is not worse case or knowing what is connected. If you do not want to show your schematic this should show you what you need to do. From your description you have a bad battery (not eating its rating) or more load. This is just a guess as the needed data has not been supplied.
