Manufacturers also need to come away from the 12V battery mindset. They aren’t ICE and don’t need one, when they could easily get 12V from the battery lump in the floor and would dee a common issue sorted.
The only problem doing that is that using auxiliary items then drains the main battery, even if only by a little bit. I bet the 12v battery is much cheaper than the gubbins required to get 12v from the big’un.
