Ryan,
There are some subtle things about tying batteries in parallel.
If you are building your bank from basic cells, with large conductors, that's one thing.
If you're using 48V battery systems with built in BMS's, that may or may not work.
In any event, you have to be sure you have thick enough cables running everywhere.
In that regard, parallel batteries are easier to use for extending range than increasing the max amperage (for shorter periods of time).
Technically, in theory - you can either increase the max load or increase the range by adding more batteries in parallel. Just be careful. The hard part with parallel systems is ensuring that the power is being equally drawn from all systems, and then that all systems equally charge at the same time/rate/voltage.
Good luck!
John

Ok, I adjusted my googling terms and was able to answer my own question, yes in parallel the max draw will increase. Sorry for the super basic question. Was one of moments of second guessing myself after having figured this out once previously and then the doubt turns to imposter syndrome and well, you get the idea.
