Motorcycle Batteries .. AGM, GEL, Wet, Lithium Iron Phosphate (LiFePO4)

Let's examine the most popular battery types, how to charge, advantages, disadvantages, etc.
In particular the new Lithium Iron Phosphate (LiFePO4) batteries. being fairly new not a lot of long term feedback exist yet.

Have been experimenting with li-ion cells for many years and was part of the original group on Candlepower Forums to adopt use of Li-ion cells. We were among world first users of individual li-ion cells. Several fires and explosions back then. A123 was barely getting started.

If you are in the market for a Li-ion motorcycle like I am... lots of questions to be answered. Are LiFePO4 motorcycle batteries with 18 Amp Hour rating and weigh 2lbs possible?

Are Lithium Iron Phosphate (LiFePO4) motorcycle batteries ready for prime time?
should I spend my hard earned $$$ for AGM, Gel, or std Wet Lead acid?

Hopefully we will answer these questions and more in this thread...

Note: this thread will constantly change as new information surfaces, errors corrected, etc. Apologies in advance for the technical mumbo jumbo that's unavoidable. Will do my best to simplify when possible.
