Charging my LiFeO4 batteries on my LV2424

[zack6736]

I have an MPP Solar LV2424 inverter with two batteries, bought two more batteries about a month ago and they have been sitting in the solar shed waiting to be hooked up. I have read all batteries should be close to same voltage when connected. My plan is: 1. Charge each 12v battery with my car charger to max voltage, then connect two in series and charge both 2 battery series again with my Lithium battery 24 volt charger, then finally connecting them up in series and parallel to my inverter. Is this the correct process or will I damage my batteries?
Thank you,
Zack

individually charge as 12V to full
parallel charge all 12V to full
Series them.
Confirm voltage is acceptable at peak 24V absorption voltage.
Check them regularly

Thank you. Have noticed on the two I have hooked up to the LV2424 only 3 bars showing up on the icon and inverter not charging until drops from there. Stated was at 26.3v on the screen of inverter.
