At the bottom end there is a very narrow strip. I think you could attach a small cardboard wall to it with a rubber band if you want to play half-blind chess. So that the piece is mainly only seen from one side. Hmm. Could be a try if you have fun with it.
@seeh_chess batteries aren't meant to be easily swapped on this, I haven't seen any latch on this for batteries replacement, the control unit (Black bar) may need to be dismantled. As for the battery life, it should last long if stored half charged.
