Battery Box check
The Battery Box is the heart of every LEGO® Power Functions setup.
- Make sure that you’re using six new, non-rechargeable alkaline batteries of the same brand and put them in the right way. You’ll need AA or AAA batteries depending on which battery box you have. If you have a rechargeable Power Functions Battery Box, make sure it’s charged before continuing. If the red light does not come on when you plug your charger in, try another charger or get in touch with us.
- Turn on your battery box. The light should be a solid green. If no lights come on or the light flickers, get in touch with us.
