I guess it depends on the charger then. My Pro Mariner 60-12 can do 3 banks at 12v in any combination up to a total of 60amps. If I was buying a charger rated for 20 amps I would ensure that it provided 20ams on a single channel. The only real reason to have more than one channel is for banks with different chemistrys. If same chemistry then you're gonna want a combiner like an ACR anyway so that you alternator can charge both.
