It better pump water out of the battery for $4,000 for the US version. I think I'll just buy a kayak ($600) and an electric trolling motor ($200) and spend the rest on booze and something worthwhile
Riding that thing for _40-50 minutes continous under power_ is gonna be an olympic athlete level workout. If that's you, you should be making enough money doing it to have no iasue buying a stack of extra/spare fuel cells.
That‘s a new technology - you can reload the battery by cooling it off with water. Every time it goes empty - just get it wet and cold and you are good to go again.
Every time I see this demo, they splash water all over the battery before putting the cover on. Not sure if they’re cooling it off or demonstrating it’s waterproof.
