Has anyone tried a LiFePO4 battery such as the Shorai brand that can
be seen at:

Weight of the 12v 14ah LiFePO4 battery is 1.6 lb vs 13 lb for a sealed
lead acid battery. And, it's smaller.

I think you would be very disappointed in the amphour capacity of the
battery. From their website:

"The internal "completely discharged" capacity of a Shorai battery is
1/3 the rated "PbEq" capacity"

So the battery has only 14/3 = 4.7 amphours with a full discharge. They
are offering it as *starter* battery, and the "PbEq" (lead-acid
equivalent) rating indicates it will perform that task as well as
lead-acid battery with that amphour rating.

But it sure looked good at first...
