Alright so I have these two things which I figure there must be some good use for, both from battery backup systems. First is a nice, chunky 15lb transformer. Two wires on one side four on the other. I can't find anything searching the numbers on it, so am wondering what I can do with it. I do know that the white and black wires (ont he side with just those two) are not mains input, I tripped the breakers like that lol.

Next is this board with these massive, toroid rings? (my best guess). it has two spade connections on each side, and those are connected through those rings. Each side has all 3 hooked up connecting the two rings together, I have provided a scan of the bottom of the board. These rings only have one wire each.
So, what is this board for and what is something I could use it for?
