The Tesla battery pack is something of a triumph of packaging. The battery pack is integrated into the skateboard-like chassis of the car, making a self-contained drivetrain-and-energy-storage unit that allows for really flexible body packaging.

They got this Model S battery pack from a wrecked Model S at auction, and they use the individual 24V battery packs in their own projects, since they’re such good batteries.

There’s more little bolts holding the thing together than what you’d find in an entire Ikea-furnished house, and there’s some fascinating custom-designed larger bolts, too.
