It takes a lot of energy to push a car size object a few hundred miles. Either a few liters of gasoline or several thousand lithium batteries will get the job done. There are certainly many batteries, and much more potential to be unlocked for their use than throwing bits of metal around on wheels. If you have an idea on how to better use the batteries for something else, it's certainly an option, although it's not always as easy as it looks.
In this video, [Kerry] on [EVEngineering] got a Model 3 Tesla Battery Pack and starts to take it apart. Unlike other Tesla batteries, and even more unlike Leaf or Prius packs, the Model 3 battery is extremely difficult to work with. As a cost-saving measure, it seems that Tesla found that gluing the individual cells together would be more affordable compared to other methods where the cells are more modular and usable. This means that to remove the individual cells without damaging them, several layers of glue and plastic must be removed before you can start hammering the cells out with a PEX wedge and a hammer. This method tends to be extremely time consuming.
If you only have a Model 3 battery lying down, [Kerry] it notes that it is possible to reuse the cells if you have time, but do not recommend it unless you really need the energy density found in these 21[ads1]700 cells. Apparently, they are not easy to find outside of Model 3 packs, and anyway it seems that using a battery from a Nissan Leaf can be a lot easier anyway.
