PF - Its a bit hard to figure if your post in "tongue in cheek" or not.
The battery in my folding electric bike is an overgrown sealed Ni-Hydride unit like the one in my computer.
I guess as I am the Captain, I can consider myself to be appropriately notified!
If anyone is interested, the electric folding bike is a Sherpa Mk3. Weighs 21 kg, incl battery. I took it for a lap yesterday. Sits on 25 km/hr on the flat, running on just the lekky motor (I am 90+ kg). If I give it a bit on a helping hand by peddling it will run up over 30 km/hr. Has a range of 30 km on battery power only - more if you peddle a bit. I am pretty impressed with it.
Why did I get an electric folding bike? Cause I am fed up with places like Cairns and Rocky where I am forced to park the Bo on the opposite side on the field from the airline terminal and then have to get a taxi to and from the terminal to collect and return a rental car.
