Hi all, and thanks in advance for any help. My situation is that I'm building a battery bank for my new solar system. I want my system to run on 24v. I have purchased six batteries in total - all of them are LifoPo4 Zooms/Redodo - all of the will be charged with a victron 150/60 charge controller. Four of them are 12v 200AH, two of them are 12v 100AH. My first question is - should I return the two smaller batteries? I bought them bc we didnt have enough money budgeted to by two additional 200Ah batts, so we bought two 100Ah. I realize now this isnt ideal. Any advice to move forward?
My second question is regarding wiring the bank. I understand I need to wire in a combination of parallel and series, however I am getting differing opinions on how to go about this. Here are pictures of a few options I am considering. Any advice is appreciated.
This is the arrangement the redodo manual suggests:

The circled section is what seems to be the most common way I can find on the internet to solve this issue, but others point out potential balancing issus:
