white paper on SiO2 batteries
Hi, Finally found one. It compares Lead Acid, Nickel Based, Lead Crystal and Lithium Based Batteries chemistries. https://azimuthsolar.ca/wp-content/uploads/2020/08/study-of-comparison-of-charac...

yup it is if you camp below -17ish or consistant daytime highs below 0 longer than the capacity of your battery. but cost wise isn't the reason. I just priced out SI02 batteries here and to get the same capacity (usable) it is slightly more with SI02 (maybe thats the special BC price) if I do the rool my own (which it looks like I am) then SI02 becomes over 2 to 3 times the price for the same usable AH.
I would also argue that if your willing to move your batteries into the living space (LFP have zero off gasing and can be mounted in any orentation) that you can camp at -40. but anything below -20C would require a heating pad to prewarm the batteries to -20 before starting the furnace, but once the furnace is going now issues.
