What is the reasoning behind 48V?
Most countries distinguish between “low voltage” (LV) and “extra low voltage” (ELV). LV would typically be 120V or 230V house mains, and is dangerous to touch. ELV is generally safe to touch. The line between the two is usually set at about 50V.
So 48V is the highest battery voltage that's safe enough to touch, so requires much lower standards of insulation.
