This post is intended as a reference point for others concerned with high ambient temperatures in batteries.
I have in my system 2 x 24volt 100Ah LiFePO4 Ampere Time batteries. Here in Tucson, the temps have been above 110F for 3+ weeks in a row now. My system, and the batteries, are in a 10 x 12 metal shed. Even with a tarp over it to shield it from direct sun, temperatures inside the shed have reached 130F. The Ampere Time manual gives the charge/discharge/storage temperature range as up to 50/60/50C, which is 122/140/122F . On the next page of the manual, however, it warns not to let the batteries get heated to 70C = 158F.
So, long story short, my system is operating apparently without a problem at the top end of its temperature range. It is not in constant or heavy use, but I do use it for relatively small things like LED lights in the shed and some power tools on a daily basis.
