"But the team is making extraordinary claims about charging, saying the Mark Zero is capable of blast-charging from 0 to 80 percent of its full capacity in 4 minutes and 40 seconds. The battery is built by Desten Group, Limited <http://www.desten.com/>, a Chinese/German operation based in Hong Kong.
Desten is cagey with details about its batteries, but claims "exceptionally high charge rates, 10C or higher," as well as power density in excess of 1600 watts per kilogram. The company says its cells can be fast charged and discharged 5,000 times before they drop to a capacity of 80 percent, suggesting excellent longevity particularly if the cars are charged slowly overnight most of the time." Definitely not a mistake... who knows whether or not they can actually do it, but there appears to be a few different companies claiming they're making batteries that can handle 10C charge rates. I think they're just using the battery manufacturer's charging claims, and not actually expecting to be able to charge a real car that fast.
