- April 1st, 2016Average rating1out of 5 stars1.0Great quality battery, doesn't include necessitiesMariusPhoenix | 19-24Purchased for: SelfI've already purchased three of the non-rechargeable battery packs (88000, and they work great!), but I wanted something that would be more convenient to recharge (So I don't have to remove it from my model each time to replace the batteries). Pros: - It did seem to come pre-charged, though I don't know how much - Definitely more powerful than the 88000 - The 7 phase power dial is really useful - It may be more expensive than the 88000, but in the long run it will be worth it as you won't need to purchase more AAA batteries Cons: - The LED's are in different spots from the 88000 (See pics), which make it annoying to see it's current status on sets - NO CHARGER (Continued below... ) I design custom trains for my collection and I'm always looking for ways to improve them, and this battery is a must for anyone who needs just that. (Continued:) I'd love to give the battery itself a full 10/10 as it stands tall with Lego's stamp of quality, but then a 0/10 for how poorly it was listed on this site, from the sheer lack of information, to the missing but simple necessity: a power supply. The description for the 8878 Battery made it sound like the power supply wasn't needed (Either included or was a common voltage), so I figured I'd have one at home or would be able to buy one locally and save money on shipping: that didn't work. The battery requires an odd voltage wall charger of 10v 700ma, which wasn't listed on this site... I didn't have one, no store locally had one, and the final annoyance with this whole ordeal, was on the instructions: as it ACTUALLY STATES "Only use an original LEGO transformer to recharge the battery"... I have never been more disappointed with a purchase from the Lego site in my entire life, I should have read the reviews... I would have still bought this item if it was $20 more and included the charger, now it will be twice that and more to order it... The entire product (8878) is essentially useless until you buy the wall charger for it, which is ALREADY overpriced for a wall charger. It's going to be a long while before I can order the wall charger, and all that time I won't even be able to use this expensive battery... I don't like writing negative reviews, believe me, I am writing this because I want Lego to improve, to do even better. I've been a builder my entire life and will continue to promote Lego as the best toy builder in the world!Play ExperienceAverage rating5out of 5 stars5.0Level of DifficultyAverage rating1out of 5 stars1.0Value for MoneyAverage rating4out of 5 stars4.0Building Experience: Expert LEGO builderWas this helpful?15LEGO® Power Functions Rechargeable Battery Box
- September 7th, 2018Average rating5out of 5 stars5.0add other plugs on top off motor.greenhornet003 | 35-44I would recommend this to a friend!Purchased for: SelfCan you add 8870 power functions Light V120 on top off power motor drive. I tried but the lights do not come on when I push the green button, the motor still works. Is cause the rechargerable battery box is not powerful enough? or needs a switch of some kind between the lights and the motor. Otherwise a great ideaSeptember 11, 2018Emily, Customer ServiceThanks for your review! The LEGO® Power Functions Rechargeable Battery Box features a speed control mechanism on the front. When used with the Power Functions Light, the speed control turns into a brightness control. So if your Battery Box is set to the lowest speed, the lights won't shine. Turn up the speed, and the lights will gradually become brighter. If that doesn't do the trick, then you can get in touch with our Customer Service team at LEGO.com/Service.Play ExperienceAverage rating4out of 5 stars4.0Level of DifficultyAverage rating1out of 5 stars1.0Value for MoneyAverage rating3out of 5 stars3.0Build Time: 10 minsBuilding Experience: Intermediate LEGO builderWas this helpful?55LEGO® Power Functions Rechargeable Battery Box
- November 4th, 2015Average rating4out of 5 stars4.0Good for long trainsBVG9Volt | 25-34I would recommend this to a friend!Purchased for: SelfI bought my 3th rechargeable battery box for one of my Lego trains. I prefer the rechargeable one above the AAA-battery box because the power is higher which is good for a long train. Otherwise you don't have to take out the battery box of the train each time to change the AAA-batteries. You have only leave a hole where can connect the DC-adapter. The price is high but it gives a lot of power and the train can run a long time.Play ExperienceAverage rating5out of 5 stars5.0Level of DifficultyAverage rating2out of 5 stars2.0Value for MoneyAverage rating4out of 5 stars4.0Build Time: 1 minsBuilding Experience: Advanced LEGO builderWas this helpful?45LEGO® Power Functions Rechargeable Battery Box
- November 14th, 2017Average rating1out of 5 stars1.0They don’t really work.....Vanhof | 35-44Purchased for: SonAfter charging I find that they won’t turn back on, sometimes they will sometimes they won’t. I bought 2 batteries and 1 charger at the same time and after 2 months they are pretty much garbage.... too bad my son loves his Lego trains but they are expensive to keep running
