Circuit Blox™ - Battery Holder - E-Blox®

This little battery holder snaps securely into the Circuit Blox builds and keeps the batteries firmly in place, so the lights and buzzers stay powered without flickering.

My kid's old set was missing this exact piece, so I grabbed a replacement and it clicks in just as snugly as the originals. The battery contacts line up perfectly, no wiggling or dead connections so far.

Snapped right into our existing building set, no wobble at all once the batteries are seated. My daughter rebuilt her light-up tower three times in one afternoon and it never lost connection.
