You are correct that A123 is a brand name, but the A123 will also out preform a standard LiFe battery every time. That is why when this the nano technology was developed at MIT, they got a patent on it.
On standard LiFe batteries, the molecules on the negative plate are all end to end. On the A123 all of the molecules stand up on end like a shag carpet giving the plate more surface area allowing these cells to charge faster, discharge faster, and the negative plate of the battery outlasts standard LiFE batteries, thus a longer life and more recharges.

Correct!
A diode will not drop voltage, it will only prevent you from reversing the polarity. A resister drops the voltage.
A voltage regulator is needed.

Sorry thats not correct.
