Lithium and DC-DC Charger?
My two group 27 lead acid batteries need replacing. Even though I'm too old to get maximum benefit from lithium longevity, I am thinking about going with a single 100 AH LifePO4 lithium. Doing some r...

Add the Precision Circuits LI-BIM along with the lithium battery. It is sold by Battle Born and others and serves to protect the lithium battery from overly aggressive alternator charging.
A single 100AH lead acid provides 50AH of charge capacity for whatever you are operating off 12VDC. A 100AH lithium battery provides up to 100AH of capacity or double that of the lead acid. My RV only has space for two Group 31 batteries and so I removed the two flooded ones and put in two Lithionics 125AH lithium phosphate batteries.
An unexpected bonus is that the lithium recharge to 100% SOC is less than a quarter the time of the flooded batteries. The solar panels and charge controller is also more effective as more charge can be applied while there is enough daylight.
