You'll get a 400 ah 12 volt bank with 200 ah useable.

Yes. this.

Ah is voltage dependent

Ah in series doesn't add. Voltage does.

Ah in parallel adds. Voltage does not.

to make 12V, it takes two in series, so now you have a 12V 200Ah battery.

Parallel another two in series with the first pair, and you have 400Ah.

4 in parallel gives 800ah @ 6 volts. 4800 watt hours or 4.8 kwh.

4 in series gives 200 ah @ 24 volts. 4800 watt hours or 4.8 kwh.

2s2p gives 400 ah @ 12 volts. 4800 watt hours or 4.8 kwh.

See how that works? You still have the same amount of power, regardless how you configure them.

If you have 6V 200Ah, that's 6 * 200 = 1200Wh of storage. It doesn't matter how you arrange them. Each 6V will add 1200Wh of storage.

If you put 4 in series for 24V, that's still 4 * 1200Wh = 4800Wh of storage. If you want to know Ah, divide by voltage, 4800Wh / 24V = 200Ah.

I had eluded to it a couple posts ago.
