Keeping your feeder working so that you do not ruin a hunting trip is key. So keep an eye on your feeder battery and solar panel. Label your battery with the date that you install it so you have a better idea how hold it is later down the road. The type of solar panels I use and found in this video are from Wildgame Innovations. As mentioned I am not particular to any brand. I just prefer the solar panels that have metal conduit like the ones in the video. Link to Solar Panel: www.academy.com
