  EV3 battery

  A fraction on the expensive side, but in the long run worth it. There is an annoying feature in the EV3Mindstorms sets, the ease of changing batteries in built models / robots. In a lot of cases you need to dismantle part of the model to change the batteries and in some cases this can be difficult and includes unplugging sensor cables around parts. The rechargeable battery helps with this problem, but is not the whole solution because in accessing the recharge socket you can still need to pull out sensor cables or move a part to get at the battery socket. Perhaps a right angle power plug on the recharging transformer cable would help in most cases. Alternatively a short adapter cable approx 2 inches long that stays in place on the rechargeable battery, (optional feature ), that way it would be a simple matter to plug in the recharging cable from the transformer without trying to get around the robots cables and parts. Plug and socket extension cable would remain on a robot where it is difficult to access the battery recharging socket due to the robots compact and complex construction.

  Expected better from Lego

  Really disappointed with this purchase, for the cost I would have expected it to at least come with a power cord. Granted looking back at the description it does say it required the charging cable sold separately but really it seems a bit ridiculous to sell the battery pack without the charger. So in reality the chargeable DC battery pack costs more than what is listed. So now I'll need to order the charging cable and wait for it to arrive before I can use the battery pack. I expect better from Lego.

  It is a little bit expensive but very good product. I used rechargeable energize batteries and I could only play with the EV3 for 20 minutes. It was awful! The worst thing in this thing is that you need to buy another battery for your ev3 and you can't use your nxt 2.0 battery! My ev3 was a gift and I am was very angry because of this.

  This product saves you so much money because you can just recharge it over and over again. when I use it at school it saves so many batteries. The robot i have at home I use batteries and I used a total of 3 Kirkland batteries packs. That costs a lot and is not Eco friendly. with this batteries it is Eco friendly and saves you money. PST...You have to buy the cord separate
