It fit perfect. It does protrude a little more than the standard batter compartment. Has already saved me and my children from having to break apart a couple of designs. I see long term value. And it lasts. Longer than any (even high drain digital device) batteries anyway.","review_amount":"12","rating_original":"4.0","rating_converted":"80.00","author_name":null,"embed":null},{"review_url":"http:\/\/click.linksynergy.com\/deeplink?id=TZZm7nNaZzs&mid=13923&murl=https%3A%2F%2Fwww.lego.com%2Fen-US%2Fproduct%2F45501","snippet":"No need to buy the expensive charger! I have successfully used both a 9 volt and a 12 volt power supply to recharge the battery. My research indicated that the battery pack contains an MP26123 monolithic DC-DC stepdown switching charger, so the exact voltage is not critical. Nine and twelve volt power bricks are very easy to find, and are also inexpensive. I wouldn't recommend going below 9 or above 12 volts.","review_amount":"10","rating_original":"3.6","rating_converted":"72.00","author_name":null,"embed":null}]}
