That NAPA battery is described on some websites as "excellent for starting and moderate deep cycle use" - nowhere near the kind of battery suitable for a golf cart's demand for power. If I understand his wiring description correctly - the two middle batteries are the weakest link- they are not being "helped" in parallel - so the current demand called upon to go up a hill is basically being pulled from them (their power will collapse first). The 48v setup described is fine for testing low loads and general cart operation - but its way too anemic to provide the amperage reserve for a hill climbing test.

There might be something else wrong with the cart - but until sufficent current is made available - we'll never really know.
