IS this the best charger for <8 cell packs?

Hi all;

In my research I stumbled across a charger designed for the Remote Control modeling hobbyists. Here it is:

Is anyone using this to charge their packs? On paper it seems impressive, up to 20a charging, 1-8 cells, wide votage input range, and very configurable for different packs. Am I missing something that makes this unsuitable for larger packs, as long as the charge rate is acceptable? When large, I mean 10-60ah packs, which are much larger than the ones used in models.
