I think the 60v or 80v ones would work well, the 40v would probably be fine too but it's almost like old technology at this point. And the other accessories to go with the battery you choose becomes a bigger choice than just the mower. I do have a Black and Decker 40v weed whacker and blower that works pretty good and it's 3-4 years old so I do like all the options available. This is good info guys. Lowes has the Greenworks 21" 80v 4a mower with battery and charger on sale for $399 which really looks like a decent deal. It's not self propelled but I don't need that.
