The Tesla Roadster started the Electric Vehicle rEVolution. And now, 15+ years later, the main batteries may finally be starting to die. The original Tesla main battery design engineers were targeting a 10 year service life as cars were being released in 2008. We were all pleasantly surprised to find the majority of Roadsters still driving and functioning. In today's video we delve into an alarming trend we are beginning to see in the main battery pack, related to not the original packs released in 2008, but a replacement pack released in 2016, designed to extend the range and life of the packs. It seems 2016 upgraded Roadsters are beginning to suffer from a loss of power eventually so severe, it renders the car undriveable. We believe this may be early indications of an end of life failure mode, and a possible predictor of similar main battery demise in the next generation Teslas, the Model S, which also uses 18650 cells. ----------------------------------------------------------------------------------------------------------------------------------------------- You can also check us out on our Patreon, Facebook, Instagram, and TikTok pages below.
