How to remove trunk floor at the Junkyard?

Buy some extra batteries. I have a bunch of 20v dewalt cordless tools, and I could remove a trunk floor with a spot weld cutter and a well charged battery. I'd bring a couple extra because I have them but it would probably only take one if it was fully charged to start. It would probably take 2 or 3 spot weld cutters and one battery. Not sure a sawzall would be any better for a trunk pan. Might be a little faster but it would probably chew up a couple blades and the same battery with an extra or two in reserve. I'm amazed how long the charge on those 20v tools goes, battery tech has come a long way even in just the last couple years.
