Hy all, I'm new here and looking for help - my 220 AC has a very short mowing time, and I don't understand why, when it is fully charged and starts mowing it takes a maximum of about 10 minutes and then it starts looking for a charger. The battery seems ok, ie at that moment it shows only a small consumption on the screen. Then charge for about ten minutes and then mows for a few minutes and so on. Does anyone have any idea why this is happening and what to do?
