why that last - do they have only a single battery for all four motors? I would have thought in a vehicle this size, that splitting the battery bank into controllable sections would make ultimate sense. If a part of the power pack fails, just shut that off and get the service agent to replace it at the next convenient place. which reminds me of the old trope about Rolls Royce, where dealers were supposed to have a replacement vehicle ready to go in the back of an unbranded lorry at all times so that if you broke down, they could show up and get you off the side of the road in short order, avoiding bad press and maintaining their image of never failing.
