If it can be done, then do it! Someone here posted before, that he wanted to get off the grid, you can find his post and ask if he succeeded. Since I havent seen anymore post from him, I assume that he is still on the grid, or in the forest with dead batteries. I just hate to be out in the boonies and have dead batteries. Rechargeable dont even seem to last very long, but are acceptable if you can get a good charge every night, but would hate to rely on the sun for my hunting.
