I have a Ford C-Max Engeri and most of my driving is commuting and I’m not using the truck area. It would be nice if there was a way to add extra batteries in the truck area to extend my commute and then on the occasions when I would need the truck area I could remove the extra batteries on those occasions. The other option that I wonder about is if it would be possible / feasible to get a solar array panel that would fit in the truck of the c-max that could charge the car while I’m at work.
