NHRA Battery Rules

Besides the NHRA rule that states batteries must be the same size can I use 2 different size batteries? This is a stock style bracket car and I want to switch from 2 red tops to 1 red top and a braille. I like the 2 battery for the amperage but trying to reduce weight. With the 2 size batteries I can save 14 lbs but not sure if charging will treat both batteries equally or will the smaller one get over charged.
