How Lithium Polymer Batteries are Made
The final stop on the tour was is a room far from the others, on the opposite end of the building.
This is where the very large battery packs are built and tested. I was told these are used to power an electric bus.
Imagine what you could do with 49V at 40,000mAh. The largest packs were 100Ah. That's nearly 5000Wh! Incredible stuff.
