Multi Battery Charger for Lead Acid



I have a 0 - 15V, 30 amp power supply that I want to use to charge several small SLA batteries at the same time. The problem is the batteries are slightly different capacities and will be at various stages of discharge. What I want to do is have some way of limiting the current going to each battery to about 2 amps. What is the easiest way to do this?

Note, I want to get a minimum of 14V to the batteries, so whatever circuit I use needs to drop no more than 1 volt, preferably less.

I have searched Mouser and Digikey for current regulators but haven't found anything that looks like it will do the job. Obviously I don't know exactly what to look for.
