Lithium Iron Batteries and Charging Systems

Depends on who you ask. I have a fairly new PD9245 model converter charger in my 2018 Navion that was designed to support the 2 cheap FLA dual purpose batteries that came with the motorhome. It has no LiFePO4 specific charge profile. I replaced the OEM batteries after a year with 2 X 100Ah Relion LT Series lithium iron phosphate batteries, and added a PD Charge Wizard Pendant to the PD9245, so I could boost the charging rate above 14V when plugged in to shore power. Otherwise they're charged by the 220A Bosch alternator, or the 300W of Zamp solar up top, using a LiFePO4 charge profile in the ZS-30A charge controller. So far, no ill effects from this set up, that I have noticed over the last 2 years. I also don't micro-manage my batteries, I pretty much trust them to do the job when needed, and so far they have done that. They may charge more slowly, or not to 100% every time, but I (and they) can live with that. They will also charge down to 4F/-20C by using some of the charging amperage to self heat, which is one of the reasons I chose them over the other options. I live in the GWN.
Don't know if this answers your question?
