So, basicly I am looking for a way to get A LOT of energy on the road. I am looking to power some big speakers, my laptop and some other mixing equipment. I want to be able to do that for some good 6 hours at least.Now, without getting to specific on my power requirements, what would be the way to go to get an extension chord (with multiple sockets of course) powered.My idea was this:Buy some car batteries, somehow combine them and then use that to power the cable.Now my question would be about the "combining" part as well as the part where I use them to power the extension chord.In what way shape or form can I use 5 batteries to power one cable. (The absolute best solution would be a smart board or something similiar that would use one battery after the other in sequence)If thats not possible then why not have it use all at once. Anyway, Im not exactly the most technical person so any help is greatly appreciated. via /r/DIY http://ift.tt/2rDf1Pg
