Getting ready to put my feeder out here in maryland to get ready for the bow opener on the 15th of sept my birthday and had a few questions. I bought the rechargeable 6 volt batterys and was wondering on a full charge how many days will it last until I have to change it out. The feeder I made is a 55 gallon plastic drum If I fill that up how long do you guys think it will last until I need more the feeder is set to go off in the morning and the evening. I am having trouble with squirells eating the plastic drum and lidany tips. I allready had to change the funnel and spinner to metal because they ate it and all the corn came out time to start squireel hunting. Last does anyone mix the corn and soy together were I hunt is surrounded by standing corn so I was trying to mix it up some just wanted to make shure it would work before I buy it. Thanks
