For NiMH battery packs based on 2500 mAh cells, look for a "C" rating of 15C or higher. It would be most unwise to power the Arduino from the servo battery pack, as the Arduino would probably be destroyed by electrical noise and voltage spikes.
Use a 6v battery to power your servos. You will need an LDO regulator to produce the 5v supply for the Arduino, because 6v does not supply the necessary headroom to make the Arduino's voltage regulator operate properly. LDO regulators which should suit your purpose are available; use the parametric search engine at Mouser or Digi-Key or wherever.
If they are good quality AA cells one of those 6V packs should do the job. Connect battery + to all the servo + wires (usually red) and then the battery - to all the servo grounds (usually black) and also to the Arduino ground. And that's about it. Steve
6V: four AA or AAA alkaline batteries, five rechargeable NiMh cells or one 6V rechargeable lead acid pack; this is the maximum (and ideal) voltage most hobby servos can handle. Use these if your servos need a bit more power. 7.2V: six AA or AAA rechargeable NiMh batteries is perfect for 7.2V DC gear motors.
The servos need 6 V, and the Arduino either 5 V or 7-12 V via VIN. Somehow I need to supply two different voltages from the same battery source, which is something I have failed with before (tried powering 2 DC motors and a nano with AA batteries and a power converter, but could only get it to work with a separate 9 V battery for the nano).
No, in series for a servo. If 4 AA batteries in series can provide 2 A, then a single AA battery can provide 2 A. I have an AA alkaline battery from Asda (i.e. cheap) and it's not brand new but I can't remember what I used it for. It's been sitting on a shelf for a while. It easily produces 4.5 amps.

Your servo probably burned up because of the heat it generated. 5V is pretty much the safe spot for running a SG90 servo. The servo worked with the arduino and the 9v …
A 9V battery, no matter what kind, is a terrible choice for your project. They''re very low capacity. Energizer''s Ultimate Lithium 9V is only about 800mAh. That''s 7.2Wh, or …
Operating a normal hobby servo motor (rated at 4.8V to 6V) from a 9V to 12V battery would quickly burn it. What to do? The easiest option would be to use a smaller 12V …
You may find that even a fresh 4xAA battery pack is inadequate for four servos moving at once, however each pack can usually handle two servos. You can use more than one battery pack if you connect all …
The basic rule is that the servo power supply must be capable of delivering at least the stall current, times the number of servos. The MG996R stall current is 2.5 A. The S8218 stall current 7.5A. The battery lifetime …
