Has the power of batteries come a long way from the past? I have an 18V black and decker that I have to fight with to drill/drive into a pressure treated deck, and that’s on a full charge; the power just isn’t there. I see 12v here, and there was, I think, drill/driver around 7 or 8v at some point.
So the question is, are today’s 12v more powerful than those of yore, or are they the same, and this set would be intended for light projects?

No, and maybe. 12v is 12v anywhere you go, and the amount of voltage supplied to the motor dictates how much power it can put out, and therefore how much force is used to turn (and then strip, and then yell at) the screw/bolt/whatever you’re working on. 12v is, at least in my DIY’er research, the bottom rung of heavier duty power tools for harder projects, and you won’t be able to do things with a 12v drill that you can do with, say, a 20v. I know that’s a nebulous statement, so here’s an example from some work that I just did on the house. Let’s say you’re hanging some drywall, and you’re trying to put long drywall screws into the 2x4’s to secure it in place. For a 12v drill, you’re probably only going to get a 1 1/4in, or maybe a 1 1/2in screw in place before the force of the screw compression in the wood overwhelms the 12v drill motor and the drill stops. The 20V drill, by comparison, will be able to put in a 2in or 2 1/2in screw no problem, because the motor has enough power to do so.
There are ways to compensate for this, such as pre-drilling holes, but if you’re doing a project where that’s time prohibitive, such as building a deck or hanging drywall, it becomes a massive chore and you’d be much better served buying the right tool to begin with.
As far as the charge goes, these things will last and last. I just used my friend’s Craftsman lithium, and that thing went for the entire time we were doing garage drywall and then some. I’d expect this to be no different.
