The temp sensor and tx board will be mounted on a pole in the middle of my back yard ~90 feet from my house. I'd just run an outdoor extension cord but mowing around cords is a pain in the rear. I have 2 AGM batteries I sourced from my Dad's electric wheelchair so I'll go with those until they die then I'll get a new one. Wife is already asking too many questions with the thousand little charges here and there for bits.
What do you think of this charge controller? http://www.diysolarforu.com/uploads/7/9/...roller.pdf
