I have a 30 x 30 barn that is a good ways from any electric. I am using lanterns and flashlights now but when I get some more animals I would like to be able to turn on some lights in the barn. I need a good informative website on what to buy, how to install and how to use 12 volt battery powered lighting and such. I have at least a dozen batteries that hold a charge well (from my uncles hovaround wheelchairs) and will be recharging them here at the house as needed. Thanks for any advice or extra info!
