The only graphs I can find say that SiO2 are at about 80% of capacity at -20 c (-4 f), and that LiFePo4 are about the same.

Of course if we drop down another 10 degrees to -30c (-22 f) then SiO2 are at 60% and LiFePo4 there is no graph I can find.

the graph on azmuth solar shows that at -20 the SiO2 is about 75% and different graphs I have looked at show the LiFePo4 at about 80% so not a lot of difference and on a small battery we are talking a small amount. but it also gets compounded when you can only use 80% of the capacity on the SIo2. not a hughe deal like I said just another comparason, still way better than a lead acid.
