This is a weird article saying the batteries were long in the tooth. The Model S and Model X both had their electronics upgraded: https://www.teslarati.com/te

  I thought the range upgrade was the Model 3 motor, not the Model 3 battery tech. Tesla is sitting on two upgrades for the Model S battery wise: 2170 cells, and improved chemistry. The Model S would have a 600+ mile pack with those two techs combined, which is probably where the Roadster 620 mile range came from. Not sure if this includes the improvements from the maxwell technologies acquisition, or the Model 3 motor efficiency gain.
