The car does have a spare tire well. However, the structure for supporting the car and connecting to the back tires all connects together back there. There really isn't a good way to hack that up for installing batteries.

In the FRONT, "shoehorning" might be the right word to get more batteries in there. The problem is that batteries either fit.... or they don't.

You can't squish them. I did some measurements, and it MAY be possible to cram two more batteries in front, but IT'S SO CLOSE!

I wish the hood was flat instead of curved! I think that's one of the reasons that EV converters like old compact pickup trucks - everything is so nice and boxy!

To fit those two more batteries in front, I would have to build a custom battery box or rack. It would have to fit EXACTLY between the motor and the hood. To ever work on the motor, I would have to completely remove those batteries. Not that I ever need to "work on" the motor, but it's nice to at least see it when showing off the cars.

The other thing that I think might help is to at least have multi-battery monitoring. Because they are used batteries, and are in series, the weakest one limits the entire pack. Likewise, when charging, differences in voltage can cause problems in getting a really full charge.
