I'm not really sure which forum this should go under, but here goes. I do demos at some of the events I go to. I have a cumbersome kick wheel for demos. It comes apart to easily load. I was thinking it would be great to bring my little electric artista (easier on my body & lighter weight), but I do lots of outdoor events so no electric outlets. Anyone have experience with battery packs for running a kick wheel? Thoughts? Suggestions? Thanks!
