How is this for a power system? Solar vs battery balance?

LA, based on your other posts, location, cold weather use, I'd think real hard about dropping the coin for Lifepo4 batteries.
Aren't they going to steuggle big time with the cold?
Have never used a lithium battery in the cold except for cell phones, which the lack of performance in the cold is evident.
I'll have an into this year with a snomachine with a lithium battery. Will see how it works since it typically is not extremely cold where I ride.
I'll have a fresh jump start pack in my bag for sure!
