They are the Tower Pro SG90 9G mini servos
I was wondering if anyone had any tips or any products I should use. I would really appreciate any help.
(Those are micro servos actually, according to the servo label, although Amazon says mini. But that's an aside.)
I can't help with naming a battery by brand or chemistry, but can point you at this page which says you need the following current per motor:
So worst case is that if they all stall at once, you need to be able to supply 8x 730mA = 6A.
