Well call this luck of the draw. I just had donated three 86 amp hour batteries and the charger that came out of a telephone communications tower. Probably will go pick them up next week. So till then, guess I don't get to use my amateur station as I robbed the power supply.
Thanks for the input from everyone who replied.
