    Yes, the 100% SOC plan sounds like the best solution.

    Mind your back though, they be much heavier!

    You may find that you are one red and one black interlink cable short.  Two of your son's three batteries will be inked together but the final one will have the long leads going to the inverter. You will need an interlink cable to put in its place to connect to your batteries.
    I had this problem when I got a secondhand set of batteries.  I solved the problem by using two Henley blocks to connect the two sets of output leads together.

    Access your system via the web page not app and there is an option near the bottom on the Maintenance tab - Battery Calibration Enable. Hopefully this will sort balancing the batteries for you.
