If this scales down to under a kilowatt-hour it means even a large ebike/scooter/etc. pack could move to double-digit US dollars in the next few years.
Most eBike batteries are half to 3/4ths a kilowatt hour, though if prices were lower you'd almost certainly see 1kwh & 2kwh batteries becoming standard.
The market is already headed this way, EM3ev keeps putting out larger and larger packs at the same price points year after year.
