A 15.5 gallon tank is 58.5 liters. A Tesla S/X module[1] is 15.84 liters for ~5.3 kWh. If you could cram every inch of space with batteries it would come to just under 20 kWh. Not that much, and it will degrade quicker because you'll deeply discharge it more often.
That said, you can generally just line your trunk with batteries. You can jam 5 in the trunk of most cars while only losing ~3.5" of vertical space. Its a good idea to leave several inches for the crumple zone, but it's relatively safe if they are properly secured.
The best thing to do would really be to raise the floor and get low-profile sliders for your seats, but that's a real hassle.

- Hamuko 7y agoI'm still a bit iffy on the safety when it comes to the trunk. As far as I've understood, Teslas and the like have pretty good protection between the battery and you in case something bad happens. But there's not really that much of a separation between the interior and the trunk, like there is with the engine compartment with its firewall.
- kube-system 7y agoHybrids have customarily placed their batteries at the forward-most part of the trunk for as long as they have existed. The packs are typically inside of metal housings and vented to the outside of the car. For those extra concerned about fire or poorly designed packs, it's not difficult to add a rear firewall on most vehicles -- this is standard practice required by most motorsport organizations when adding a fuel cell to the rear of vehicles. "firewall" is just a fancy word for a compartment blocked off with a piece of sheet metal.
