To open Battery pack: Carefully grind or mill the top (connector face) along one of the long edges. The plastic is thin, so you only need to take out a little (<1mm). Alternatively, use a dremel tool preferably in a drill stand, so it acts like a mill, by sliding battery along a wooden edge (acts as a guide) under a small mill cutter. This also enables you to remove the corner neatly. This ensures batteries are not damaged. After removing one edge, pry up top cover with a small screwdriver. Although glued you should be able to pop it off without breaking it.
