Larry,
See the thread below for more info on my bank. At this time I am not really recommending DIY home builds of LiFePO4 packs. I am getting my hands into it so I have a full understanding of the technology, as it comes up to speed and so I can stay ahead of the curve.
I just came back from doing a Genasun install in Puerto Rico that is a 1080Ah 24V house bank and 360Ah electronics bank. The pre-made stuff is much simpler but also very expensive. Genasun builds a hell of a product.
