glad ta know you== ya just saved me lots of money in battery costs-i schooled in microprocessers/microcomputers and motown is not far off with his tractor battery but a 6 volt battery can be hard locate and normally cost more---but a 12volt battery with a resistor to knock the volts down to 6 and use the heat generated by the resistor to warm the battery so it can charge from the solar panel is flippin brillant
if ya got any wind use a wind generater
way ta use your noodle dude
