Lithium Batteries
Just downsized from a Class A DP to a Class B+. I got the residential fridge in the new motorhome so power when off the grid is going to be more of an issue that it was before. I’ve been looking at ...

3 tons,
I'm wondering about your last sentence above.
Doesn't your 9245 automatically drop back to a 13.XX volt float voltage at some point when it's charging batteries?
I believe that LiFePo4 batteries have a recommended float voltage such that they can be left hooked up full time to a converter/charger that eventually settles at their float voltage, just like any other type of battery.
For instance Battle Born LiFePo4 batteries can be floated at 13.6 volts or lower indefinitely according to their specifications, so you shouldn't have to disconnect them from your 9245 when it drops down to it's float voltage.
As for when driving with the engine alternator hooked up to the batteries, after just a few minutes when things are warmed up, our RV's alternator settles in around to the mid-13's in voltage, anyway.
True with the 9245!....(except for the 21hr/15 min equalization cycle)...This is why I prefer the standard charger (with charge wizard in boost mode) to PD’s LiFePo4 offering, but once the battery has charged (and subsequently finished it’s BMS dance whereby current and voltage values briefly alternate..), I simply disconnect the battery (via basic knob switch atop battery post)...I mostly dry camp, so rely on solar and battery...
