You should sketch what YOU mean. What are 2x2s2p ? You can't really parallel batteries without "sharing" resistors, to prevent huge internal currents flowing.

First of all, are these all the same technology ? Are they the same AGE ? Arrays of batteries are highly problematic, especially if they have different discharge histories, and mixing technologies is a recipe for disaster/fire/explosion.
