You have finally reached the helicopter! But your dreams of taking off into the skies have been dashed... the area is teeming with zombies! There must be at least a dozen of the undead brain eaters.

Without warning, all of the zombies run off into the woods. Something scared them off, but you cannot see or hear anything that would cause them to scatter like that. You shrug and attempt to start the helicopter. It seems to be battery powered, but missing a battery!

On the ground near the helicopter you find two large batteries, one labeled 'Low Internal Resistance' and one labeled 'High Internal Resistance'. Obviously you want as much power as you can get. Which one do you put in?
