How to build a LiFePo4 battery bank.

There's a guy over on DIYsolarfoum who is selling a bunch of 700AH Winston batteries his company bought and then realized weren't right for their project and now they're trying to get them off the books. I'd buy 4 if I had room in my battery compartment and sell my current 271ah pack. These batteries can charge well below freezing.

I have no financial interest in these cells or DIYSolarForum. I just hope someone is able to take advantage of a good deal.
