Wiederaufladbarer Li-Polymer-Akku für mBot Roboter-Bausatz

Charging this up for about an hour gets my son's robot running for a solid afternoon of play, way better than constantly buying AAs. It clicks right into the battery slot with no fiddling, and I like that I can just plug it in instead of hunting for disposables.

Swapped out the AA batteries in my kid's robot and this little pack fits the compartment perfectly. We get a solid couple hours of play before it needs a top-up, which is plenty for one sitting.

Charging this thing takes about an hour and then my kid gets a solid afternoon of driving the robot around the living room. No more hunting for AA batteries every other day.
