Currently I have .2 acres to mow and either of these models should work but I also don't want to wait 2 days for the mower to finish the entire grass. I see that the 320 has a 5 AH battery and the 310 has a 4 AH battery so the 320 should work longer but also take 20 minutes more to charge each time. My lawn is simple with no obstructions on the grass and has concrete and fence borders. I am interested in hearing what others have experienced to see if the 310 will mow the .2 acres in 12 hours or less.

This is the RTK version I should say.

It takes about 2 hours to charge which seems like a long time when you want it to be mowing. Is that a typical time? My old Worx landroid charges in one hour and works longer.
