Parallel 325 ah Trojan bank with 435 ah Trojan Bank: how bad is this idea?

To OP,
If I were you, I just go and buy 2 new 6volt 225AH golf cart battery and parallel them, and put them with other 7 to help to get few more years if lucky enough.
Cheers.

Thanks. After countless hours of equalizing these batteries and breathing way too much battery acid I got them where they needed to be and sold them. I'm going LifePO4 and will never look back (hopefully).
