Correct battery capacity for BMV-712 Smart initial setup

My system includes a Victron BMV-712 Smart voltage monitor and four 225AH 6V batteries in series/parallel so as to provide 12V to the Victron SmartSolar MPPT 150/100 controller. The initial setup for the BMV-712 asked for battery capacity but I was unsure at this point what value to include.

  • Should that have been 225AH like I input earlier? (I'm guessing that this is wrong.)
  • Should it be 225 * 2 = 450AH?
  • Should it be 225 * 4 = 900AH?

More specs on the batteries...

It will be 450AH, as 2 will be in series to increase the voltage, and 2 will be in parallel to increase the amp hours
