Upgrade to Lithium FE battery question
I currently have two Renogy AGM batteries, hooked to a Renogy PWM Solar Charge Controller and also charging from the converter. I just scored on a pair of LiTimes LiFEO4 batteries. Plan to instal...

I recommend that you consider a Victron Smart shunt to go along with those Lbatts. The 712 is the best. I did get the gauge too but the phone app for it is very good and you can do without. Then you can keep track of the AH in and out of the batteries and the voltage status along with state of charge. You did not say that your new Ltime batteries are 12vdc but I am assuming they are.
You did not tell us the model of your WFCO converter. If it is an older non Lbatt compat it might not give you the boost mode due to the higher at rest and the differences in the voltage of these Lbatts.
The Victron controller already have bluetooth and I can see how many watts are coming in and going out, battery voltage and solar voltage. Not sure what functionality a Shunt will add.
I mentioned below the converter is WFCO wf-8735-p. It's made before LiFeO4 days and it'll bulk charge at 14.4V. My LiTime manual says bulk charging voltage is 14.4. Only the absorption phase is where the WFCO convert falls short at 13.6V where the LiTime wants 14.4V for aborption as well. That's where I think the solar Victron will be able to top off the battery in absorption phase.
