There are cheaper ways to repair it outside Tesla:

  Tesla tried to charge $22,500 for new battery pack when a $5,000 repair did the trick

  While Tesla recently started opening up some of its diagnostic tools to third parties, the automaker still has a lot of limitations when it comes to powertrain diagnostics. Electrified Garage uses some hacks to get past that and figure out what is wrong with the pack. In this case, they detected some voltage imbalances in 2 of the 16 battery modules:


  So how much did it cost? The modules were $1,500 each, for a total of $3,000. Another $750 in parts for contractors and fuses, with the main one being upgraded to the ones introduced in the Model S Ludicrous.

  With diagnostic and labor, it came up to about $5,000, or about 75% less than Tesla was quoting for a full battery pack replacement.

I'm more curious how much money he made off the youtube video. If it was anywhere close to $5K, it would seem that maybe exploding Teslas at their end of life would become a profitable thing to do.
