Don't you also need some sort of battery controller to stop charging batteries once they are full?

  Nah, that's what "float" status is all about. There's a voltage where it's safe to let the battery sit indefinitely. Float is less than full-charge peak stress blow-things-up-if-you-stay-here voltage, but IMHO that's to be avoided anyway. So I set the power supply for float, not peak. Furthermore, all the lithiums have a built-in BMS that'll dehance the charge-path FETs if a single cell goes over its cutoff voltage. So even if my power supply were to lose its regulation and attempt to overcharge them, they'd just disconnect themselves. The lead-acids in such an overcharge state would simply convert more of their electrolyte to hydrogen gas and eventually deplete the liquid, but because the power supply is so weak in the first place, it couldn't force that to happen at a problematic rate. The regular drafts and air changes through the house would keep the hydrogen below its LEL unconditionally.
