Wire the 2 series strings in parallel by connecting positive to positive and negative to negative. If you want, check the voltage of your finished battery bank with a multimeter. I wired two 24V 100Ah battery banks in parallel to get a 24V 200Ah battery bank, so I expect a voltage of around 24 volts. I got 26.4 volts, which is exactly as expected.
