I'm not sure how to decide on capacity and am wondering if i could get away with something even smaller like a Varley Li5 @ 2.5lbs.
You need to do an electrical load analysis of the total normal operating and potential maximum current draw of your aircraft to determine which battery size/make you need before comitting to purchase.
Things like current draw of pitot heat is one to watch out for ususally taking 10amps or even more.
Have a read of the LAA doc that aerofurb has posted.
