I loved this! The battery pack for the UPS turned out to be three racks of seven ordinary "alarm" batteries all in series. That's 252 volts. Oh yeah... This is a two-sided battery pack. There's another twenty one batteries on the other side you can't see. I didn't bother to see if the two sides were in series or parallel. I just loved that they made this out of standard batteries.
