Very late on this, sorry.
I'm curious to see if you expect to get 7 years life on a LiFePO4 in hot states. I just measured the battery temp (at the terminal) on my truck, it was 163 ºF. Road surface temp is 155 ºF.
This is quite common, everyday summer stuff here in Texas.
It seems very unlikely that you can hold a LiFePO4 at 100% state of charge in a temperature environment like this and still get anywhere near 7 years of life.
Are you doing something like using a 20 A-H battery, charged to 70% SOC or something, to deal with high-heat/high SOC degradation?
