The charging current is typically below 2A and is fluctuating wildly. The 'charger_status' field internal_error_flag is  True and 'const_current_mode' is fluctuating between True and False. Battery level was about 77% when I checked.\r\nWe recorded the 'battery_status' for a few hours - the rosbag is available here: https://lcas.lincoln.ac.uk/owncloud/index.php/s/FbRBWMZnZQQjVcQ.\r\n\r\nCan we do anything to figure out why is the charging slow ? normally it's about 10A.\r\n\r\nBest,\r\n\r\nTom"},"comment":{"url":"https://api.github.com/repos/strands-project/scitos_robot/issues/comments/208901386","html_url":"https://github.com/strands-project/scitos_robot/issues/72#issuecomment-208901386","issue_url":"https://api.github.com/repos/strands-project/scitos_robot/issues/72","id":208901386,"user":{"login":"marc-hanheide","id":1153084,"avatar_url":"https://avatars.githubusercontent.com/u/1153084?v=3","gravatar_id":"","url":"https://api.github.com/users/marc-hanheide","html_url":"https://github.com/marc-hanheide","followers_url":"https://api.github.com/users/marc-hanheide/followers","following_url":"https://api.github.com/users/marc-hanheide/following{/other_user}","gists_url":"https://api.github.com/users/marc-hanheide/gists{/gist_id}","starred_url":"https://api.github.com/users/marc-hanheide/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/marc-hanheide/subscriptions","organizations_url":"https://api.github.com/users/marc-hanheide/orgs","repos_url":"https://api.github.com/users/marc-hanheide/repos","events_url":"https://api.github.com/users/marc-hanheide/events{/privacy}","received_events_url":"https://api.github.com/users/marc-hanheide/received_events","type":"User","site_admin":false},"created_at":"2016-04-12T13:20:31Z","updated_at":"2016-04-12T13:20:31Z","body":"Thanks @creuther, so given all this, have your MetraLabs guys any advice how to best get rid of the heat build up? What did you do in Hobbit? \r\nTaking the skirt off is no option. I agree that what we see now is mostly consistent, and when it was cool, we saw indeed that `10 A - current_drawn = current_charge`. \r\n\r\nSo, the charger is functioning as it should, the firmware apparently isn't? Can we set the derated to false somehow? \r\n"}}
