Two improvements
There seem to be two improvements at work here: One is making the batteries hexagonal, thus eliminating most of the wasted space between each battery element, which is about 10% or more with traditional cylindrical elements. The other is a reduction of the losses in the accompanying electronics for charging and load-levelling purposes.
How these improvements can result in a hundred-fold improvement without changes in chemistry and such is quite baffling — maybe there is some cold fusion involved too?
