Growing up in the 90's my parents loved rechargeable batteries for a while,
every time I turned around I had something with a Panasonic NiCad in it.
Later in the 90's my grandmother gave me her Panasonic NiCads and her
charger.  This was after my parents stopped using their's.  I ...

This seems too good to be true.  Do they work well?

Assume that we have four 12 Volt 20 AH batteries that are series
connected.
Is it possible to AUTOMATICALLY charge the 48 Volt string with only a
single 12 Volt Charger?

When seperating H and O from H2O electricaly:
A)   Is there a minimum required voltage?
B)   Can the current be stopped/started cyclicly?
c)   Does pressure hinder/enhance the process?

I'm a mad scientist and I invented a deadly railgun that can shoot
trough solid steel ! But it needs a lot of power, so I need powerful
fuel cells to make it the perfect weapon of doom.
What do I need ?

Anyone have a line on thin, small Li-PO cells?
Capacity is secondary, I need to power a load at roughly 80mA for 1-2 hours,
whatever I can get, but the thickness of the cell is critical.

Is anyone aware of any moderate capacity cells, (100-200MAH) in 2mm or less
thickness?
