Purchased JD for son for Christmas. Battery will not charge. Lights flash 6x indicating 300mv difference of voltage. Followed instructions on website to disconnect from robot and try again. Still not charging. Connected to website and checked the battery as per web instructions. Info reads CPU temperature 24.37c Input vol 5.42. What do we do? Is there anyway to contact a rep for the company? Not comfortable about there being no direct link to them. We have not had robot on for more that 5-10 minutes.
