When it comes to electric vehicles, Tesla has always been at the forefront of innovation. But behind all that cutting-edge technology lies a crucial component: the battery pack. For models like the Model 3 and Y produced in China, these packs are made with LG NCM811 cells.

But here’s where it gets tricky. EV Clinic recently put some batteries to the test, focusing on those from LG assembled at Nanjing. The results weren’t exactly glowing. They found that out of 46 tested cells, a staggering fifteen had internal resistances over 100 mΩ—way above what you’d expect in healthy cells.

But why does this matter? Well, high resistance means the battery isn’t as efficient at storing and delivering energy. It’s like having an engine with too much friction—it just won’t run as smoothly or last as long. And to make matters worse, EV Clinic says that 90% of LG packs they’ve looked at can’t be effectively repaired.

Now, let’s compare this with Panasonic-produced batteries for US-made Teslas. They show a more gradual wear pattern over time and maintain better resistance levels. This means you might actually get to enjoy your car’s full potential longer. Plus, if something does go wrong, it can often be fixed without having to replace the whole pack.

In the end, while this news may raise some eyebrows, it’s important not to lose sight of how far electric vehicles have come in recent years. Whether your Tesla has a Panasonic or LG battery, there’s still much excitement ahead!
