I imagine it wouldn't (need to) handle particularly differently. You can pretty much put a battery wherever you like. It seems that in the Pipistrel WATTsUP removable battery modules replace the mass of the engine block. A nice advantage for a trainer is that unlike a combustion engine aircraft, a battery powered aircraft's mass isn't changing over time, so the learning pilot can expect a more consistent handling experience.
