Hi all, I'm designing a chicken coop and I want to have a water heater and automated door for it. I don't really want to run an extension cord from my house to the coop (as it's quite far), but I want to have this powered appropriately. Do you have any recommendations for batteries that I could buy that can run this coop for an extended period of time? I was also thinking of buying a solar panel and have it top off this battery as needed. I'm not too familiar with the electricity aspect of this all so all suggestions are welcome! Thank you!
