if so how would i go about wiring them? i think it would be cool to have two and be able to have them charge everything and be able to work together or with only one if one goes out. am i dreaming or can this be done? could you run them through some kind of voltage regulator so that the two only put out 12 volts? or you could have dual batteries as well and have one charge each. then use an isolatore so you could swich to one or the other if one went out.
