Any battery gurus know if 3 pairs in parallel are better worse than 2 series sets of 3 in parallel?

I’d love to hear from some of the electrical guys if there is any difference.

Mostly I've read about 6V batteries in 12V pairs, and then those pairs being paralleled to make a larger 12V system.

But...

I've also read about 48V systems made up of eight 6V batteries in series, so I'd guess stringing a boatload of 6V batteries together is common.

But...

I've also read that it's not great to parallel more than 3-4 batteries at a time. Dunno if that's gospel, or if so, why...

But that might lead to why I've more commonly read about 6V series pairs being paralleled. In Ron's situation, that'd be three pairs of 125-Ah 6V batteries series wired to 12V, those three pairs being paralleled to a 675-Ah bank.

If it's better that way, I dunno why...
