Hi folks, Dale from NC (USA). Nerd engineer type working on a new project for my wife's greenhouse. It's small with only a few fans for the most part. Want to work on some solar power for it this year. I have an engineering background but I'll still ask a bunch of questions in the near future. Currentlylooking for a reasonable place to source 18650 cells. Anyone around Raleigh, NC speak up
