We have done research to solve our problem but have had no luck. We are afraid that we might have the same problem next year because we can fix it if we can't diagnose it! Can anyone help? Thanks

^This.

Or some part of your electrical system is damaged. Or the batteries are just getting old. Does this happen to every robot it's plugged into or just one? How old are the batteries? Any idea how many charge cycles they have been through? Ever load-tested any of your batteries?
