This looks like some sort of serious piece of equipment of what variety I do not know. If anybody can tell me what this is I would appreciate it. It is sold as is. Please see photographs as they are part of the description. I have attempted to list one of the number sets from the capacitors i can see and can try to provide further information if anyone is curious. Could be this is simply an old-fashioned battery charge pack? All the electronics from this lot purchase appear to be well cared for and working. Please see the positive feedback.
