Yes keep the charge rate under .5 because it can actually charge that fast unlike lead-acid.
I thought fast charge was good?
Yes the LFP needs to stay above freezing or the BMS will automatically shut it down to protect. Unlike lead-acid that goes ahead and freezes and is wrecked. Heater or warm compartment works fine.
Yea don't cycle below 15% because with lead-acid the discharge should stop at 50% or even sooner.
Yes no need to float the LFP. That is a feature. Lead-acid starts to sulfate.
Once the charging system is set properly there is no 100% float and maybe just charge to 97%. Unlike Lead-acid where top voltage needs to be applied for a few hours at 100% or that sulfating thing is setting in again.
Just turn the generator off a couple hours early because 80% 90% 97% whatever random charge is just fine.
And when the RV gets home no need to top charge, equalize or water the cells.
Peukert induced lower capacity in lead-acid virtually does not exist For LFP.
The higher operating voltage gives about 10% more watt-hours of energy for the same amp/hour rating.
The reduced voltage sag will not have the inverter shutting down prematurely.
Get a smart LFP and the charge level can be read on the phone app along with discharge or charge rate, temperature etc.
