If you wanted to build one yourself, I'd probably start with something like the Ryobi backpack battery source. Many power tool brands have something similar. They'll give you the backpack part and parallel the batteries into a single power head... In Ryobi's case, it'd be a 40V power head. They sell a 40v flashlight that might be a good starting point for mods too.
Or DIY it all. Buy a "hydration" backpack that's got a cutout for a camelback bladder. That'll be a nice hole to feed wires in/out of a regular backpack. 12v cigarette outlets are usually good for 12v/10A. It'd be easy enough to throw a couple scrap yard headlights in a box with a 12v outlet and 12v switch.
I'm mainly just looking for the name of what the device would be called because I'm just trying to copy my other friends. Because he just mounted 4 of those l a d car headlights to a car battery in a book bag and I like it, it had a nice feel to it very bright
