I assume you would buy an existing battery monitoring system and just hook it up yourself to the cells ... yes, that's within range of some people.
JimH, one nice advantage of Liion is that their capacity stays up in cold. So, you can run the furnace and not kill the batteries, of course wanting to keep the batteries themselves above freezing. (which you can do when a battery provides decent amp-hour capacity in cold!
OP, If you want to geek out on some of the actual IC technology used in the BMS ... simply google "lithium ion battery monitor ic" and look for trusted IC manufacturers like TI, Maxim, Analog devices, Intersil. Plenty of white papers and interesting info. Poke around and you'll find datasheets, application notes, white papers, etc. You can even order demo boards of some parts and play around with smaller cells.
