Whatever you wire in series makes up a string. Therefore, if you use 12V batteries, you can’t wire 2 in series because you’d have 24V, etc. You are therefore limited to 1 X 12V battery being a string.

Likewise, 2 X 6V batteries wired in series makes up a string. And 6 X 2V batteries wired in series also makes up a 12-Volt string.

In a Golf Cart they typically wire 8 X 6-Volt batteries to make a single 48V string.

In doing research, I found most battery “experts” recommend not exceeding 2 strings in parallel. So while it’s possible to wire 4 X 12V batteries all in parallel, it’s not ideal. For example, if one battery goes bad, how would you even know?

One string is simplest, but doesn’t provide redundancy. Two strings is a middle ground. Three or more gets complicated, etc. Anything can work, it’s just about best practices.
