Help needed! 24v 7ah battery question

12V 16Ah Deep Cycle LiFePO4 Battery, 2000 Cycles Miady LFP16AH Rechargeable Battery.

Would 2 of these (thinking one in each compartment since they are slightly bigger) work far better than the factory 7ah batteries. It is true that 7ah to 15ah is just be longer-lasting power? I should not hurt anything with these? At $50 apiece, it seems two of these LiFePO4 Batteries make more sense than trying 4 cheaper batteries.

Looking for advice from the electrical specialist that has been on this string. Thanks!
