small battery

I have a 2014 D4 HSE, 1 large battery on near side, and a small battery on offside.
Question, what is the purpose of the small battery?

If the stop start mallarky is switched off, could the little battery be used as an aux battery for the like of an Engel? Or a bigger battery squeezed in?
