I BOLTR the 18V Makita 5Ah but first I'll show you why bigger is better. Because: CHEMISTRY! The small batteries have 5 cells connected in series. As such, the cells have higher current discharge ratings and generally lower Ah ratings. As a double whammy, higher discharge rates mean shorter lifetime. The larger packs have 3 parallel banks of 5 cells in series. That means each cell in the bank needs lower current discharge and has larger Ah ratings. More BEEF for Less BUCK.
