Appears no matter how careful you are, drive side battery housing breaks. You save up and treat it like your life depends on it and then it disintegrates itself. Same as everyone else, changed the battery and that was enough to allow for the failure to start. I can only assume moisture gets into the nuts, causing the metal to expand? Which in turns causes the cheap plastic to break as a result of a stress fracture. Query raised directly and I'm hopeful they'll offer a replacement or a fixing service. If the entire unit is now trashed, I look forward to the response as 4iiii backed with an industry leading 3-year warranty, or I'll join in the public outcry of not accepting such build quality.
