I did the Jager Box external 6volt battery setup and added a solar charger. I put it out in June, and the battery just finally died, because my pics went from 5 a day to 50 a day, which are mostly at night. Fall food plot is the reason. Its funny because during the day, the solar panel will run the camera. Even though the external battery is dead, the camera turns back on once the sun comes out. But once the night time hits, and tries to take a pic, it dies. I have to go up this weekend and swap in a new 6v battery, or recharge the one that I have in there. I do not have any batteries inside the camera itself.
