I just saw that Stihl and Husqvarana make a backpack batteries. I have never used one. How well would something like this work out for powering a portable spotlight? Are there lots of different backpack batteries being made? I am thinking that lithium ion should make them reasonably light weight, but the cost may still be prohibitive for many people.
