More surprisingly after 300 100% DOD charge cycles at -10C at a 3C charge rate there was almost no loss in capacity. So occasionally charging at absurdly high rates at -10C (14F) has very little impact on your battery, and even doing it 600 times in a row is only slightly worse (25% capacity fade vs 15%) than room temperature charging. As I have been saying all along, the cold temperature charging of LiFePO4 is completely overblown.
Except that dendrites grow below those temperatures. What use is a battery I can't charge for weeks or even months at a time?
your going back to your "LiFePo4 is no good because I cant use it" several of us have said in your unique situation LiFeP04 would be a second choice for you because you wont take the steps to midacate cold weather use. so for you the Sio2 is a better battery, but you dont need to go tipping windmills because somthing that is right for 99% of the people isnt right for you..
