Yep, I deflate it to stow it. The battery range depends on how fast you go, lower speeds = longer runtime and further distance.. hard to say exactly how many Nmi it can go but if I had to guess I'd say maybe 10 Nmi. At full throttle it has a runtime of an 1h20m, but going slower it lasts waaay longer. Battery weighs 20lbs, and detaches from the prop mount which is also 20lbs.

I absolutely love it, it's quiet, and it's surprising how different it feels to just go into neutral and coast, knowing it's not using power.. it's like a stealth powered kayak
