I finally got the 1/4" thick steel compression plates and started work assembling my first (of 2) battery packs. This one is a 230AH LiFeP04. My other one will be a 560AH.

I just have to finish up my compression, add the BMS and I should be ready to charge this bad boy. I added some (unnecessary) labor to my assembly by using solid rod (as apposed to "ready threaded" rod). I also tapped holes in the back plated to thread the rods into. As shown in the picture, I have not yet cut to size and thread the spring end of the rods. I guess that I was just bored.... :-)

So far, (as best that I can recall) I have just around $850 in this one and the 560AH will cost about $1600 (totally different project). Thanks to Rick, This is about half what you would pay for a manufactured 200AH LiFeP04 battery. This one will have 15% more useable AH. It will be considerably safer and last considerably longer.
