LEGO has - for decades - has had a standard, very basic and awesome system of delivering electricity from a ‘power brick’ that contains standard AA or 9V batteries.

It’s very cool, they’ve got little metal clips under these special conductive bricks.

If you’ve ever played with MindStorms, you’ll know how bloody cool it is.

So you don’t have to worry about ‘Lego(c)(r) Mini Batteries’ - if you’d read the article; you’d see, that brilliantly - this is actually already the way the pieces are powered!

They have no batteries in them.

If you can’t see the value of working displays in especially a collector’s (adult) edition of, say, the X-Wing with that Death Star trench thing, then it’s not a product for you - but I assure you there are thousands of us who will happily say ‘shut up and take my money’ for such a thing.
