Daily Charging when not in use?

[NotToFast]

Ok, I have one lonely little 100ah LiFePo4 in my tiny camper with 200wats on the roof tilted towards the south. (I'm in NC). The battery has no parasitic draws that I can tell, and everytime I check it it is at 100%. The question is: Will the daily application of solar charge to the battery shorten its life? Is it Ok to keep it at 100% charge for 6months or more? In summer I run the Roof top fan to keep from roasting the spiders taking refuge in the camper when I'm not using it. The lowest it went this summer was 72% during a week of cloudy weather. But during the winter it just sits and charges as it can. (It does have low temp cutoff) Thanks

You should be fine if you aren't keeping it charged above 13.6V.
