You will never get a 100% charge without a DC-DC charger.

Why would you need or want a 100% charge (14.6v) to begin with? Unlike lead-cell batteries, lifepo4's subjected to 100% SOC (14.6v) on a constant, short-term basis experience reduced cycle life. 13.6v will still net 99% SOC (and a higher cycle life), although at a slower charge rate.

Long-term float at =>14.6v can permanently damage a lifepo4. If you're the set-it and forget-it type, a 14.6v single-stage "lithium approved" converter/charger is the worst thing you can use to charge a lifepo4.
