"Tesla Motors announced that current Roadster owners (~2,500 of them) could now swap out their old batteries (53 kWh) for new ones with improved technology providing 70 kWh of power."
"The original Roadster battery was the very first lithium ion battery put into production in any vehicle. It was state of the art in 2008, but cell technology has improved substantially since then. We have identified a new cell that has 31% more energy than the original Roadster cell. Using this new cell we have created a battery pack that delivers roughly 70kWh in the same package as the original battery."

Would be nice if we could _officially_ upgrade our batteries to a bigger pack.
Although the increase wouldn't be as big since our pack already uses bigger 16550's right ?
