Today I'm struggling to actually utilize the 160kg (380lbs) of batteries in my trunk. You see, you can just put batteries in your car, but that doesn't magically use them. May seem obvious to the 'experts' in here, but I was thoroughly baffled. Fortunately, after using these devices called 'wires' to connect them to the car, everything worked fine and I drove 110mi (170km) on a single charge, which is quite a lot for a 2011 Nissan Leaf in winter. Oh also, the 12V battery keeps depleting. Nobody reads these descriptions so that's why it makes no sense at all.
