I fitted a LiFe battery to UFI, I found that the high parasitic draw of a modern car will kill a LiFe battery very quickly if you're not careful (due to relatively low reserve capacity - I had 14Ah). Many new cars with electric everything are lucky to get three years out of a lead acid battery, my Pb battery only lasted about nine months from new, and the LiFe only went two tanks
LiFe batteries can also cause new cars to have electical gremlins due to the change in voltage, charge acceptance etc. My car had all sorts of issues and I finally resigned myself to the old Pb tech.
Even fitting a Supercap to the Pb battery on my low tech Renault caused issue.
