>He took Zero Motorcycles from a battery pack that only went 40 miles to one that goes 120 miles while making the battery pack physically smaller.
And what did he actually do? lithium ION batteries have been increasing in capacity over the years and quite considerably, 18650's are now nearly 4 times the capacity they were introduced in.
I can't find anything he actually did other than hack batteries together to make "custom" packs, while this is some sort of an engineering achievement this is quite far from designing an actual battery.
Those "packs" are batteries. The thing that he did not design are electrochemical cells. The term battery pack is a misnomer invented by people who do not understand the difference between a battery and an electrochemical cell.
